The excessive amount of concrete curing agent in epoxy floor paint makes the film brittle and hard, the improper amount of catalyst makes the film brittle, or the base material is not thoroughly degreased and dedusted, so that the base material is contaminated with grease and dust, which is the reason for the poor adhesion of the paint film. After the construction of PU floor paint, the time of placing is too long, the old paint has not been polished and cleaned, or there are too many silicon additives in the bottom layer, resulting in poor adhesion between coatings and even peeling after re-coating of epoxy floor paint.
In order to prevent the poor adhesion of epoxy floor paint and overcome the peeling phenomenon between coatings, it is necessary to strictly control the proportion of concrete curing agent, control the amount of catalyst, thoroughly remove the grease stain on the coated base material, clean the surface of the old coatings or coatings that have been put on shelf for too long, and polish the surface of the coatings smoothly and then coat it again. New epoxy floor paint. In order to re-coat the paint, it is necessary to select re-coatable auxiliaries (especially silicon-containing auxiliaries) and strictly control the amount of additives. The epoxy floor paint film with poor adhesion has been formed. It is necessary to remove it, re-clean the base material, properly mix the paint in proportion and re-coat it.
