Whats the difference between WaterShield and Penetrating WaterStop?
Safecoat WaterShield is a film forming sealer composed of a hydrophobic acrylic resin and emulsified silcone suspended in water. WaterShield reduces surface tension promoting water repellency on wood and masonry surfaces. Porous material may require multiple coats to obtain the desired protection. WaterShield dries clear and will slightly darken the surface. Safecoat Penetrating WaterStop is a penetrating type sealer composed of potassium silicate and a modified hydrophobic acrylic suspended in water and is designed to chemically bond with the salts and minerals in cementitious surfaces. Penetrating WaterStop is recommended for concrete, stone and lime or cement plasters. It dries clear and does not discolor the surface.
