Protect your concrete and masonry from damage with the DriveHard 5-gallon Premium Concrete Weatherproofer and Fortifier. DriveHard penetrates into the surface; it creates a chemical bond that permanently increases the lifespan of concrete by preventing damage from many common problems, including extreme weather conditions (e.g. repeated freeze-thaw cycles). The patent-pending, water-based nano-silicone/silicate based formula creates a breathable, yet stronger water-repellant surface that is more resistant to abrasion and water dissolved salts (alkali). DriveHard also helps create a strong, natural-looking surface that resists UV and mildew damage to promote lasting performance. For your convenience, DriveHard can be quickly and easily applied with a brush.
