HydraCrete WR is a water repellent coating that protects your concrete, brick, mortar & masonry from the damaging effects of water intrusion and delivers an durable, optically invisible high-performance penetrating sealer .It is a kind of protective shield against environmental influences and provides dirt and water repellency (lotus effect). The surface stays clean much longer and it is far easier to clean. Surfaces coated with HydraCrete Surface Protector gain a long lasting, perfect protection against influences. The UV-stability enables a long lasting protection of the coated surface, provided that it is not destroyed by abrasion.

Absorption of harmful substances, which may lead to the structural damage described above, is usually the outcome of contact between the building material and water. This is an example of capillary water absorption, and also occurs when splashes of water land on de-icing salt. Forming a hydrophobic zone greatly reduces the amount of water and harmful substances which are absorbed .Moreover, an unprotected concrete surface tends to absorb lots of water via its micro capillaries when water flows onto the surface thus leading to formation of micro-organism like algae fungus etc which hinder the look & aesthetics of the dwelling.The concrete’s pores remain open after water-repellent treatment, so that watervapor and gas diffusion are not measurably influenced. Thus, a concrete’s natural properties are retained, and even when the surface is damaged (crack formation) it remains adequately protected. As a result, the water-repellent treatment has a significantly longer service life. These are clear advantages over film-forming coatings, which easily flake off as they don’t allow water to pass out
