surface staining - a rather delicate procedure that requires thorough preparation and strict observance of technology works.
The paint must meet the base type (concrete, wood, metal, etc.) and applied to a pre puttied and primed surface. Staining occurs in 2 - 3 layers, which are applied to each other only after complete drying.
The paint layer must be optimal thickness if it is too thin, it will occur bald spots and smudges, and if too thick, it is possible a number of negative consequences.
Major defects occurring when staining too thick paint:
- paint cracked - occurs on the surface of a plurality of short, narrow cracks which intersect each other and form a pattern similar to crocodile skin;
- surface wrinkling - colored base when dry as it shrinks, it happens as a result, the upper layer coating dries in several times faster than the lower;
- Foaming paints - it appears on the surface of a plurality of small bubbles which burst and form minute pores;
- Peeling the base - ink is first formed on the cracks network, and then it begins to peel off from the wall and keep small pieces.
How to solve a problem
To solve the problems arising from the application of a thick layer of paint, perform the following steps:
- Clean the surface - a base on which the defect is manifested completely cleaned of paint with a scraper or spatula and the paint solvent.
Important! If the problem affected a small area, it is allowed to sweep point, and if the defect has spread over a large area, it is best to remove the paint completely and paint the surface again.
- Prepare for priming - carefully handle base with sandpaper, remove dust and dirt, oil stains and putty if necessary;
- Priming - with brush or roll coat of solution and leave to dry.
Important! The primer must be carefully selected according to the base type.
- Dyeing - after surface prepared and dried completely new applied ink layer, after complete drying, if required, apply the second coating layer.
