Sika Water Repel+ is a water repellent and barrier for concrete, brick, stone, and masonry that is solvent-free. It repels rainwater without altering the cosmetic appearance of the substrate, penetrating deep into the treated region and providing efficient water repellency for several years. It has stronger water beading and is resistant to ultraviolet radiation. It can be used on all types of masonry surfaces, including concrete, brick, and stone, that are both absorbent and dry, to provide an efficient, protective layer against rainwater penetration.
