Discussion

SILICONE WATER REPELLANT is an invisible, deep penetrating, weather resistant, water and dirt repellent, which seals brick, stone, concrete and mortar surfaces against penetrating rain, water from garden irrigation systems, taps or down pipes. On any porous, such as pre-cast concrete walls, SILICONE WATER REPELLANT will prevent algae growth and subsequent discoloration.  SILICONE WATER REPELLANT is available in 25L and 5L containers.
