How It Works

Flex Seal Liquid uses an inventive method to provide liquid rubber in a can. Once the liquid is applied to a surface, a chemical reaction begins which helps it solidify in its surrounding mould. The rubber once in its solid state will retain its shape and state against all forms of external pressure. Since it is in a liquid state, it can be poured, rolled, brushed or dipped in and the product will then take the desired shape. The rubber works much like water in the way it takes shape and much like ice in the way it is formed. That being said, the product, unlike ice, will retain its qualities when subjected to heat or cold. Once the black Flex Seal Liquid has dried and acquired its shape, it can be painted any color that is desired by the user.
