EternaBond® WebSeal®

1 of 17 products in this brand
EternaBond® WebSeal® is a reinforced fabric, coated with EternaBond®’s advanced MicroSealant®. WebSeal® is a faster way to seal roofs and can be painted to match existing surfaces. WebSeal® is designed to work with both water and solvent based coatings. WebSeal®’s “no memory” construction allows it to conform to many irregu-lar surfaces like screw heads, standing seams, gutters and more. WebSeal® remains flexible to temperatures as low as -57°C (-70°F) making it virtually impossible to thermally shock the seal causing a leak. WebSeal® bonds to a wide range of surfaces including EPDM, TPO, Hypalon, aluminum, galvanized steel, gypsum board, wood, many plastics, fiberglass, brick, concrete, and masonry. Ensure all surfaces are clean, dry, and free of debris prior to in-stallation.

Composition

EternaBond® WebSeal® utilizes EternaBond's advanced MicroSealant Technology, a 100% solids formulation of synthetic resins, thermoplastics and non-curing 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.

Basic Use

EternaBond® WebSeal® is used to seal roof joints (seams) and tears, flashings, copings, sky- lights, 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.

Surface Preparation

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.

Product Limitations

EternaBond® WebSeal® is not compatible with silicone sealants or lubricants. Avoid using silicone based products near WebSeal®.

Application Information

Surfaces must be clean and dry before applying WebSeal®. 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 steel roller to activate bonding pro- cess. A topcoat is required for UV protection.
