Seal-Once Marine Waterproofer is the first non-toxic waterproofer. Formulated to withstand the harsh marine environment, it will last longer than other products due to it's ability to penetrate and become part of the masonry.
We recommend cleaning the surface prior to application for the longest life. We sell Seal-Once masonry and concrete cleaner.
