11/21/2023 0 Comments Staining cinder blocks![]() We only had 3½ weeks, so we didn’t pull any punches, exposing the sealers to extreme testing procedures to see how well they held up.Ĭoncrete sealants meant for indoor use were not tested outside. ![]() Admittedly, concrete sealers are supposed to last a year or longer, and we didn’t have that much time to test. In addition to testing resistance to staining, we noted how well each sealer’s finish held up to freezing rain, ground-in sand, de-icing salts, mud, grease, and finally, power-washing. If it remained stained even after power-washing, it received 0 points. If it resisted stains moderately well, it got 2 points. For example, if a paver we’d treated with a sealer resisted oil and stains very well, we awarded it 4 points. For our testing purposes, we used a scale from 0 to 4, with 4 being the best. We extensively tested each concrete sealer and awarded points based on its performance.
