PENTRA-HARD EDH is a clear, penetrating, breathable, surface-applied liquid that strengthens, protects and hardens concrete surfaces. PENTRA-HARD EDH anti-scale treatment helps protect concrete sidewalks, driveways and other concrete surfaces from freeze-thaw damage caused by moisture saturation within the pore structure of substrates. Scaling begins with the first freeze-thaw cycle and will continue through successive winter seasons resulting in repeated loss of the concrete surface, eventually leading to spalling, pop-outs and ultimately failure if left untreated.
PENTRA-HARD EDH penetrates the substrate, and chemically reacts with the free lime in the concrete. This chemical reaction will enhance the durability of the concrete and help prevent corrosion and deterioration from water, deicing chemicals, acid rain, and freeze-thaw cycles.
