BEHR advertises their Premium Protector and Waterproofer product as a silicone waterproofer to penetrate and keep water out while shielding against corrosion and salt damage. However one of the types of concrete sealers we suggest staying away from is silicone based sealers. Claims that this product will penetrate are false since silicone based sealers are typically topical in nature they cannot penetrate the way a silicate does. One of the worst atttributes of a silicone sealer is their short life span. Lasting maybe a few months if you are lucky at the first signs of exposure to UV rays this product will start to deteriorate. Also surfaces become extremely slippery after using this product which cause more of a hassle than anything.
Our Take: No matter what BEHR claims it will not not waterproof concrete and masonry surfaces longterm. It may appear to hold up but at the first sign of water, since it is latex based, it will start to peel and flake off. You are better off using a penetrating solution to waterproof concrete since there is no risk of peeling and bubbling.
