Coval's New Polished Concrete Sealer Protects Against Acid and Stains
Coval Technologies launched Coval Polished Concrete Sealer (PCS) that protects against acid etching, moisture, and stain damage without changing the natural sheen of the substrate. It has shown excellent performance in warehouses, retail and event spaces.
ASTM D-3363 test results demonstrate that Coval PCS has the highest hardness on the pencil scale of 9H, and in ASTM D-4060 Taber abrasion tests after 1,000 cycles, product removal was less than 1 mg. It resists citric acid and balsamic vinegar for 12 hours; coffee, tea, and wine for 48 hours, with removal by a dry cloth, and spray paint and permanent marker graffiti can be removed with acetone over 48 hours later.
