Enviroseal is a highly-effective, liquid based water repellent containing silicone emulsion for use above ground. It can be applied to multiple substrates, including porous brickwork, cement renderings, asbestos, cement or mineral boards, unglazed tiles, cast concrete, roughcast, stonework (including calcareous materials such as those containing limestone), wood, canvas and leather.
Surfaces treated with Enviroseal remain permeable to vapour so that moisture within the structure does not remain trapped.
Enviroseal is clear and colourless and will not normally alter the appearance of treated surfaces. In some cases, however, very slightly darkening may occur, so a small test area should be applied when appearance is critical.
Depending upon the nature of the surface treated and conditions of exposure, two coats of Enviroseal can be effective for at least 10 years.
