Top coat is a kind of liquid transparent glue, which needs to be diluted with water during construction. This product can be used for wallpaper coatings, building exterior walls, wood products and other surfaces. It has the effects of dust prevention, dirt resistance and scrubbing resistance. So the top coat is also called dust-proof paint.
In order to save costs, some construction sites only spray primer and real stone paint, not topcoat. At that time, you may not see the difference, but after a long time, the difference between a decorated exterior wall and a non-decorated exterior wall is obvious.
In particular, friends who pursue good construction effect and stable quality of real stone paint must spray topcoat. If there is no topcoat, it is easy to cause the coating of real stone paint to be waterproof, white and easy to stain, thus shortening the service life of real stone paint.
