It can also act as temporary surfaceimmersion seal to realize antifouling, dustproof and good maintenance performance. Solventfree, white synthetic dispersed resin. Fast drying after coating, prevents selflevelling cementbased materials generating surface bubbles caused by air entering capillary pores during cementbased waterproof material solidification.
