The polymer cement waterproof paint is JS waterproof paint for short, J refers to polymer, S refers to cement, so JS is polymer cement waterproof paint. The polymer cement waterproof paint is an organic liquid material composed of polymer emulsion such as polyacrylate emulsion, ethylene-vinyl acetate copolymer emulsion and various additives.
The quality of the polymer cement paint is greatly influenced by construction environment, air temperature and humidity after the coating, the surface of the coating is quickly formed into a film, the film forming thickness is thinner, the surface strength of the coating is lower, the bottom of the coating is slow in drying and curing speed, and the cement can generate hydration in the drying and curing process to generate the phenomenon of volume shrinkage, so that when the coating thickness is larger, the surface of the coating is cracked in the process of drying to form a coating film. The constructor often needs to coat a thinner layer each time, and after the thin coating dries out, the constructor covers a layer again and repeats three to four times, and the construction process is tedious and the construction time is long. In the air-dried area, the water in the coating gradually evaporates, so that the volume of the coating is reduced, and the drying crack occurs, so that the service life of the coating is short.
