Keep LIQUI-HARD treated surfaces looking their best with our easy-to-follow maintenance guidelines
LIQUI-HARD concrete densifier and chemical hardener penetrates deep into the concrete being treated, leaving a residue-free surface. The hardened and dustproofed concrete requires similar maintenance compared to untreated substrates after LIQUI-HARD is applied. Simple sweeping or mopping daily or as needed on hand-troweled concrete is recommended. Once a week or when needed, hose the surface down with water. A soft sponge squeegee or a or a ride-on vacuum squeegee with a foam pad can be used to remove excess water. In areas that have gathered dirt, a mild, neutral pH detergent soap can be used with a bristle brush or…

5 Reasons Your Building Needs a Below-Slab Vapor Barrier
There is much debate over the role and merit (as well as need) for vapor barriers within varied sects of the construction industry—however, there is a simple truth no matter what side of the discussion you happen to find yourself on. Ultimately, the systems under your building and above the concrete slab need protection, too, and simply leaving HVAC systems, wiring and plumbing, or the framework itself exposed offers far too much room for error—and seriously tempts Murphy’s Law. There is no sense in leaving the fate of your building up to chance, because let’s face it—damage can occur above…
