The causes, preventive measures, and solutions to the poor plumpness of the epoxy floor coating are as follows:
Causes of Prevention and Control Methods The use of highly polymerized paint-based paints has a poor fullness. In paint formulations, attention should be paid to the selection of the resin binder. Pigment content is low or the paint is too thin. Use a paint with a higher solid content for coating the surface of the coating. Not smooth, the substrate absorbs large amounts of oil and improves the roughness of the surface to be coated. The sealer primer is used to eliminate the absorption of the coating on the surface of the substrate.
