Types of paint layers

Imitation finish

Stained wood transparent dyes. Painting - drawing on the surface of wood dyes, which do not obscure the texture, but on the contrary, increase her. It may be superficial and deep.

Surface color is most popular. The solution of the dye is applied to the surface details tampon, sponge and better spray gun (the latter method is called dry color). For coloring use aniline dyes and humic or their mixtures, dissolved in a soft, clean water, preferably in enamel or tinned vessel. Water soften a small amount of baking soda or ammonia and heated to a temperature of 35 .40 ° S.
When manually applying dye to gather brush, sponge or swab and uniformly lead them on a horizontal surface of wood. If the surface is vertically, then the dye is applied from the bottom up to avoid streaks formed. After 3-5 min after the paint surface is rubbed with a cloth well wrung or sponge to remove excess dye and uniform color surface.
It is better to apply wood stain to the surface by spraying with the spray gun, which lead uniformly at a distance of 250 - 300 mm from the surface and surface. The rational is the way to paint bare parts or products (legs, chairs) by immersing them in a bath with the appropriate dye.

Stain the wood can and using aqueous solutions of chemicals - salts, acids and tannins. As a result of chemicals in the wood or their interaction surface of wood painted in the appropriate color. Stained wood with chemicals called protravnim, and themselves chemicals-mordant.

Painted surface is dried and grind worn-grained sandpaper № 6-3, without much pressure on the edges and the edges of parts. If a little nap, then Sanding can be performed with a thick cloth or felt, as a superficial staining dye penetrates to a depth of 0,5 mm.

Deep color is used in cases where the timber should be painted on all its thickness. To do this it soak for several days in a solution dye. This way you can paint only thin sheets of veneer.

More common is the deep color of blanks in the autoclave

This way you can simulate harvesting birch walnut, mahogany and maple gray. For better penetration of the dye in the timber harvesting first steamed under pressure 1,5-0,2 MPa for AOR-45 min, then held in a vacuum - it helps to remove the bulk of air from the cells. After This condensate is produced, and the autoclave was filled with dye solution under pressure of 1 MPa to 6 MPa and billets for veneer. Leaks lasts 50 - 60 minutes at at 80 .90 ° C. After this, remove the pressure, the dye release, and the workpiece is unloaded, dried and passed for further processing.

The deep color of massive parts in an autoclave with capacity of 1 m lasts up to 4 h, veneer - up to 2,5 hours
Deeply colored wood can be carried out and on the tree during its growth, ie standing. Wood stain through the roots, trunk and branches. Most rational approach through the barrel, because dyes penetrate better in the vertical direction. To do this in the root of the tree, designed for painting, remove ring of bark. At this point, drill a hole, in which hoses, with tips flowing dye.

The most widely used color at the roots of beech wood, rich in tannins, interact with solutions of metal salts.

Surface and deep color may be direct and protravnoy, positive and negative.
Coloring simultaneously with lacquered colored varnish significantly reduces the manufacturing process of finishing, but it is not only veiled texture, but also reduces the decorative properties of wood. Therefore, it is recommended to use for parts to finish that do not make high demands.

For dying wood of different species, as well as to simulate wood dyes are used on the composition of the various solutions, they are preparing a 10% MI, and then diluted to the desired concentration. Desired amount of dye is stirred into soft water and heated to boiling, then cooled and filtered.
To dyes of various shades, you should prepare separate solutions of various dyes, and then mix them, selecting the desired color and shade. If in the preparation of solutions to change the ratio of pigments, some of these components can produce different shades. However, painted wood is very sensitive to acids and alkalis, and this may lead to irreparable marriage. For example, carbamide glue from solidifying ammonium chloride completely changes the color of the dye on the surface of wood.

Imitation wood grain airbrush method. Imitation wood transparent stains do not reproduce the texture of wood, but only intensifies the color. To play a completely new texture to the surface of wood or gain. Apply imitation wood way Decals. Depending the distance from the simulated surface-to airbrush them can cause fine lines and broad diffuse band. Speed airbrush during Work - 10-20 m / min. The way to airbrush you can play any figure, but the best simulated image to the wood, has a band texture (mahogany, walnut, rosewood). Reproduce airbrush complex texture (birchwood, etc.) almost impossible.

Imitation wood aerography may be opaque and translucent

When an opaque imitation of natural wood grain completely covered the background color of the soil, which is the simulation of the valuable timber. When applying the background airbrush is held at a distance of 150-200 mm, the velocity of its 15-20 m / min. For printing texture airbrush slowly moving at a distance of 10-15 mm from the surface of wood. For the simulation using the opaque enamel paints.

When simulating a translucent background is the natural color and texture of the simulated wood (this is important the correct selection of wood and dyes). Texture negruntovanoy applied to the surface in the direction of fibers of natural pattern.

Supplementary figure is applied so that the natural texture did not interrupt him, but rather complement and enrich. This requires not only skill, but also the artistic taste of the artist. Therefore, in the process of implementing the simulation must be before the eyes of samples of the simulated timber.
