Stain and Germ Resistant Impregnator/Sealer

New and Improved Formula with Antimicrobial Protection!

StainGuard-50 stops food and beverages from staining surfaces and contains an advanced biocide that inhibits the growth of bacteria, fungi, mold and mildew.  It is often used on natural stone like granite, marble and travertine, but it can also be used on concrete and other masonry building materials.

StainGuard-50 is an excellent treatment for a wide variety of applications, including but not limited to building facades, floors, walls, swimming pool surrounds, patios, garages, and entertainment areas. 

Treated indoor and outdoor areas become easier to clean and maintain resulting in long-term protection of the surface’s original aesthetic beauty.   

How It Works 

StainGuard-50 penetrates the surface and bonds chemically to the walls of the open pores as well as the surface of the substrate, stopping the ingress of water-borne and oil-based contaminants and resulting in long term hydro/oleophobic protection. StainGuard-50 also contains a multi-function biocide which inhibits the growth of common bacteria and fungi. It is designed to work without changing the natural appearance of the surface and never flakes or peals.
