Epoxy waterproofing resin is a strong and durable liquid material used to protect surfaces from water damage. It is made by mixing two components a resin and a hardener which chemically react to form a hard plastic coating. This coating is resistant to water chemicals and abrasion making it ideal for use in bathrooms kitchens basements roofs and industrial areas. Once applied it forms a seamless and long lasting barrier that prevents moisture from penetrating the surface. It can be used on concrete metal wood and other building materials.
