Pentra®-Finish (HG)

Advanced High-gloss Stain
and Wear Protection Finish

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 water-based, lithium fortified chemical treatment dries quickly to a clear, extremely hard, micro-coating that tenaciously bonds and reacts with the substrate forming an insoluble bond.

Pentra®-Finish (HG) is a high-gloss, fast-drying lithium sealer that creates a microfilm on polished concrete, stone, terrazzo, masonry and other cementitious surfaces. This easy-to-use finish increases shine, enhances color and improves resistance against abrasion and stains. Pentra®-Finish (HG) generally increases the coefficient of friction on polished surfaces. This non-toxic solution is ideal for integrally colored, dyed and stained polished concrete and is VOC compliant.

Innovating for polished concrete

In 2004, Convergent Concrete introduced the first ever reactive densifier and micro-coating that chemically attached to the surface. This super hard, micro-thin film was pivotal in bringing polished concrete into the mainstream by imparting stain and wear production and increasing the gloss of the surface.

The final finish that lasts longer

Pentra-Finish (HG) stands above all other “guard” products both in performance and ease of application. It’s easier to use, provides higher gloss, better clarity, and offers greater durability than any other guard on the market.
