AFM WaterShield is a non-toxic clear topical sealer that will bond well to concrete. However, it does not have much abrasion resistance and therefore is not recommended for a concrete countertop. A better option would be our AFM Polyureseal EXT which is an exterior grade polyurethane with ultra low (9 g/l) VOCs. It has excellent abrasion and moisture resistance. It is, however, not edible, so cutting should be done on a cutting board. Four coats is recommended for a countertop. Samples are available on our website.Please read surface preparation instructions carefully. https://www.greenbuildingsupply.com/core/media/media.nl?id=1067063&c=772072&h=7
