How is concrete sealed?
Refer to “Sealing the Concrete” on pages 143-147 of Concrete Countertops. Note, however, that while the book states that we use penetrating sealers (and at the time of its printing we were), we now use a “hybrid” topical sealer that also has penetrating qualities. Our CHENG Sealer is the sealer we actually use in our shop and is the best all around sealer for use with the concrete countertops we produce and for the products we sell for others to create concrete countertops. CHENG Sealer is a professional-grade sealer created from the latest water-based acrylic micro-emulsion technology which creates non-yellowing barrier coat to seal, protect and beautify concrete (thus, it is “topical” but is not a wet-look sealer). Particularly on porous substrates (like ground concrete), the sealer will deeply penetrate and provide years of protective service for your countertop. Our CHENG Sealer is intended to be used in conjunction with our CHENG Concrete Countertop Wax for additional protection.
