Hydrastop Pro is a professional coating for stone and concrete. It makes all facades, walls, pavement and masonry work water repellent and waterproof.
An innovative and simple to apply solution, Hydrastop Pro is the ultimate protection against the harmful effects of exposure to the elements.
The hydrophobic properties creates an excellent beading effect, which makes the water bead off of the treated surface. This prevents that microorganisms can take hold onto the surface.
