Pentra-Cure™ (PW) is a high performance non-ionic water-based paraffin wax curing compound designed to give superior resistance to water retention for newly freshly placed concrete. Pentra-CureTM (PW) forms a tight covering film which reduces too early evaporation of water in concrete. Pentra®Cure is easy to apply, cost competitive and dries quickly.

The performance of a true cure, hardener and densifier in a single application.

Pentra-Sil® (H) is a premium lithium polysilicate hardener for fresh, newly- troweled concrete and tilt-up construction slabs. This fast-drying reactive formula provides maximum hardening to improve abrasion resistance and reduce dusting with a simple, one-coat application. Curing compounds can be applied directly on top of treated surfaces to enhance hydration without the discoloration and whitening associated with traditional hardeners.

Pentra-Sil® (NL) is a premium lithium polysilicate densifier for concrete surfaces. This high solids formula provides maximum hardening to improve abrasion resistance and reduce dusting. Easy, one-coat application. No water rinse required. Can be applied on fresh, newly toweled concrete and tilt-up construction slabs.

Pentra-Sil® (HDS) is specifically formulated penetrating hardener, densifier and sealer for colored, dyed or acid stained concrete and terrazzo surfaces. Ideal for the grinding and polishing process of integrally colored, dyed or acidstained concrete. With color shielding and efflorescence control, this unique densifier substantially enhances the color depth, increases the abrasion and protects against water and/or other contaminants.

Pentra-Sil® (244+) is a premium hardener, densifier and sealer with hydrophobic properties ideal for protecting concrete and masonry surfaces against the damage of wind-driven rain, freeze-thaw, moisture, and chloride ion intrusion. Pentra-Sil® (244+) combines the benefits of lithium silicate densification with reactive silicone chemistry to meet the NCHRP 244 standard for chloride protection of concrete in a single application. The reactive treatment reduces permeability, helps prevent efflorescence leaching and provides chloride ion resistance to deter reinforcing steel corrosion and spalling. When sprayed on new or existing concrete, it penetrates where it reacts with free calcium to form insoluble calcium silica hydrate, which makes concrete more water, stain, and abrasion resistant for easier maintenance and longer life.

Pentra-Sil® (IH) impregnating hardener is a penetrating Nano-Lithium® treatment for terrazzo, stone, and polished concrete surfaces formulated specifically for surfaces that will be ground and polished. Pentra-Sil® (IH) is ideal for restoring and polishing worn and damaged surfaces. This environmentally friendly treatment also reduces alkalinity (efflorescence), improves overall abrasion resistance and reduces dusting. Its deep-penetrating, non-soluble characteristics provide longer life and higher reflectivity, helping reduce floor maintenance cost.

Pentra-Guard (HP)™ is the optimum coating system designed for harsh and high abuse conditions. If your surface must tolerate foot traffic, large equipment, abrasion, or chemicals, our advanced, versatile, low VOC treatment offers high durability and bond strength; and the ability to withstand UV, abrasion, chemical spills and heavy traffic. This Industrial Grade Treatment provides rapid curing and attractive, glossy finish for facilities that require maximum protection and little-to-no downtime

PENTRA-GUARD® (HPS)Advanced High Gloss, Stain and Wear Protection Finish is Designed for Non-porous, Highly polished Surfaces Concrete, Finished Stone & Terrazzo (1500 grit profiles and above)

Pentra-Finish™ (HG) is a patented, high-gloss, stain and wear resistant finish for improving the sheen, hardness and chemical resistance of natural and cast stone, terrazzo, masonry, and other cement-based surfaces. This waterbased, lithium fortified chemical polish dries quickly to a clear, extremely hard, microcoating that tenaciously bonds and reacts with the substrate forming an insoluble bond. Formulated using reactive silicon hybrid polymer technology (SiRE)™ 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 approved Nano-Lithium® Densifier before applying Pentra-Finish™(HG).
