Double Sided Tape


EternaBond's new pressure activated MicroSealant Technology is a sealant so advanced it permanently bonds to virtually any roof type. Also great for repairing flashings, gutter, skylights, copings, ductwork, and more.

DoubleStick is pure EternaBond advanced MicroSealant with a removable siliconized release liner on each side. Designed to bond two surfaces, even two surfaces made of two or more dissimilar materials. Double- Stick creates a tight, permanent, waterproof seal. DoubleStick remains flexible to temperatures as low as -57°C making it virtually impossible to thermally shock the seal causing a leak.

DoubleStick Bonds to a wide range of surfaces including EPDM, TPO, most PVC, CSPE/ Hypalon, CPE , SBS, APP modifieds, asphalt BURs, coal tar BURs, tiles, shingle, coated and non-coated aluminum and metal roofs, galvanized steel, gypsum board, wood, polyethylene, propylene, polystyrene, fiberglass, brick, concrete, masonry, OSB board, shielding membranes, etc.

Basic Use
DoubleStick tape is a self-sealing adhesive creating a water-tight, conformable seal between two or more irregular surfaces, and/or creates a weather proof, permanent bond between two or more similar or dissimilar surfaces. Use as a lap seal, under the foot of an equipment curb or skylight, or roll it into a bead or ball of MicroSealant to form a gasket, seal a hole or gap as needed.

DoubleStick 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, between two silicone release liners.

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.


To apply the DoubleStick, remove one side of the release liner and apply to the surface to be protected or bonded. Rub or roll with pressure using your hand or a steel roller to activate bonding process. Remove the second release liner and apply second surface to tape, apply pressure. DoubleStick also can be used as a putty.
Remove both release liners and roll into a rope. Place over gap and mold to seal opening. This material may be applied to clean dry surfaces from 66°C to -29°C ambient. Treat surface with EternaPrime for installations from 5°C to -29°C ambient.
