To give aesthetic appearance to wooden panels, they are usually painted or coated with various decorative compositions. But to apply an even layer of fresh paint is impossible without removing the old coating. This is done in various ways, but you have to work hard.
The most common way to clean wood from old paint is to sand it with sandpaper. In this case, you can use the manual method or use a grinder. First, the surface is treated with sandpaper with large grain. In the process, sandpaper is quickly clogged with paint residues, so use a special cleaning pencil to clean it.
Since coarse abrasive grain leaves deep risks on the surface of the wood, after removing the paint, it must be sanded with fine sandpaper. The cleaned surface is vacuumed and primed.
The next method of processing wood panels is to heat and mechanically remove old paint. For work using a building hair dryer, putty knife and spray with water. Heated the surface with a hairdryer until bubbles appear, tear off the paint with a spatula. If during heating, the paint ignites, use a spray gun to eliminate the fire. The cleaned wood is ground and primed.
Old paint can also be removed using chemicals called rinses. They are sold at any hardware store and are packaged in cans, cans or aerosol cans. Before purchasing the product, you should read the instructions for use, since not all compounds can be used on wooden surfaces.
Any wash, with the exception of aerosol, is applied to old paint with a brush or roller. In this case, it is necessary to wear safety glasses, gloves and protect the respiratory system. After processing, withstand a certain time specified in the instructions. After it expands, the paint softens and can be removed with a spatula, or other similar object. The cleaned wood surface is treated with a solvent to remove the remnants of the wash and neutralize its action.
The easiest way to remove old coatings is scraping, used for peeling paint, removing many of its layers or streaks. For these purposes, use a metal spatula, the edge of which is sharpened to the sharpness of the knife blade. The procedure must be performed with great care so as not to cause serious injury to yourself or others.
