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 wet mop on hard-troweled concrete. Clean up materials that stain as soon as possible.

LIQUI-HARD may be reapplied if desired if the concrete is exhibiting any unusual wear. Before any LIQUI-HARD reapplication, put a small amount of water on the concrete surface and wait 30 seconds. If the water does not penetrate into the surface, reapplication is not recommended. If the water does penetrate into the surface, LIQUI-HARD may be reapplied. A small test application is always recommended before performing any full-scale application.
