Coval Technologies Releases New Sealer with Excellent Testing Results
Coval Technologies has released a new polished concrete sealer (PCS).The distinguishing characteristic of the sealer is that it protects against acid etching, moisture, and stain damage without changing the natural sheen of the substrate.
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 1000 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.
