Even a beginner in construction or repair workknows that if the paint is applied to an unprepared surface, it will quickly warp, begin to flake off. Proper preparation is perhaps the most important condition for successful painting of any plane.
In order to extend the service life of the products, primers are designed. Today there are many of them:
If to classify primers by types of materials with which it is necessary to work, it is possible to allocate:
On sale today you can meet already ready forapplication formulations or dry mixtures, which must be diluted with water before use. Usually the composition of the primers, recommendations and the scope of their application are indicated on the packaging.
Impregnation for wood protective can be of two types:
In the first case, the primer for a tree mustit is necessary to include a special film-forming agent in the composition, but there should not be any dyes or pigments in it. It is usually applied to transparent varnishes, because it perfectly emphasizes the structure of natural wood.
When choosing such impregnations, it should be taken into account thatsubstances forming a film, are included in all primers. But in order to emphasize the beauty of natural fibers, it is worth giving preference to casein-rosin fillers. They do not cleave wood fibers, they do not mask the pattern that they form.
Before painting the surface in any opaque color for pre-impregnation, primer for wood (or universal), which corresponds to a specific paint, is more suitable.
Modern compounds for primers usually combine several qualities:
Primers for wood are used to impregnate previously painted, as well as new, not yet processed surfaces.
Before applying the primer, any (old ornew) surface must be cleaned well, remove the remains of the old coating, align. If there are cracks or other defects on the tree, they must first be removed with a putty. When it dries, the surface should be treated with ammonia solution for degreasing. Typically, for its preparation in a liter of water, dissolve a liter of twenty-five percent ammonia solution.
Primer for wood is applied on a flat, dry surface.
