Designation of primers by type of film-forming substance

Table A.1

Oily soils

What is an oil primer? This is an alkyd mixture based on synthetic oil resins; it also contains grated paint and drying oil, thanks to these components you can choose the color of the primer. If the composition is supplied in the form of a spray or aerosol, the can must contain a solvent. And if the solution is in a metal can, then the composition will not contain solvents; it must be applied either with a roller or a brush.

To protect yourself from purchasing counterfeit, low-quality goods, you must purchase a solution that has a quality certificate. Such a mixture will have the best characteristics; an oil primer certificate is a document confirming that the product complies with GOST and the requirements of other regulatory documents.

Purpose

To ensure that the finishing material adheres firmly to the walls and ceiling, when performing interior repair work, the base must be covered with a primer mixture before painting or wallpapering. Thanks to priming, the finish will be durable, will not crack or fall off, and the wallpaper will not peel off or peel off.

The high technical characteristics of the primer allow it to significantly increase the adhesion rate of plaster, putty and finishing materials, so the walls and ceiling will remain attractive for a long time, remaining the same as they were immediately after the repair. There are many primer compositions on the market and in stores, and it is very easy for the average person to get confused, because it may not be clear which type is best to choose.

Purpose of wood processing

A primer for wood is an acrylic, alkyd, mineral and oil-based liquid containing resins, plasticizers, glue, antiseptics, pigments and other components that prepare the surface for further painting or varnishing. The choice of composition depends on the type of wood and the expected conditions of its use, and the type of subsequent staining.

When processing lumber, the primer performs a number of tasks:

• disinfects, destroying mold spores, putrefactive bacteria, parasite larvae;
• impregnates the top layer of the material, binds the fibers, fills the pores, smoothes the pile and creates a protective waterproof film that prevents erosive processes, swelling and destruction;
• Depending on the purpose, it evens out the color, emphasizes the natural wood grain, and hides stains;
• improves adhesive properties, helping to ensure optimal adhesion of surfaces;
• saves the consumption of varnishes and paints.

Primer compositions differ in the depth of penetration, the time required for complete drying, and the degree of protection created. Depending on the characteristics, some products are suitable only for interior work, others are also used for finishing wooden parts, walls of rooms and buildings outside.

Main advantages

The excellent characteristics of the oil primer give it the following advantages:

• serves as a reliable protection for the base, which is subsequently painted with any oil paint;
• products or structures made of wood acquire a high level of resistance to moisture;
• is a natural antiseptic for surfaces;
• Since the mixture can be tinted, it is very easy to decorate the primed base. In addition, the shade and texture of the primer will not be visible through the paint layer.

Types of oil-based primers

There are 2 types of acrylic and oil primers sold in stores:

• universal primers have the best technical characteristics, thanks to which these mixtures can be used for treating concrete and brick bases, but they cannot be used for priming any metals and wood. Universal primers are great for protecting walls and ceilings before wallpapering or painting;
• Primer-paints are used to coat wood and metals. In addition to effectively protecting the surface and enhancing adhesion, these oil-based primers also have antifungal properties. Usually available in white, so the primed surface looks like it has been painted.

Priming rules

The primer must match the composition of the paint that will be applied over the primer. The store purchases a suitable type of primer, as well as the following tools:

• a cuvette container with a ribbed area for spinning. This container will be used to pour the primer mixture;
• brush and roller for surface treatment;
• If you don’t have a stepladder, you need to buy a telescopic handle.

Before you start priming walls, ceilings, or any other structures and products, you need to remove dirt, dust, remnants of old finishing materials, greasy stains, and other contaminants from them. If metal is to be primed, it must be cleaned of rust.

The finished primer is poured into a ditch, a roller or brush is lowered into the mixture, passed over the ribbed surface several times to remove excess composition, after which the mixture is applied to the surface. It is advisable to apply two coats of primer, but make sure that the first coat of primer is completely dry before applying the second coat. Drying time depends on the temperature and humidity in the room. Even a beginner can handle priming; there is nothing difficult about it.

Main characteristics

Below are the technical characteristics of the oil primer.

Typically, these types of primers have a matte color, due to which they are considered universal because they can be tinted. Typically, an oil-based primer has a consumption of 50 to 100 grams per square meter, this parameter depends on what surface the mixture is applied to and what absorbent properties the base has.

The thickness of one layer of oil primer is less than 1 millimeter. Under normal conditions of use, the primer coat is completely dry in approximately 24 hours. After this time, you can begin applying the next layer. Before applying a layer of oil primer, the manufacturer recommends stirring the mixture thoroughly.

Application

At the first stage, we prepare the surface for applying the PRIMER - it must be clean and dry (the maximum permissible level of wood moisture is 12%). The varnish or paint coating must be removed using a solvent or by grinding (final abrasive with a grain size of 120-150). After sanding, carefully remove any resulting wood dust.

Öl-Grundierung wood primer for interior use must be mixed well before use and not diluted. Apply thinly with a spatula and distribute evenly. The amount of material applied is about 15 g/m2, depending on the type of wood, application method and other factors.

Within 30 minutes, smooth the surface treated with a spatula to remove streaks using a grinding machine with a white pad.

In floors with chamfers, level the primer with a brush in the longitudinal direction or use a machine with brushes in such a way as to remove excess primer from the chamfers. Or apply with a roller with the minimum possible flow rate without pressure to prevent the material from flowing into the chamfers. Then remove excess primer with a white pad or rag. Rub the primer into the chamfers with a rag.

To achieve uniformity and color saturation of the painted surface of combined floors, we recommend that before applying the primer, moisten the painted surface with water to raise the pile. In this case, the color intensity will increase.

A comprehensive system for protecting wooden flooring and furniture surfaces subject to particularly high loads consists of:

• applying Öl-Grundirung (1st layer);
• topcoat – as a topcoat you can choose either Premium Hartwachsöl. hard wax oil or Ecoline MultiTop varnish.

Drying and curing

Drying time for each layer is 8-10 hours (depending on temperature and air humidity). After drying, treat the surface with a polishing machine with a white pad.

GOST R 51693-2000 Anti-corrosion primers. General technical conditions

Professional experts advise that you must prime the surface of walls and ceilings before painting or wallpapering them. People who are far from the sphere of repair and finishing work may think that priming is not such an important procedure. However, experienced finishers say that priming the surface is a very important step during repairs; this procedure cannot be neglected. There are several types of primer compositions, one of the widely used ones is oil primer. The main properties, purpose and types of this soil will be discussed in this article.
