PENTRA-HARD Finish is a patented, high-gloss, stain and wear resistant finish for improving the sheen, hardness and chemical resistance of conventional concrete, hardened concrete and/or cement based floors. This water-based, lithium-fortified (chemical polish) quickly dries to a clear, extremely hard, micro-coating that tenaciously bonds and reacts with the substrate forming an insoluble bond with the surface. Formulated using SiRE(™) Silicon Reactive Lithium Hybrid Polymer technology for extreme gloss, rapid shine development and excellent wear properties, this novel treatment eliminates the need for floor waxes, liquid polishes and conventional resin based coatings. Best results and coverage will be obtained by densifying the surface with PENTRA-HARD Densifier before applying PENTRA-HARD Finish.

Because of its unique chemistry, PENTRA-HARD Finish will not lift or peel from the surface. Periodic recoating requires no stripping as the material doesn’t build up.

The easy-to-use finish is tough, mark-resistant, fast drying and non-streaking. The treatment is used in conjunction with a high speed burnisher on non-porous concrete surfaces to provide superior clarity and improved resistance against water and water-borne stains from accidental spills, oils, dirt and grime.

Ideal for standard, ground, honed or polished concrete, integrally colored, dyed and/or stained concrete. (Use PENTRA-HARD Finish in conjunction with PENTRA-HARD Densifier application as part of the Durable Floor System™ (DFS) or on previously densified, polished or hard (power) trowelled surfaces. PENTRA-HARD Finish enhances the color intensity of integrally colored, dyed, or acid stained concrete, reducing efflorescence and mineral deposits and maximizes light reflectance.
