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…
LIQUI-HARD Concrete Densifier & Chemical Hardener
LIQUI-HARD is a proprietary, water-based, ready-to-use, clear silicate liquid concrete densifier and chemical hardener. LIQUI-HARD is formulated with chemically reactive raw materials to harden and dustproof concrete.

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…

Waterproofing Systems for Plaza Decks
W. R. Meadows’ Wendy Talarico, LEED AP, Architectural Services Specialist, explores the waterproofing world of plaza decks in an article published in The Construction Specifier. Plaza decks involve a variety of sizes, shapes and surfaces, resulting in confusion about the best way to waterproof them. “A plaza deck is a layer-cake of materials: the waterproofing membrane provides the base layer and the rest—protection layer, drainage course, insulation (or sometimes a fill layer of sand or gravel), and wearing or traffic surface—is ‘overburden.’ How those layers are designed depends partially on the design of the slab itself, which, in turn, depends…
