We would like to apply a clear acrylic sealer over colored concrete in an interior application. The owners cannot tolerate any solvent odor. Please provide a product recommendation.
We recommend the application of Sparkl-Seal E. Sparkl-Seal E is a transparent, water based, methyl methacrylate acrylic sealer. It has essentially no odor, and the water based formulation means it can safely be used in an occupied interior application.
For protection and a high gloss, “wet look” finish that enhances the color of stamped concrete, use Nox-Crete’s Sparkl-Seal. Sparkl-Seal is a high solids, non-yellowing, methyl methacrylate acrylic sealer that resists surface oxidation from the sun and chemical pollutants in the air. In addition, Sparkl-Seal has good water vapor permeability properties which allow the coating to breathe, reducing the risk for surface delamination or blistering.
A clear sealer which turns frosty white in color has delaminated from the concrete surface. This is most likely due to the coating's inability to release water vapor trapped within the concrete quickly enough to prevent pressure buildup beneath the coating. To prevent this problem, use a clear acrylic sealer offering improved water vapor permeability. We recommend Sparkl-Seal or water based Sparkl-Seal E in exterior coating applications that are subject to high moisture content.
To remove the existing delaminated or white decorative sealer, use Nox-Crete's Deco-Strip. Deco-Strip is sprayed or rolled onto stamped or textured concrete where it quickly softens and lifts worn out acrylic sealers. The acrylic sealer is then easily removed with a pressure washer or garden hose equipped with a spray nozzle, restoring concrete back to its original unsealed condition. Deco-Strip's fast acting formula quickly softens most decorative sealers and coatings in 40 minutes or less and can be disposed through municipal water.
