Eternabond WebSeal Roof Seam Tape has advanced MicroSealant Technology to seal roof joints (seams) and tears, flashings, copings, skylights and gutters permanently prior to the application of roof coatings.


Built Up Roofing (BUR), Concrete Roofs, Metal Roofs, Modified Bitumen, Polyurethane Foam, Single Ply Roofing (PVC, TPO).

Roof repairs. Any roof seam, flashing, penetrations or joints that require sealing prior to coating application.


  • 100% solids formulation of synthetic resins, thermoplastics and non-curing rubber (non butyl) with a built in primer, bonded to a woven polyester backing for maximum conformability.
  • Designed not to harden under even the most rigorous conditions.
  • 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.


See table on the following page.


  • All surfaces to be coated must be clean, dry and free of any oil, grease or dirt.
  • Oil, grease, other contaminants should be removed with a suitable solvent/cleaner. Use of EternaPrime reduces clean up.
  • For older plastic roofs, score surface with sand cloth and wipe away dust.
  • Install Eternabond® WebSeal over the repair area, removing the siliconized plastic release liner gradually to prevent contamination of the adhesive prior to application.
  • Rub or roll with pressure with hand or steel roller to activate bonding process.
  • This material may be applied to clean dry surfaces from -20°F to 150°F.
  • Treat surface with EternaPrime for installations from 40°F to -20°F. A topcoat of roof coating is necessary for UV protection.

      I ordered a gallon of Liquid Rubber last summer, and inquired if it could be spread with an adhesive applicator trowel; the sales person was not aware of this having been tried. I tried using a commercially available trowel with 4 sawtooth teeth per inch, and 0.135 inch notch depths, holding the trowel at about a 45 degree tilt.

      Everyone was SUPER helpful and knew the product, properties and application methods well. I applied to product on the trailer in about a 2-hour period one evening. It was tricky with the application, from a novice who had not done this before.

      Donna,your staff and your customer service is the reason we buy from you. You had asked us several months ago if we would write up something for your Website. We wanted to get some additional orders first before coming to conclusions.

      We have completed the resurfacing of our commercial roof back in April and ordered a few more pails for areas where we probably did not apply it thick enough. Just wanted to share these photos with you.

      You have a great product here and we will be ordering for future jobs we have. We were a bit skeptical at first but when it was fully dry it looked as if we installed a new 15,000 sq piece of sheet EPDM.

      This will be the third time our firm has ordered. We completed a project in 05 in the fall and waited for the winter. This was actually the first winter without any leaks. Great product overall.
