Pentra-Finish™ (LG) is a patented, satin, 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™ (LG).

Pentra-Guard™ (EXT) exterior surface hardening and protective clear coat is specifically designed for protecting exterior hardscapes installations from unwanted effects of water and oil penetration, salt efflorescence, and/or dirt and grime build which up can easily distract and diminish their beauty. Pentra-Guard™ (EXT) is a clear “Inorganic/organic Nano-Lithium® micro-film that hardens, seals, and protects against moisture damage to enhance the natural color of exposed aggregate such as paver, bricks, stones and/or decorative exterior concrete such as stamped, colored and acid stained applications. The unique treatment is extremely low in VOC’s (less than 50 grams per liter), environmentally friendly and has a very low polymer/ammonia odor. Whether your surface must tolerate significant foot traffic, abrasion, or chemicals, our advanced, versatile, exterior treatment offers high durability and bond strength; resists staining and dusting and withstands - UV, abrasion, chemical spills

Pentra-Sil® (AC) Advanced Lithium Alkalinity Control Formula Primer is specifically designed for use on sweating or efflorescing floors as a pretreatment for Pentra-Sil. The unique treatment will neutralize substrate surfaces suffering from alkalinity problems. It reduces sweating of the concrete surface, neutralizes surfaces treated with sodium or potassium silicates and reduces vapor drive that carries the alkaline salts to the surface of the concrete. High pH levels at the surface of concrete can attract moisture as Mother Nature acts to equalize an existing pH imbalance by drawing moisture from the concrete slab towards the surface or from the air above the slab. Reduction of this phenomenon has been seen through the use of Pentra-Sil® (AC) and Pentra-Sil® (C&N). It is aggressively worked into the pre-cleaned surface where it is allowed to penetrate deep into the substrate to control surface alkalinity.

Pentra-Sil® (C&N) cleans and neutralizes concrete that suffers from efflorescence, sweating, and other alkalinity problems. Pentra-Sil®(C&N) Lithium fixer for Concrete Efflorescence and Sweating Problems works by infusing lithium ions into the substrate—these ions calm alkali reactions between aggregate and Portland cement thereby reducing the formation of alkali salts and sweating. (For serious problems we recommend a full treatment of Pentra-Sil® (C&N), Pentra-Sil® AC), and Pentra-Sil®(HD). Pentra-Sil®(C&N is also excellent for cleaning concrete after diamond polishing.Pentra-Sil®(C&N) removes fine particles and dust that can reduce shine.

Pentra-Shield™ is a clear, penetrating, breathable, surface applied liquid that strengthens, protects and hardens concrete and masonry surfaces. Pentra- Shield™ Anti-scale treatment helps protect concrete sidewalks, driveways and other concrete and masonry 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-Melt™ is an industrial-strength ice melt formula with a very low freeze point -80ºF (-62ºC). Many ice melts work well down to freezing, but below that their effectiveness diminishes and ice can quickly re-form. Pentra-Melt™ penetrates ice on contact, making it separate from the substrate and allowing for easier removal. This low freezing point also means a single application can last from 48- 72 hours as the formulation resists dilution and refreezing. Pentra-Melt™ is easy to handle, requires no agitation and is safe for concrete and the environment.

Now you can beautify and protect surfaces in severe, environments thatrequire superior durability (abrasion/impact resistance, chemical resistance and superior bond-strength) with lasting aesthetics. Our inorganic, low V.O.C. heavy duty floor coatings are engineered to outwear and outlast traditional coatings such as epoxies and urethanes, modified acrylics and latex paints

Pentra Color™ Hard is a specially designed for painting and surface treatment for use on interior industrial and commercial applications, it comes in ten standard colors. However, the product is also highly useful on large public areas and surfaces, including floors in industry halls with one of the previously mentioned surface coatings. Pentra Color Hard™ is based on Nano technology using Crosslinking Resins and UV-stable pigments. Pentra Color Hard offers durability, quality and fast installation - that means lasting protection while minimizing losses due to downtime.

Pentra™-Protective Coating (PPC) is a Hybrid Inorganic / Organic Nano-Lithium® Topcoat Finish & Surface Hardener. This high solid, high performance quick drying, breathable coating is designed for use as both an interior and/or exterior industrial application and comes in standard colors – white, gray and green. The unique treatment is extremely low in VOC’s (less than 50 grams per liter), environmentally friendly (Green Leaf and can qualify for LEED points) and has a very low polymer odor.

Industrial Penetrating Colored Stain and High-gloss Surface Hardener is a polishable concrete color that gives the benefits of a penetrating hardener/densifier in addition to superior resistance to abrasion and dusting. When the surface is finish with Pentra Guard HP, Pentra Stain HG creates a durable, light-reflective surface that is easy to clean and maintain. This revolutionary new color and technic exceed all the systems in position at the moment.
