The second coat is applied as the first. High-quality color hold only glue and casein compositions. Casein primer before use to filter. Cause of its spray gun. Cement formulations should be coated with a high porosity. Particularly strong film is obtained by staining on porous concrete.
Prepared in the usual way the surface before applying the primer (first color) should be drench with water to a moisture content 37-40%. Primer is applied immediately after the disappearance of the surface water. Cement primer composition can be applied by spray gun or spray gun with nozzle diameter of not less than 2,5 mm. However, best results are obtained when applying the primer stiff brush. When painting internal surfaces of waterborne emulsion paints the surface being prepared in the same way as a conventional water stains. Apply paint by vitriol and alum soil is not recommended, so cooked ground surface primer corresponding color: polyvinyl acetate, stirolbutadieno-hand, acrylic, etc. When working on an oil ground surface must be proshpaklevat putty appropriate form of coloring. Priming emulsion formulations are applied by roller or paint sprayer.
Apply the primer with a brush is not recommended, because the paint loses its properties under a long feather. For small scope of work as an exception may be applied manually priming compositions bast primaries or tassels. In this case, the layer of primer on the walls causing vertical movements of the brush, followed by shading it in horizontal direction, the ceiling – the motion is parallel to the incident light, with the final shading in the transverse direction.
