Open the paint bucket, you should first carefully observe the paint surface is crusting, dry knot, precipitation, discoloration, thickening, turbidity, deterioration and other quality problems, such as alkyd resin coating due to the packaging is not tight and the surface skinning Should be exposed off the film, due to resin and salt pigment saponification of the dry can not be used, and the tin can not be discolored packaging should be replaced and treated before the line modulation. Viscosity of the factory coating should be higher than the viscosity of the coating, for some precipitation, before adding no diluent to use
