Painting imitation timber: both inside and outside the house

Imitation timber is a lining-type finishing material that creates the illusion that the house is built of wood. Sometimes painting an imitation of a bar is a forced step. What products can be used for this?

When to paint imitation logs?

There are several reasons to paint imitation logs:

  • wood is easy to burn and some coatings increase fire resistance;
  • the material is susceptible to decay, and the finish will extend the life of the wood panels;
  • paints and varnishes protect against moisture, make wet cleaning possible;
  • painting walls allows you to update the interior design;

There are quite a few products used to paint imitation timber walls. The main thing is to choose the right product. It depends on the place where the paintwork is going to be applied - directly in the room or on the facade.

It is important to choose the right materials for several reasons:

  1. Exterior walls are subject to stronger environmental influences - ultraviolet radiation, moisture, frost, and other factors. Accordingly, the materials should have greater wear resistance.
  2. The main requirements for means for interior work are their safety and hypoallergenicity. After all, they are used even in children's rooms and bedrooms, so they must meet the hygienic requirements for such work

Some manufacturers offer already painted imitation of a bar. Choosing such a finishing material, you can save yourself the hassle.

Impregnations

Wood is a capricious material. It is susceptible to attacks by pests, microorganisms, fungi. It is also a highly flammable material.

To protect the finish from threatening factors, various protective impregnations are used:

  • antiseptics - are effective against fungi, bugs, decay;
  • flame retardants - prevent a fire or rapid spread of fire;
  • biopyrene - combined preparations that reduce the fire hazard of the material, and also protect against insects , mold, mildew.

Many of them perform not only a preventive function, but also have coloring properties. A topcoat can be used after such a product.

Attention! Often manufacturers supply to the market a finishing bar that has been treated with similar substances at the factory. This information is usually indicated on the packaging.

Wood bleaches

Often the owners of a house finished with imitation timber are faced with such a problem as surface darkening. Bleaching agents help to restore the original color of wood partially or completely. These products have a double effect - they brighten and minimize the development of fungus. Bleaching agents are based on chlorine and oxygen-containing agents.

Bleach brightens wood and destroys harmful microorganisms

Be careful when handling chlorine-based bleach , since the main active ingredient is a rather aggressive alkali.

Salt deposits remain after treatment with bleach. They must be washed off the surface of the timber. For washing wood, an aqueous solution of citric or acetic acid is used at a concentration of 4% , which neutralize the effect of salts.

If you ignore this requirement, salt deposits begin to accumulate moisture, which leads to a deterioration in the condition of the raised beam.

Another negative effect of improper bleach use is damage to cellulose and lignin. The surface of the wood looses, which leads to poor adhesion to paints and varnishes and other finishing materials.

Attention! When working with chlorine preparations, it is important to adhere to safety rules. Otherwise, chlorine vapor poisoning is likely.

Ready-made wood bleaches are on sale:

  • Neomid 500 (chlorine);
  • Senezh Effeo (based on transfer agent, without chlorine );
  • Tikkurila Homeenpoisto (active ingredient - hypochlorite ), the drug is used even for painted surfaces;
  • Sagus and others.

When working with bleaches, observe the following safety rules:

  • do not mix products, especially if they are based on different active substances;
  • in case of severe damage to the surface, higher concentrations of agents are used;
  • be sure to carefully read the instructions and strictly comply with its requirements.

Natural linseed oil

This is one of the safest coatings for human health, which has long been used for treating wooden surfaces. Among other advantages of the product are environmental friendliness, antiseptic protection. Linseed oil does not hide, but favorably emphasizes the texture of the fake timber.

But the product also has disadvantages:

  • long drying time - up to 3 days for one layer;
  • the number of layers must be not less than 5-7;
  • poor polymerization;
  • Darkening by direct sunlight.

Natural linseed oil is one of the safest coatings for imitation of a bar

Linseed oil is best suited for interior decoration on structural elements that are not subject to abrasion, such as ceilings. This type of coating is especially suitable for valuable wood species, since it preserves its properties as much as possible.

Natural drying oil

The product is a hemp or linseed oil that has undergone heat treatment with chemical additives (oil drier) that accelerate polymerization. Drying oil is devoid of some of the disadvantages of raw linseed oil. She has a shorter drying time - 24 hours , is not absorbed so quickly, does not change color.

But products based on vegetable oils have a common disadvantage - lack of a hard film on the surface, which would protect against scratching and abrasion.

Moisture is important when applying the product. For wood, this indicator should be at least 15-18% , for air in the room where the work is performed - up to 80%. If the timber is made of oily wood, then the working surface is first degreased with white spirit. Apply the oil with a brush or lint-free cloth.

Excess oil is removed after half an hour, with a lint-free cloth.

Important When applying the coating, it is important to ensure that the oil is evenly distributed. Otherwise, dark spots may appear on the panels.

The oil can be tinted by adding color pigment. The coating is short-lived.

Once every 2-3 years it must be restored.

Waxes

Wax paints are another product that is widely used for decorating wooden panels, including false beams. They are made from natural wax or its artificial substitutes based on petroleum products - paraffin, ceresin.

Wax paints are applied to the surface without a primer. Use a brush or cloth for this.

Typically two treatments are required to achieve the required coating thickness.

When using wax paints on the coating does not form a pronounced film. The surface is matte, the difference with the "bare" wood is sometimes almost imperceptible. Paint waxes are presented for both indoor and outdoor use. They may contain a color scheme that drastically changes the color of the finishing material.

Features of painting imitation of timber

Advantages of wax paints:

  • formation of a thin protective layer;
  • closure of wood pores;
  • silky, matte sheen;
  • protection against dirt, moisture;
  • antistatic effect;
  • the ability to restore worn parts.

Help. To emphasize the structure of the wood, to make it more expressive, some manufacturers recommend using oils for the topcoat.

Popular products in this category:

  • Tikkurila Nostalgia;
  • Adler Legno-Wachs;
  • Watco satin wax and others.

The finished mixture is poured into a convenient container.

If the product is not used immediately, then place it in a dark place and store no longer than 6 months.

Help. The more oil in the composition, the more liquid the coating. Coloring pigments can be added to the composition.

Stain (stain)

This agent penetrates deeply into the structure of the wood, thereby emphasizing its pattern.

Unlike drying oil, it does not form a film, so the pores of the natural material remain open. Therefore, the surface in the second stage is usually varnished. There are two types of stains - water-based and organic-based. These funds are produced in liquid or powder form. The disadvantage of stain is that it does not hide surface defects.

At the same time, it allows you to even out the color of the wood.

Azure

Azure - a coating that is increasingly used when working with wood materials ... It is also a transparent material, leaving the texture of a false beam open to the eye.

It is an analogue of varnish, but with a lower opacity.

Benefits of glazes:

  • allows the wood to breathe, so the moisture stored inside evaporates easily;
  • covering quickly and easily restored;
  • does not flake off like some paints.

Lapis lazuli are water-based and solvent-based, transparent or colored. Some manufacturers include biocides - substances that prevent the growth of mold and mildew.

It is noteworthy that products without biocides better protect wood from moisture , ultraviolet radiation.

However, in this case, it is better to additionally use special anti-fungal impregnations.

Table 1. Types of azure by coating thickness.

View Coating thickness, μm Application site
Thin Layer Up to 20 μm Does not form a film, but only saturates. Place of application - plank sheathing, fences, other elements subject to deformation.

The coating needs frequent renewal in order to fully protect the wood from adverse conditions

Medium layer 20-60 μm Suitable for elements with moderate deformation
Thick From 60 microns Does not penetrate deeply, but forms a film on the surface, resembles a varnish coating. It is used for doors, windows, other structural elements that do not deform

Attention! Do not use glazes if the air temperature is below 12 ° C.

Aqualak

The difference between this type of coating from the rest is a hard protective film, which protects the material from moisture penetration. But, unlike other types of varnishes, this product is made on a water basis, it contains acrylic. Therefore, the product is often used for interior work, since it does not emit an unpleasant odor.

Pure water is used for breeding.

The product may contain a coloring pigment, making the base even more attractive. In this case, the texture of the wood is visible through the coating. At the same time, the coating protects the material from decay, fungi, mold. The paintwork material dries quickly, so several layers can be applied within a day.

Important! Aqualak is not recommended for use on structural elements of a building that are subject to severe wear.

One of the few disadvantages is high speed of work. If painting is done slowly, stains may appear due to uneven coating.

The following manufacturers of paints and varnishes have such products

  • Rolax;
  • Tricolor;
  • "Rogneda" and others.

Acrylic coatings

Acrylic paints are actively used in European countries.

They are also water based and water soluble. These are fairly resistant coatings, which include:

  • plasticizers - give elasticity to the product, do not crack;
  • hardeners - speed up the process film formation;
  • matting components - eliminate glossy shine.

The advantages of such acrylic coatings include:

  • environmental safety;
  • no unpleasant odor;
  • vapor permeability ;
  • resistance to fading;
  • rich color palette;
  • protection against moisture.

One of the advantages of acrylic paints is a wide range of colors and shades

The coating dries in 5-30 hours.

Acrylate paints are used for both external and internal work.

Painting is carried out every 3-4 years. This type of paintwork material is contained in the brand lines:

  • " Drevoplast";
  • "Extra";
  • "Yaroslavl paints";
  • Pinotex ultra;
  • Tikkurila Pika-Teho;
  • Dufa.

Latex paints

Latex paints are also water-soluble and contain rubber (latex) in their composition. The coating forms a strong film on the surface, but at the same time it allows air to pass through perfectly, thereby prolonging the life of the timber. They do not emit a strong odor, therefore they are used both indoors and on the facades of the building.

One of the significant advantages of the product is fast drying (from 20 minutes). Latex paints are also notable for the fact that they can be applied even to absolutely smooth plastic.

Latex paints are plastic

Despite the versatility of coatings, it is important to pay attention to what parts of a structural element, they are intended, since the concentration of rubber in the composition depends on it. So, it is least of all in paints for ceilings, more in products for walls, and the highest percentage is in products for facades.

How to paint wood correctly

When painting work, it is important to fulfill certain requirements. In this case, the coating will be of high quality and durable.

The old surface is pre-cleaned of old coatings and cleaned with a sanding cloth, and then the dust is carefully removed.

Before applying the decorative coating, the surfaces are treated with fire retardants and antiseptics, which protect the surface of the false beam from fungus and mold. If mold has already formed, bleach is used first.

The coating lasts longer if the paint manufacturer's recommendations are followed

When using several products at the same time - for example, stain and varnish, you need to make sure they are compatible.Otherwise, the finish will be damaged. You also need to wait until the previous layer dries.

It is better to use a primer before applying paintwork material. Usually, the manufacturer indicates this requirement in the instructions for paintwork materials, and also gives recommendations as to which product is best suited.

This not only improves adhesion to the surface of the timber, but also reduces material consumption.

Painting is performed at an air temperature not lower than 5 ° C. If the work is performed outdoors, there should be no precipitation. The surface of the trimmer must be dry.
