Rainwater can be a wonderful thing, as long as it's kept outside. Whether you are looking to waterproof roofs, RV's, gutters, planters, foundations or much more, Liquid Rubber Waterproof Sealant will do the trick. It is a flexible heavy-duty multi-purpose coating that cures into a waterproof membrane. It stays soft, flexible and may have some tackiness, so is not meant as a walking surface. It provides excellent adhesion, chemical and UV resistance and is resistant to freeze/thaw cycles. Best of all, it is water based, meaning no harmful solvents or VOC's.
