PROSEAL SL is an engineered emulsion specially formulated for providing water repellency and stain resistance effect on a variety of mineral-based surfaces. The low viscosity allows it to penetrate the surfaces and reduces the capillary absorption, which gives a water repellency effect without altering the look. The product can be sprayable as well as brush/roller applied. Minimize the growth of algae and moss and accentuate the character of the concrete.
