Serebryanka is a heat-resistant paint and varnish material for metal, which is in demand not only in industry, but also in households. You can purchase the material ready-made, but sometimes it has to be prepared from powder at home.
Serebryanka is a heat-resistant paint and varnish material for metal.
Brief description of the material
Silver paint for metal is necessary for painting the material with a silver tint. The substance does not contain this metal. This universal paint and varnish product is able to create a smooth surface and also protect it from the negative effects of the environment. The composition can withstand high temperatures and can also be used not only outside, but also inside. To carry out coloring, the master will need to dilute the dry powder.
Composition and overview of material characteristics
The composition of the coloring agent for metal contains aluminum in different grinds, hence the specific color for the metal composition.
Aluminum powder is often used to paint high-temperature objects. The manufacturer also adds fine aluminum to the metal paint; visual differences are almost impossible to find. In addition, such products contain varnish.
Serebryanka has a rich silver color that can improve the external characteristics of a metal product. The composition lies on the surface in a dense, even layer and thus hides all its defects. You can dilute dry paint at home. The result may be either a heat-resistant or a regular mixture. To simplify the task, you can buy ready-made material.
Why is silverfish so popular?
People have been using this paint for decades. This composition is characterized by a lot of positive characteristics, which is why it is currently in demand among consumers. In industry and the national economy, silver is popular due to its affordable cost, reliability and ease of use.
Application of silverfish
In everyday life, the powdery composition is used for decorative purposes. It is used for painting house fences and interior items. Paint is even used when finishing swimming pools.
Before diluting silverware, the master should find out where it can be used. This point directly affects the method of diluting the powdered substance.
The composition is often used to finish the following items:
- parts in production;
- radiators;
- components from tanks, boilers;
- elements of ship vessels;
- port structures;
- pipeline.
This aluminum-based coloring composition is considered the best for finishing surfaces that suffer from the negative effects of external factors. The characteristic composition of the product allows it to prevent the harmful effects of sunlight and precipitation.
Advantages and disadvantages
Advantageous characteristics of silverfish:
- Convenient to use. The applied layer of paint makes the surface smooth and neat, without streaks.
- Durable. Despite the small thickness of the paint layer, it adheres firmly to the metal and does not peel off.
- Universal in use. Often the composition is used for painting metal, but due to the presence of aluminum in it, painting wood and stone is possible.
- Environmentally safe. There are no toxic ingredients in silver powder.
- It looks aesthetically attractive.
- Durable. According to consumer reviews, after painting the surface does not require updating for 6 years. As for its use inside a building, the coating can last up to 15 years.
- Heat resistant.
The material has few negative properties.
However, it can be noted that the universal composition of the coloring substance is characterized by an explosion hazard and the inability to be applied to a surface that has been treated with an oil, alkyd composition or nitro-enamel.
Application area
The scope of application extends to the private and industrial sectors. These can be hydraulic structures, swimming pools, reservoirs and technical equipment with individual parts. Silver is relevant in shipbuilding, automotive production, and public utilities. Architects paint sculptures and monuments, artisans decorate crafts and souvenirs, and ordinary people decorate fences and heating radiators.

How to make silver coin at home
Before you think about how to dilute paint powder, you should learn about its types. Each of the groups of this substance can be used for certain types of surfaces and with a specific task. The production of paint and varnish composition at home is carried out by dilution.
Common silverfish
Aluminum powder is used to make ordinary silver paint, which can be used to coat not only metal, but also wooden and concrete areas. The composition can also include synthetic drying oil and non-thermal varnish.
Heat resistant
Serebryanka, capable of withstanding temperatures of 300 - 450 degrees above zero, is used for metal processing. It is obtained by diluting aluminum powder composition and bitumen varnish BT - 577. The proportion should be 1 to 5.
Products resistant to high temperatures are used in the following cases:
- painting of cast iron batteries;
- pipeline painting;
- construction of bridges;
- finishing of boiler parts to create a protective heat-resistant layer.
Aluminum dye classification
The question of how silver paint is prepared arises after each type has been studied. Moreover, each of them is designed for application to a specific surface, taking into account operating conditions.
Two types of metal powder are produced:
They differ from each other in the grain of aluminum powder: PAP-1 consists of large grains of metal, PAP-2 consists of small particles. The creation of powder is regulated by GOST 5631-79. The degree of grinding does not affect the quality of the coating in any way. BT-577 varnish is added to the powdered silver of the first group. The powder:varnish ratio is maintained at 1:5. Silver powder of the second group is diluted with synthetic drying oil or non-thermal varnish.
The proportionality of powder: non-thermal varnish like 1:3 or powder: synthetic drying oil like 1:4 is important.
Paint that can withstand surface overheating
Before diluting silver to paint metal, purchase a varnish based on bitumen BT-577. The proportionality of powder and varnish is maintained: 1 share of powder and 5 shares of varnish. A heat-resistant dye is produced for metal surfaces that can be heated up to 400°C.
Scope of application of heat-resistant composition:
To the question: how to dilute the first group of silver powder and whether there is an alternative to BT-577, the answer is simple - a heat-resistant varnish with similar technical characteristics is used.
The protective aluminum layer will last 3 years in an aquatic environment, and a maximum of 7 years in the open air. At the same time, the decorative properties are not lost. The deadlines are declared by the manufacturer, but in fact they are longer. Indoor decor lasts about 15 years.

The finished composition is applied to wood, concrete-cement surface, brick, and ceramic elements. Each manufacturer has its own recipe ratio of powder and varnish. On average, this is 20% - aluminum powder or zinc powder; 80% – varnish. The proportional ratio is indicated on the factory packaging. It can change if pigment is introduced into the composition of the CM.
How and how to dilute silver powder
Everyone has heard about the existence of silver-colored paint, but not everyone knows how to dilute silver paint for painting metal. If the product was purchased in powder form, then it will need to be prepared before applying to the surface. Dilute the dye with drying oil and varnish. In this process, it is very important to mix the ingredients correctly.
Rules for diluting aluminum powder with varnish
To make non-heat-resistant silver, you should buy varnish. The best option in this case would be BT - 577. The master will need to take 2 units of powder and 5 units of varnish and mix thoroughly. The prepared thick paste will need to be further diluted for ease of application. Craftsmen should give preference to turpentine or solvent as a solvent.
How to dilute silver with drying oil
In addition to varnish, the coloring composition for the metal base is diluted with drying oil.
The synthetic product can be used for dads - 1 and dads - 2. Diluted paint is not resistant to temperature changes.
Correct dilution of the material:
- The proportions for preparing pap - 2 are 1: 3 or 1: 4.
- Pap-2 is prepared with a component ratio of 2:5.
Required thickness
Depending on the painting option, the density of the silver is selected.
In the case of using a spray, both substances are taken in the same quantity. A thicker product is applied to the surface using rollers and brushes. In this case, the solvent used is 2 times less than the powder. To prepare a heat-resistant composition of the required density, toluene is used. If the silver is ordinary, then turpentine and white spirit are more suitable for it.
§ 7. Preparation of various putties, mastics, sealants
Portland cement, tripoli, chalk, ash, slag limestone and dolomite flour, sifted on a sieve, with a moisture content not exceeding 4% (by weight) are used as fillers. To improve the quality of putties, it is advisable to add from 10 to 15% asbestos of the 6th or 7th grade. Solvents include kerosene, naphtha, gasoline, varnish kerosene, benzene and solvent naphtha.
Bituminous putties are prepared as follows. Bitumen (or coal tar pitch) is loaded into a boiler or tank with a tightly closed lid and heated. As soon as it begins to foam, remove all floating particles from its surface. Heat the bitumen until foaming stops. Then the fire is extinguished, the molten bitumen is cooled to a temperature of 70-80 ° C and only after that kerosene, naphtha or gasoline is introduced into it in large portions with thorough mixing (in coal tar pitch - anthracene oil, benzene or solvent naphtha). Everything is thoroughly mixed until a homogeneous liquid mass or solution is obtained, which is poured into a hermetically sealed container and subsequently used as a cold binder. Shelf life: 2-3 months. With longer storage, it delaminates. To prepare the putty, add filler to the resulting solution and mix everything until a homogeneous crumbly mass is obtained.
Paint application technology
For high-quality painting of metal, a brush, spray gun, or roller can be used. In addition, special attention should be paid to surface preparation. For this purpose, the following actions are performed:
- clean the surface with a brush;
- sweep away garbage;
- eliminate rust using special means.
Application technique
Metal finishing with silver should be carried out according to the following principle:
- Preparing the metal surface, degreasing it with a solvent.
- Waiting for the solvent to dry. After this, you can start mixing the paint.
- Applying a layer of primer to previously prepared material.
- Painting the surface after the primer has completely dried.
If it is necessary to create reliable protection of the coating from the negative influence of chemical and physical factors, the paint is applied in three layers. Applying each new layer can begin after the previous one has dried.
Features of silver coating
Surface painting is carried out only on a clean surface, with a substance with a good shelf life. At the same time, the master should remember that applying this paint and varnish material is not possible on any surface. For example, silver is not used over nitro enamel, oil paint, or nbh enamel.
A little silver paint is needed for the primed coating. Another important rule in painting metal is the speed of work, that is, you need to paint the surface with this composition as quickly as possible.
How to wash off paint
During operation, paint may get on interior items. To prevent such a nuisance from happening, it is recommended to cover furniture, windows and doors with film. If the paint and varnish composition gets on the floor, it can be removed using proven methods.
Traditional methods of removing paint
If you need to eliminate silverfish from the surface, you can use sunflower oil, which is available in every home. To do this, apply a small amount of fat to the stain, wait a few minutes and wash it off. The second no less effective method of getting rid of silver is considered to be a liquid for eliminating varnish without acetone in the base. This substance eliminates the problem well if the stains are fresh.
The process of breeding on drying oil
Serebryanka has a number of undeniable advantages:
However, despite the impressive list of advantages, this paint has a number of disadvantages:
The process of diluting silver with drying oil is divided into three stages:
1. Preparation. Before proceeding with the procedure, you need to prepare the necessary tools and devices. For these purposes you will need rubber gloves, an unnecessary jar and a brush. In addition, you need to prepare drying oil, which you will directly use to dilute the silverfish in the required proportion. Drying oil must withstand temperatures up to 350 degrees.
Note! It is also important to protect the skin from contact with the mixture; if contact occurs, the skin must be washed well with soap and warm water and wiped dry.
2. Making the mixture. When mixing the ingredients, the paint should not be thick enough. If the density is higher than normal, white spirit or another solvent should be used.
Note! The solvent is added to the composition in a ratio of 1 to 5. Only in this case the paint will not be very thick, and at the same time it will not spread over the surface.
Proportions
How to properly dilute silver linseed oil? In order for the composition to be stable and lay evenly on the surface, certain proportions must be observed. As mentioned earlier, the dilution ratio depends on the type of silverfish:
The mixture is mixed well and a solvent is added at the end of the procedure.
Breeding Features
In addition to the listed nuances of diluting silver linseed oil, there are some features of this procedure:
The process of diluting silver powder with drying oil is not particularly complicated. The main thing in this procedure is strict adherence to proportions and sequence of actions. Otherwise, the paint will lose its properties, will apply unevenly and will last much less.
It is also important in the process to ensure protection from contact of the composition with the skin and mucous membranes. For these purposes, gloves and goggles are used. It is better to carry out work in the fresh air, which will protect you from inhaling harmful vapors of drying oil and solvent.

Where is liquid silver used?
Silver powder is a fairly popular material and is widely used both in everyday life and at industrial facilities. Silver paint is used for painting:
- bridges;
- parts of production workshops;
- radiator systems and central heating batteries;
- parts of ships, floating stations and docks, port and underwater structures;
- various pipes and metal elements;
- parts of systems that need to be protected from overheating;
- sculptures, monuments, grave fences, souvenirs and other items.
Flaws
Before diluting “silver” (powder) for painting metal and other surfaces, let’s talk not only about the advantages, but also about the disadvantages of this material. There are few of them:
- Dry powder is quite explosive, so you should store it away from fire in a tightly sealed container. You should also keep silver powder away from children.
- Silver paint cannot be applied to surfaces previously painted with oil, NBC or alkyd paints, as well as nitro enamel. When applying silver to such surfaces, bubbles may appear. The paint does not adhere well or comes off completely.
- Contrary to advertising, acrylic “silver” not only does not have all the wonderful properties of conventional paint, but also shows traces of rust already at the time of painting.
- A solution of silver aluminum powder cannot be used to paint galvanized parts. The contact of these two compounds quickly destroys the zinc coating. If the need to paint galvanized steel is too great, cover it with a couple of layers of a special primer.
Advantages
The widespread use of this paint and varnish product is due to its positive properties.
Here are just some of the advantages of this paint:
- it covers surfaces like a second skin, lies evenly and in a fairly thin layer;
- “Silver” can be used to cover almost all types of surfaces: wood, metal, ceramics, concrete, plastic and others;
- the coating is absolutely not subject to rust, does not flake off or peel, adhering tightly to the surface;
- can be resistant to high temperatures;
- itself is non-toxic and dries very quickly;
- Compared to other coloring materials, silver has a long service life: 3 years under water, 6–7 years outdoors, more than 10 years indoors;
- materials painted silver look quite original and attract attention.
