Qingdao City, epoxy floor paint coating type and repair, according to the construction plan and construction experience, some Sheng chemical solution tank inner surface of the epoxy floor paint coating may be vinyl paint, epoxy or epoxy phenolic resin paint . Understand the characteristics of these three materials generally can be inferred that the actual use of the surface of the epoxy floor paint coating type. A very practical way to determine coating compatibility is cleaned half a square on the surface to be painted, together with proper surface preparation, and then coated refinish. More work done, it is possible to determine: A; epoxy floor paint coating is damaged old coating, causing swelling, dissolution or loss of adhesion;; whether the new coating on the old coating has enough adhesion. If not, usually after the new coating applicator full days, it can be peeled off from the old surface down, if not from the surface physical stripping knife cut a mouth, it will burst out from the surface, scattered, apparently old and new coating are incompatible. Integrated above; if the old and the new coating adhesion is good, the new coating greatly reduces the tendency of the old coating and the substrate surface adhesion. Down across the board, the entire coating tends to burst out from the base surface, scattered, it indicates that the adhesion of the old coating has been damaged, indicates that epoxy floor paint coating damage to happen in the near future. This test does not point out the specific type of residual epoxy floor paint coating, it can only measure the compatibility of the old and the new coating. If the test without the occurrence of the phenomenon, both coating compatibility, new finish can be satisfied with the restoration of the old coating.
