Our Invisible Waterproof Agent contains pure acrylic emulsion, liquid thickener and film forming agent. It can repair cracked surfaces, solve water leaks, and provide a long-lasting seal repair that will make your walls look like new walls for years to come. Its use is very simple: squeeze the waterproof glue to the surface of the required tiles and other workpieces, brush evenly, and wait for 5-10 minutes. It can effectively plug the leak and make the water drop float on the surface, so as to achieve the waterproof effect layer.
