For use on virtually all roofs, WebSeal designed to hold coatings, whether water or solvent based. WebSeal makes the roof water-tight prior to application of coating, creating a superior, faster method of waterproofing over conventional 3 course applications, eliminating dependence on the roof coating as a water barrier.
WebSeal remains flexible to temperatures as low as -70°F making it virtually impossible thermally shock the seam causing a leak. WebSeal bonds to a wide range of surfaces including difficult roof materials such as EPDM, TPO, CSPE/Hypalon, most PVC, CPE , SBS, APP modified, asphalt BURs, coal tar BURs, plus all metal roofs, tiles, shingle, aluminum, Galvanized steel, gypsum board, wood, polyethylene, propylene, polystyrene, fiberglass, brick, concrete, masonry, OSB, etc.
WebSeal tape is used to seal roof joints (seams) and tears, flashings, copings, skylights, gutters, etc. Perfect for repairing and restoring roofs on mobile homes and RVs. Extremely flexible, with no memory, so WebSeal conforms to virtually any shape without springing back. WebSeal seals to itself so it can be cut and folded around an object. A top coat of roof coating is necessary for UV protection.
WebSeal utilizes EternaBond’s advanced MicroSealant Technology, a 100% solids formulation of synthetic resins, thermoplastics and noncuring rubber (non butyl) with a built in primer. It is bonded to a woven polyester backing for maximum conformability. The adhesive coating is protected by a silicone release liner, to be removed prior to application.

Surface must be clean and dry. Moisture, dust, dirt, or other foreign matter should be removed. Remove oil and grease, etc. with EternaClean or a non residue cleaner such as acetone or lacquer thinner. Remove salt and other contaminants
Install WebSeal over the repair area, removing the release liner gradually to prevent contamination of the adhesive prior to application. Rub or roll with pressure using your hand or a steel roller to activate bonding process. This material may be applied to clean dry surfaces from 150°F to -20°F ambient. Treat surface with EternaPrime for installations from 40°F to -20°F ambient.
