Paint primer enamel for rust 3 in 1 consumption per 1 m2

One of the most common methods for repairing metal surfaces today is enamel, which is presented to customers in a wide range. As an example, consider primer-enamel XB-0278. This composition is in the form of a suspension, which contains, among the ingredients, fillers and pigments in a solution of polymerization polycondensation resin and organic solvents. During the manufacturing process, modifying substances are added to the ingredients.

As a result, manufacturers managed to obtain a mixture, using which it is possible to eliminate the need to purchase compositions that decorate the surface and transform rust. This helps save not only money, but also effort when carrying out work. In addition, there is no need to wait too long between coats.

Mode of application

Before you start using the enamel primer, it must be mixed well. The surface is freed from dirt, dust, peeling coatings, as well as rust, which has acquired a loose state. The surface must first be degreased. If the base or products were painted with oil or alkyd paints, then it is necessary to clean them to a matte state. It is unacceptable to apply when the ambient temperature has risen above +30 degrees. Wait an hour or more between coats. As for the complete drying time, this period lasts 2 hours.

Consumption rates per 1m2

All of the above characteristics have a positive effect on enamel consumption. But if painting takes place in windy or sunny weather, the amount of paint used per m2 will double. Light-colored oil paint is applied in two layers; one will not be enough, as streaks and gaps will be visible. Therefore, when choosing white, gray or yellow, enamel must be purchased with a reserve.

Before painting, prepare the surface of the walls or ceiling. First, wipe it with a damp cloth to remove dirt and accumulated dust. In order to save paint and varnish materials, level the walls with putty and treat with a primer. Thanks to the primer, adhesion (adhesion) and service life of the material are increased.

As practice shows, the rate of material consumption varies from 100 to 180 g. Also, professionals say that on average a can weighing one kilogram is enough to paint 15 m2 of prepared surface. Also, the consumption of PF 115 directly depends on the selected color pigment.

Table of approximate consumption of PF-115 enamel (depending on the selected color)

A spray gun is also suitable; thanks to the fine dispersing jet, the enamel is applied evenly. Brushes absorb a lot of paint, which increases the consumption of material several times.

When calculating enamel consumption rates, add to the total amount the percentage of loss due to the location of the surface. If the floor is painted, the paint will not flow or drip, but for the walls and ceiling you will have to purchase extra material (approximately + 7%).

Do not forget that when painting a wooden surface, the paint will have to be applied in several layers, since wood, due to its uneven structure, absorbs a large amount of material. Consequently, paint consumption will increase. When covering metal surfaces, it is necessary to treat them from rust and contamination, and only then paint them with the desired shade. In some cases, one layer is enough. Plastic is less whimsical.

If you bought more paint than you needed, you can return it to the store within two weeks. To do this, the cans must be unopened; take the receipt for the goods and your passport with you.

Consumption per 1 m2

Calculation of paint consumption on the surface must be done before purchasing to save time and money. Standard values ​​are indicated by the manufacturer. Instructions are located on the packaging.

The economy of the composition largely depends on the correct preparation of the base. The opened enamel must be thoroughly mixed and diluted with special solvents or xylene, after which the surface can be prepared for application. To do this, you need to remove dirt and rust from the base, after which you need to thoroughly degrease it. If there is a layer of previous enamel, such as oil or alkyd paint, it should be cleaned. It is prohibited to apply primer-enamel over a nitro-containing coating.

It is recommended to apply enamel primer in 2 layers, taking a break of about an hour. When the composition is applied and dried, it can be coated with any paint and varnish material.

If you follow the application technology, the consumption of the composition will be about 80-100 milliliters per 1 m2. The number of layers depends on the needs and desires of the consumer and can range from 1 to 4.

How to dilute

First of all, you should carefully read the instructions on the packaging; as a rule, it contains a list of compatible solvents. In general, 3 in 1 enamel primer for rust and other alkyd-based paintwork materials are diluted with solvent, white spirit or xylene. The solvent content should not exceed 10% by volume.

If an acrylate dispersion is used as a base (for example, “Chief Technologist”), clean cold water should be used as a solvent.

The best paints for rust 3 in 1

The presence of the “3 in 1” prefix indicates that the product works in several directions - primes, transforms rust and decorates. Products of this type are resistant to any impact. After analyzing reviews from consumers and experts, two nominees with the best recommendations were selected from among a variety of products.

Novbytkhim primer-enamel

Novbytkhim primer-enamel paint is intended for painting any type of surface. It is applicable both on new and already partially or completely corroded products. The composition of the product consists of resins of synthetic origin, additives, solvents (organics) and anti-corrosion components. The product combines the qualities of an anti-corrosion primer, a rust converter and a finishing enamel. Its consumption is quite small - up to 120 ml per m² when applied in a single layer.

Work can begin at an air temperature of -10°C. The coating is pre-cleaned from existing detachments. If it was painted with oil or alkyd compounds, then cleaning to a matte state is necessary. A brush and roller are suitable for applying the composition. The paint also adheres well when applied by air. For best results, apply 2 layers. Intermediate drying should last at least 60 minutes. It only takes 2 hours to dry completely.

Advantages

• Quick drying;
• Resistance to different types of exposure and temperature changes;
• High adhesion rates;
• Excellent decorative properties;
• Good hiding power.

Flaws

Not suitable for heated surfaces due to odor.

Metallista

The paint in question for rusty metal from a myrrh brand called Tikkurila provides a “3 in 1” effect. Thanks to the wax included in it, it creates increased protection of the metal from the negative effects of moisture, giving it excellent water-repellent properties. Structures coated with the composition will last at least a decade without updating. Metallista is immune to the effects of fats, lubricants, technical alcohols and turpentine, so its scope of application is unusually wide.

The manufacturer offers several basic shades for tinting, but in total they can be created up to 32 thousand. The hardened layer can easily withstand heating up to 80°C while maintaining the original color. It takes up to 2 hours for the applied composition to dry before it sticks. Before using Metallista, you need to add solvent. It fits well on uncleaned surfaces without first applying primer.

Advantages

• Creation of an insoluble base;
• Delay in corrosion formation;
• Eliminates the need for preliminary preparation of the base;
• Double chemical formula;
• Ease of use with any tool.

Flaws

• Sales in small volumes;
• The need for tinting;
• Not a very large number of ready-made colors (four).

Enamel is sold in small containers – from 400 ml to 2.5 liters.

Properties and application of primer enamel

Novbytkhim primer enamel has a very wide range of applications. It can be used for protective and decorative finishing of glossy, matte and rusty metal surfaces. Primer enamel 3 in 1 for hammerite rust?

The composition is in demand in everyday life for painting various fences, garages, gates, doors, safes, window grilles, furniture, etc. In addition, it is used to treat bridges, power lines, and agricultural machinery.

Primer enamel is used for painting products that are difficult to clean from rust for some reason: due to large dimensions, complex profile, lack of conditions.

The composition is suitable for treating rusty internal surfaces of cars: underbody, wings, etc. After drying, the enamel forms a coating that is resistant to salt water, mineral oils, as well as sudden temperature changes (withstands operation in the range from –45°C to + 60°C).

Paint for metal and rust is a universal 3-in-1 product; it combines the properties of an anti-corrosion primer, a rust converter and decorative enamel. Another advantage is the fact that the composition is diluted with water, does not have an unpleasant odor and does not emit harmful volatile substances.

The manufacturer does not recommend using enamel primer for finishing heated surfaces that are planned to be used indoors.

Surface preparation

Remove the flaking coating from previously painted surfaces with a scraper, and then clean them with a steel brush. Contaminated items are washed with a solution of washing powder, rinsed and dried.

Oil and grease stains are removed with a rag soaked in white spirit.

It is also recommended to do a test application of enamel primer on previously painted surfaces. In case of swelling or peeling of the old coating, it is removed with a special remover.

On unpainted products made of steel and ferrous metals, 3 in 1 paint from Novbytkhim is applied without prior priming. You just need to make sure that the surface is free of dirt.

When working with galvanized metal or aluminum, glossy surfaces are sanded to a matte texture, and dust from grinding is removed. The product is then washed with water and dried. Before painting, apply one coat of Hammerite Special Metals Primer or similar products from other manufacturers, for example: Grit Metal or Rostex Super (Tikkurila).

Rusty metal surfaces are cleaned of loose and loose fragments using a metal brush or sandpaper to a solid base. The surface is washed with water and dried. Preliminary priming is not required in this case.

Technology

In order to paint metal outdoors and still obtain a reliable and durable protective coating, you must adhere to certain rules. This may seem unnecessary, but there are clear standards for painting metal surfaces, prescribed in Construction Regulations. To begin with, even before choosing materials, you should inspect the surface and assess its condition.

Determining the quality of the metal

At this stage, you should evaluate the surface, but also understand what kind of metal will be painted. Ferrous and non-ferrous metals are used in everyday life, and ferrous processed metal, for example, galvanized, should be highlighted in a separate line. For each of the 3 types, professionals recommend their own paintwork materials:

• for processing structures made of ferrous metals, including galvanized ones, in outdoor conditions, it is better to choose alkyd compounds;
• For non-ferrous metals, epoxy material is suitable, and it is better not to paint, but to colorless varnish.

If the metal has already been painted before, and the layer of old paint is firmly ingrained and there is no way to remove it, then a material is selected that does not conflict with the old coating.

Sequence of work execution

It depends on how well the surface is prepared before painting. The strength and durability of the coating depends. The specificity of painting metal, especially in outdoor conditions, is that the interaction of unprotected iron and moisture from the air should be minimized. That is, all work must be performed one by one without delay.

Step 1. Cleaning the surface. First of all, the surface to be treated is cleaned of dirt. It is necessary to sweep away all street dust to assess the condition of the metal. In places of oxidation, the iron is cleaned with a wire brush or abrasive. Using an angle grinder with a special attachment will simplify the work process. In addition to dirt and rust, the metal should be cleaned of various chemicals, that is, degreased.

Step 2: Priming. You can use special primer enamels at this stage, or you can apply the first coat of paint. The difference is that the soil will improve adhesion, reduce the consumption of the main paintwork and at the same time reliably protect the metal. You can do without special compounds, you’ll just need to apply the paint in more layers. Experts advise realistically comparing financial costs and possible risks and buying a primer. This is especially true when performing outdoor work.

Step 3. Coloring. For painting, you can choose any tool: brush, roller, spray gun - it all depends on the surface area and type of paint. The specificity of metal surfaces is that the paint is not absorbed, which means you should not apply the composition in a rich layer, because smudges will appear.

Depending on the covering ability, the compositions may have a different number of layers recommended for application. Read the instructions on the can carefully. In addition, the air temperature at which it is better to paint will also be indicated.

The nuances of coloring

In order to choose the right composition for working on metal, it is enough to clearly understand in what place and on what basis the painting will be carried out. Some simple tips from professionals:

1. Radiators and heating system pipes should be painted when they are cold, that is, before the start of the working season. In this case, the paint is selected that is heat-resistant, with a possible operating temperature of up to 150°C.
2. Surfaces of non-ferrous metals must be treated with a suitable primer before painting.
3. When working with organic solvent-based paint, personal protective equipment should be used, and the room should be well ventilated.
4. Make sure the tool is suitable for your paint. Not all metal compounds can be applied with foam rollers or natural brushes, in addition. Quick-drying compounds should not always be applied with a spray gun; the mechanism can be damaged.

The best hammer paints for rust

Hammer paints form a specific rough coating, creating the effect of being hammered. At the same time, the enamel perfectly protects against moisture and temperature changes. After assessing the technical characteristics and feedback from specialists, 2 winners were selected that met the necessary requirements.

Hammerite

...I used enamel to paint a metal door to evaluate the strength of the hammer effect. Hammerite well masks unevenness that has arisen during the use of the canvas and creates a visually impressive coating... Expert opinion

Another best anti-rust paint to protect metal during both exterior and interior work. It adheres well to substrates with signs of rust due to its high adhesion rate. The enamel creates a smooth coating with excellent water-repellent properties even on a rusty, unprepared surface and completely hardens within 2 hours after application. The product has excellent heat resistance, maintaining its integrity even when heated (up to 80°C).

Hammerite is designed to protect ferrous metals exclusively. It contains corrosion-inhibiting components - alkyd varnish, sunlight-resistant pigments and functional additives. It is allowed to start painting when the air is heated to 5°C with a roller, brush or spray, which allows you to choose the most convenient tool in each specific case. After applying the base coat, wait at least 5 hours. The manufacturer offers 11 shades.

Advantages

• Resistance to aggressive factors;
• Ease of application to corrosion areas;
• Does not require preparatory work;
• Suitable for outdoor and indoor work;
• Lead free.

Flaws

• Not low cost;
• Hammerite solvent is required for dilution.

Zip Guard

This is a urethane rustproof paint designed for metal surfaces, but it is also suitable for concrete and wood. Enamel can be used directly in areas with signs of corrosion. In this case, it is not necessary to carry out any actions to clean the affected areas, except in cases where there is swelling of the old coating - they must be removed.

In the production of Zip Guard, the Ziprust technology is used, which allows you to apply a layer without the prior use of primers. Enamel can be used for interior and exterior work. It is a one-component composition and creates a corrosion-resistant coating due to the combination of the properties of the soil, anti-corrosion components and the finishing composition.

Advantages

• Protection of all types of surfaces, not just metal;
• There is no need for surface preparation;
• Suitability for external and internal work;
• Creation of a durable coating with anti-corrosion properties.

Flaws

• Glossy surfaces must be sanded before painting;
• It takes a long time to dry.

Where should a modifier primer not be used?

Scale is resistant to phosphoric acid, so applying a primer containing a rust converter to such surfaces is not recommended. If black rust has formed on the surface, this indicates that the alloy contains magnetite, which is also resistant to modifiers.

You cannot use compositions with rust modifiers on surfaces where oxidation has occurred partially and most of it is metal without corrosion. Uncleaned paint, like scale, will also not interact with the converter, and the primer will not be able to penetrate through it. If during operation the metal structure was exposed to sulfur, hydrogen sulfide or ammonia compounds, then the use of a primer based on orthophosphoric acid is also inappropriate.

Composition and technical characteristics

Hammer or other primer has a good effect when used on a metal surface. All properties are available thanks to the composition of this substance, which includes the following components:

• First of all, this substance contains alkyd varnish, which promotes adhesion to the surface;
• there are various functional additives to reduce the impact of sand on the structure;
• in addition, the components of this solution contain special enzymes, as well as organic and inorganic fillers;
• among other things, the structure of this coating contains organic fillers and auxiliary pigments.

As a rule, the main purpose of pigments is to give the composition a certain shade. Often, this type of ground-effect enamel is black in color, which is why its use is widespread in practice. Depending on the aerosol filling and production technology, such a dye has a specific purpose. Most often it is anti-corrosion protection of a metal surface.

Consumption per 1m2

Before considering how long this composition option takes to dry, it is necessary to clarify the consumption of this enamel per 1 m2. In this case, the following indicators are established:

1. as a rule, with correct and rational application, a layer of 0.1 millimeters is formed;
2. if we talk about a single-layer coating, then per square meter it takes from 130 to 140 grams of composition;
3. provided that the application technology is not followed, and in addition a brush or roller is used, then the consumption may increase to 200 grams.

It should be understood that all these values ​​are prescribed by the paint manufacturer and are not always preserved in practice. In this case, the composition consumption during normal use can vary from 130 to 250 grams.

Tool selection

Anti-rust paint can be applied in several ways: roller, brush, spray. Before using the composition, you need to cover the skin of your hands with rubber gloves. For processing, it is recommended to use thick and wide brushes made from natural fibers.

If the treatment is carried out by spray, then for these purposes it is worth using a paint sprayer that is made of metal and does not contain plastic parts.

The enamel is applied in several layers; thirty minutes is enough for the composition to dry.

Advantages and disadvantages

This type of paint coating has a number of positive and negative qualities. Let's take a closer look at the main advantages of the coating:

1. this composition dries quickly enough;
2. the necessary protective property for the surface is present;
3. minor existing corrosion is eliminated;
4. relatively low cost;
5. there is no need to buy different materials for work;
6. can be used for any purpose.

Despite a number of advantages, there are also some disadvantages. Small temperature range for operation. At high humidity, the composition hardens slowly. If used as a full coating, polishing is required.

Advantages and disadvantages

Let's take a closer look at the advantages and disadvantages of the material that are typical for all manufacturers.

The undeniable advantages of primer-enamel over classical protective coatings (meaning primer GF-021 and enamel PF-115) include the following points:

1. Surface preparation is greatly simplified when using an anti-corrosion compound. Its application does not require thorough cleaning of rust-affected areas and additional surface treatment with a special modifier, followed by its neutralization with a soda solution. Primer enamel can be applied even to residual rust; it is enough to remove the peeling coating and loose corrosion formations from the surface being treated.
2. The decorative and protective properties of the material are noticeably higher than those of alkyd coatings. Alkyd-urethane varnish, acting as a binding element, has greater hardness, wear resistance and is less susceptible to moisture and aggressive environments than alkyd varnish used in primers such as GF-021 and enamel PF-115.

To ensure reliable anti-corrosion protection for 5 years, it is necessary to apply one layer of GF type primer and two layers of PF-115 enamel, while enamel primer is sufficient to apply in two layers. When applying three layers, the service life of the decorative protective coating increases to 7 years.

1. The use of the material can significantly reduce the time required for painting work. It should be recalled here that the GF-021 primer dries within 12 hours, and one layer of PF-15 enamel completely polymerizes in 24 hours. Thus, to obtain a protective coating it will take: 12+24+24=60 hours.

One layer of the composition at an ambient temperature of 20C does not exceed 6 hours, which allows you to completely complete painting work in 12 hours.

1. All components of the protective coating (rust modifier, primer and enamel) are in one can, which greatly simplifies their application and reduces the number of tools required.

The main, and perhaps the only, disadvantage of primer-enamel is their high cost, however, upon closer examination, this disadvantage also turns out to be quite dubious. The fact is that the estimate for painting work takes into account not only the price of the material. It also takes into account the cost of preparatory work and application of each individual layer.

When using this composition, the preparatory work is significantly simplified, and the protective and decorative coating itself is applied not in three, but in two layers, so the total cost of the work differs slightly.

Differences in paint materials

Having examined all the compositions, we can conclude that enamels have pigmented components as their base, while paint has binding elements. Enamels contain only organic solvents. There are differences in physical and chemical characteristics. Also, enamel differs from paint in that enamel is harder and more elastic. But the coating is much thinner. But they have much less impact from temperature changes. Therefore, enamel is used for domestic purposes. It also has many shades and a huge selection of colors. Decoration is much more varied and interesting. Return to list

3 in 1 rust primer – what is it?

Three-in-one primer enamel is a coating for metal that combines decorative and protective functions. Consists of rust-neutralizing anti-corrosion additives, primer coating and coloring enamel.

Three-in-one primer enamel is a coating for metal that combines decorative and protective functions.

If all stages of application are followed, the service life of painted products located in the building is more than 10 years.

Purpose

As already noted, 3 in 1 primer-enamel is designed to prevent the appearance of rust on metal surfaces and protect metal structures from premature corrosion destruction. The components included in the mixture ensure the strength and elasticity of the protective and decorative coating, wear resistance and a long period of operation.

Due to their ease of application and high performance properties, primer enamels are widely used in industrial and civil construction, mechanical engineering and the housing and communal services sector. The attractive appearance of the coating allows the compositions to be used not only for protective purposes: enamel is often used for painting children's and sports grounds, metal garages, hangars, water and gas communications. The compounds are also actively used in auto repair shops.

Application

Before applying primer-enamel, the surface to be treated must be prepared: clean it of the flaking previous coating, remove large and loose pockets of rust. After this, the product should be re-cleaned from dust and dirt and, if necessary, degreased with white spirit. All this will ensure the best primer-enamel adhesion, make work easier and provide a high-quality finish coating.

Before direct use, the composition must be thoroughly mixed. Depending on the complexity and size of the surface being treated, enamel can be applied using a brush, roller or spray. Small parts can be processed by dipping.

Before covering the entire structure, it is advisable to try painting a small area to evaluate the correct color selection and the quality of the finishing layer.

The average material consumption per m2 is 80-120 ml for one layer. The number of layers applied depends on the degree of protection and the desired effect and ranges from 1 to 4. Each manufacturer indicates on the packaging recommendations for primer consumption and application method to the product.

The drying time of the primer-enamel is short: to the “touch-to-touch” stage – about 30 minutes, and the time for complete drying – about 4 hours. In order for the product to be resistant to salt, water and oil, it must be kept for several days (up to 7 days) before use.

In the open air, the process of drying the primer-enamel and removing the specific odor occurs faster than indoors. Therefore, manufacturers recommend painting the base outdoors or in a ventilated area.

For a review of primer-enamel for rust from Dali, see the following video.

Famous manufacturers

Below is a list of the most popular primer enamels and their brief description.

"Chief Technologist"

Protective primer-enamel “Chief Technologist” is produced by the Novbytkhim production association based on acrylate dispersion. The composition is intended for applying a decorative and protective coating on matte, glossy and galvanized surfaces, as well as on surfaces covered with a layer of residual rust whose thickness does not exceed 100 microns.

The coating is applied in two layers and retains its performance properties in the temperature range from -45 to +600C. Water is used as a solvent. At a temperature of 200C and a relative humidity of 50%, the single-layer coating dries completely within 2 hours. With a decrease in temperature and an increase in humidity, complete polymerization of the composition can last 3-4 hours. For a two-layer coating of 1 m2 you will need from 100 to 150 g. The average cost of a can with a capacity of 0.8 kg ranges from 175 to 190 rubles.

Oleg, Saratov

In the spring I noticed that the bottom of my metal garage was very rusty. In order to prevent its further destruction, the chief technologist decided to use primer-enamel. I removed the existing rust as much as possible and painted it in two layers with an ordinary brush. It's already been in its third year and it hasn't rusted. I really liked the fact that the treatment did not require any special financial expenses; I think I will paint the entire garage in the summer.

Andrey, Novosibirsk

At our dacha, the fence posts are made of metal pipes, which have become heavily rusted over the course of 5 years of service. It’s not that they fell into disrepair, but something urgently needed to be addressed. From a friend I learned about the existence of anti-corrosion paints that do not require thorough cleaning of the surface before application. My wife and I organized a cleanup: we removed the peeling good old “PF-115” and loose rust, after which we applied two layers of “Chief Technologist” primer-enamel. After two years, no traces of rust were found.

"DALI"

Primer-enamel for rust “DALI” 3 in 1 is produced by LLC NPP “Rogneda” based on a modified alkyd resin. The coating can be glossy or with a “hammer” effect. You can apply the enamel in any convenient way. Consumption for a single-layer coating will be from 70 to 100 g/m2. The composition does not lose its properties when frozen and can be stored at temperatures from -40 to +400C.

When painting, it is allowed to dilute “DALI” with solvent or xylene by no more than 10%. The composition is available in original packaging with a capacity of 0.75; 2 and 10 l. The average cost of a 0.75 liter can can be from 350 to 400 rubles.

Dmitry, Moscow region.

DALI primer enamel was used to protect the metal base of the steps from rust. I bought hammer effect paint in a bronze shade. I processed the channel with coarse sandpaper and left it at that. The enamel applies perfectly, dries quickly, and the appearance is simply wonderful. There has been no need to touch up anything for two years now. I think I made the right choice.

Alexey, Minsk

We recently installed forged fence inserts. Even at the installation stage, when the elements were stored in the shed, it became clear that rust would ruin them very quickly, so we decided to paint them with black DALI hammer-effect primer enamel. The rods were new, so I didn’t have to clean anything, I just wiped them with white spirit and that’s it. Painting was not difficult at all, and the result was simply amazing! Let's see how long the coating will last.

"Prestige"

Primer-enamel for rust 3 in 1 “Prestige”, produced by the holding company of the same name, contains alkyd varnish, drier, anti-corrosion pigments, fillers, solvent and functional additives. After drying, a durable wear-resistant coating is formed, resistant to mechanical stress, ultraviolet radiation and aggressive environments. Enamel consumption for a single-layer coating can range from 125 to 180 g/1m2.

Solvent, white spirit or petroleum xylene can be used as a solvent. Drying time for one layer at 200C and relative humidity 60-65% is no more than 6 hours Standard packaging with a capacity of 1.9 kg, the average price of a can is 375 rubles.

Alexander, Kharkov

The year before last we made vine stands from old water pipes. During this time they had become quite rusty. I learned from a good friend that the problem can be solved using primer-enamel for rust, and you don’t have to spend a lot of time and effort preparing the surface. At a hardware store, a consultant recommended buying 3 in 1 primer-enamel “Prestige”. Before applying, the pipes were treated with coarse sandpaper and wiped with a rag soaked in white spirit. I painted the structure in two layers. Over the past year I have not noticed any signs of rust.

The paint was used in a warehouse to protect metal rafters from corrosion. The channels were new, so no special preparatory work was carried out. Painted with ordinary brushes in two layers with an interval of 6 hours. For two years now there is not even a hint of rust. According to the manufacturer, there should be no problems for another three years.

"Lakra"

Lakra enamel is produced by a well-known manufacturer of paints and varnishes. The composition based on alkyd varnish optimally combines a rust converter, primer and decorative enamel. "Lakra" can be used for both external and internal processing of metal, wood and concrete surfaces.

Before application, the primer-enamel should be thoroughly mixed and brought to the desired consistency using solvent or white spirit. It will take 10 hours to dry completely at 200C. You can begin applying the next layer after 2 – 3 hours. Depending on the application method, consumption can range from 80 to 120 g/m2. A Lakra jar with a capacity of 0.8 kg can cost from 275 to 300 rubles.

Recently beautiful wrought iron bars were installed on the first floor windows. In order to reliably protect them from rust, the craftsmen advised using Lakra enamel primer. The rods were degreased with solvent, after which two layers of enamel were applied. Over the three years of service, we have not noticed any peeling of paint or rust, we are very pleased with the result.

I think it’s no secret that in greenhouses and greenhouses, high humidity leads to intense corrosion of metal frame elements. The Lakra rust composition helped me solve this problem. The most problematic areas were cleaned of loose rust, after which the entire frame was degreased with white spirit. The coating was applied in two layers with an ordinary paint brush. In a year and a half, no rust appeared.

"ProfiLux"

The use of ProfiLux rust-resistant primer allows you to provide reliable protection of metal structures, wooden elements and concrete surfaces from mechanical influences, and the harmful effects of moisture and aggressive environments. The alkyd base ensures high strength and wear resistance of the coating, and special additives prevent the appearance of rust.

To dilute the paint to a working consistency, you can use solvent, white spirit or xylene. For intermediate drying, 2 hours are enough before applying the next layer, and complete polymerization of the primer-enamel occurs in 24 hours. Material consumption for a single-layer coating does not exceed 100 g/m2. The cost of a kilogram package is about 250 rubles.

"Olecolor"

The product is used to protect metal structures, pipelines, power line supports, etc. from corrosion. Alkyd varnish, which is a binding component, provides high strength of the coating, as well as resistance to aggressive chemical compounds and atmospheric influences.

The coating is applied in two layers with an interval of 24 hours. Complete polymerization of the composition occurs within 3–4 days. Depending on the application method and the condition of the surface being treated, applying one layer may require from 80 to 150 g/m2. Xylene, solvent or white spirit can be used as solvents. The average price of a jar with a capacity of 0.9 kg can range from 320 to 350 rubles.

I used Olecolor rust enamel primer to paint a metal garage. During the work, I strictly followed the manufacturer’s instructions: I removed the peeling old paint, rust cakes and wiped the surface with a rag soaked in a solvent. I painted it with a regular roller in two layers. I must say that I am completely satisfied with the result from both a practical and aesthetic point of view.

Valery, Kyiv region.

The gas pipe located outside the house was constantly rusting. Not that it was very intensive, but every spring it had to be cleaned and repainted. A neighbor recommended painting it with an anti-corrosion compound. I bought a can of Olecolor and got to work. Since the pipe was in satisfactory condition, surface preparation did not take much time. I painted it with two layers and now, for the second year, no rust has appeared.

Specifications

There is an opinion that you can prepare an enamel primer yourself by mixing the primer with the paint you like. However, the result will probably be disastrous, because mechanical mixing will only worsen the properties of both the primer and the enamel. It's all about a special production technology for producing primer-enamel, thanks to which the primer layer will adhere to the surface of the product, and the finishing varnish layer will remain on the surface. For this purpose, various additives and additives are introduced into the composition.

The manufacturing technology of multifunctional primers gives them excellent qualities.

• Temperature resistance. It is recommended to apply primer-enamel at a temperature of 20°C - then the drying temperature and material properties declared by the manufacturer will be achieved. But if necessary, you can use it even at sub-zero temperatures. And the applied and dried primer-enamel retains all its properties at temperatures from -45°C to +100°C.
• Density and elasticity of the finished coating. If applied correctly, cracks will not appear for several years.

• Low material consumption. Compared to classic paints and varnishes, the consumption of primer-enamel will be approximately 30% less, even if the coating is applied in several layers.
• Weather resistance. Products coated with primer-enamel are resistant to sun, moisture, salt and oil, which makes this material ideal for refreshing outdoor interiors.

A variation of traditional primer enamel is hammer paint. Metal powder is additionally introduced into its composition, and the treated surface looks like it was processed by a forge - hence the name of the paint. It can be unmistakably identified by its textured “shagreen” surface and metallic sheen. It is also applied to rust, combining the functions of primer and enamel.

Due to metallic additives, this paint is more difficult to apply by spraying; a brush or roller is required when working with it. Also, on vertical surfaces, metal particles may move downward, which will deteriorate the original appearance of the product. But when applied using hammer enamel technology, it looks very impressive on interior items.
