The causes of floor surface brush marks:
A, the construction: construction method error, coating construction time is too long, after mixing uniform roller, coating and its thickness control does not reach the designated position.
B, tool reason: quality unqualified roller, roller surface treatment is wrong.
C, the cause of the coating itself: mainly poor flowing property of paint, paint viscosity is too high. Has thixotropy fillers or additives.
A, pay attention to the construction methods, coating curing time not too long. The two end of the cylinder to the rounded corners, coating thickness again as far as possible do not less than 0.15 mm.
B, bought a bit of roller, roller tape with the roller surface before using
C, coating, increase the coating flow property, lower the viscosity of the coating, minimize has thixotropy fillers and additives, special attention should be paid to metope paint flow ping agent on the phenomenon of floor coating.
