Particles appear on the paint surface, which is as rough as sandpaper, which not only affects the brightness of the surface, but also affects its appearance. The reasons are as follows:
(1) Raw lacquer contains paint slag, or if it has been stored for too long and has fine skin and impurities mixed in, and it has not been filtered before construction, the paint film will have particles and cause roughness.
(2) The construction site is not clean, and impurities such as lime sand, yarn wool, and dandruff are stained on the topcoat.
(3) There are dust, sand, and paint on the paint brush, which are not cleaned and brought to the top coat.
(4) Forget to repair the edge of the paint flow, so it is easy to dry and form a skin. If you are not careful, put the paint belt into the paint liquid to paint.
(5) Sometimes due to the sudden change of weather during construction, the topcoat dries faster, and the paint film begins to conjunctival before brushing, and the broken paint film fragments accidentally brushed into the brushed paint film, will result in a rough surface.
