Coval Multi Purpose Sealer is a general purpose sealer, incorporating many of the advantages of Coval’s nano/ covalent technologies in one product. Multi Purpose Sealer creates a water resistant, but breathable surface layer in all kinds of porous materials, such as concrete, natural stone, fabric, etc. Surfaces become highly stain, humidity, UV, abrasion and graffiti resistant. This is an environmentally friendly product with zero VOCs.
Coval Multi Purpose Sealer may also be used as a primer or pre-coat for other Coval products.
Test: As with all Coval products, it is recommended to test for compatibility in a small area, before full application.
Surfaces must be clean, dry and in sound condition. Remove all oil, dust, grease, dirt, loose rust and other foreign material; including all existing silicon sealers. Use Coval Step#1 Cleaner for Unpainted Surfaces. Stir carefully, both before and during application, to fully suspend particles. Mask off all areas not to be covered. Apply an even flood coat, either with a pump (deck) sprayer or by pouring; back-roll with a 3/8” nap roller, to ensure even coverage. This product requires two or more coats; re-apply wet-on-wet within 15 minutes, and repeat until surfaces are saturated. Clean-up immediately with acetone.
Note:All equipment must be chemical and acetone resistant.
Caution: A professional spray mask should be used with this product, as well as eye protection, rubber gloves, and coveralls.
