What are the common problems in the construction of epoxy floor? A series of problems often occur in the construction of epoxy floors. In the short time after the application of topcoat in heavy-duty anticorrosive floors, the topcoat film will automatically expand, shift, wrinkle, shrink, and air bubbles in departments and regions, and even make the bottom coat lose adhesion, and the base coat will be bitten off. Easy to bite the bottom, foaming coatings are: nitro paint, epoxy paint, polyurethane and other coatings containing strong solvents. 环氧地坪漆涂层的配套功能不和，底漆以及面漆不配套。涂层未干透就涂装下一道涂料。如过氯乙烯磁漆或清漆未干透，加涂第二道涂料。在涂装面漆或下道漆时，选用过强的稀释剂，将底层涂料溶胀。
The functions of epoxy floor coatings are not compatible with primers and topcoat. The next coating is applied when the coating is not dry. If the perchloroethylene enamel or varnish is not dry, add second coatings. When coating topcoat or undercoat, use excessive diluent to dilate the bottom coating.
If there are such problems, we must find ways to prevent them. Strictly follow the paint instructions for painting. Usually the same kind of paint can match each other. Differential types of coatings matching selection of the principle of hard and soft; epoxy floor paint paint paint coating selection of the diluent can not exceed 5% of the total paint, the type of coating process should be unchanged, can not use weak polar diluent at the bottom, the upper coatings use strong polar solvents, such as acetone, esters and high boiling point aromatic solvents.
The paint must be dry and comply with the best painting gap and must reach the shortest painting clearance. During winter construction, the coating gap can be appropriately elongated, and the bottom coating can be guaranteed.
Epoxy floor paint to prevent biting, the first should be coated thinner, after completely dry and then coated with the second coating, can not be too thick once coated, so that the solvent can not volatile inside, extend the dry time. The paint that produces the "bottom biting" problem can no longer play the role of guarding and dressing. The coating on the bottom should be removed. Patch and improve matching. If the primer is not dry, finish the primer before finishing it.
