    Important Surface Prep Information: Clean and dry area to be repaired. Oils, waxes on boots, sunblock and other residue may affect adhesion. Remove oils and waxes on boots with McNett Seam Cleaner or isopropyl alcohol before repairing. For Best Results: For professional looking repairs use Seam Grip alone or Seam Grip with Cotol-240 Cure Accelerator (to speed cure time to 2 hours). Repairs using a few drops of water to speed cure time are less aesthetic.

     

    To Repair Holes in Self-Inflating Mattresses: Apply Seam Grip to cover hole and spread ¼ inch (4mm) beyond (Fig 1). Allow to dry level 8 hours.

     

    TO USE PAD SOONER: Technique for small (dime-sized) repairs only. Mix a few drops of water into Seam Grip® before applying to hole. Apply mixture and allow to cure level for 30 minutes (Fig 2). Then center patch and apply over Seam Grip .

     

    PATCH MUST EXTEND AT LEAST ½ INCH BEYOND SEAM GRIP AND BOND DIRECTLY AND SOLIDLY TO PAD FABRIC (Fig. 3). This minimizes the possibility of Seam Grip seeping out from under patch.

  • Testimonials

  • What is it? –

      When cured (dry) Seam Grip is a very thin, clear, elastic urethane rubber.

  • How it works —

      Seam Grip is applied to a stitched seam, a hole or a tear and allowed to cure over a period of 8-12 hours.

    • When applied, Seam Grip cures by reacting with humidity in the air. It doesn’t ‘dry’ the way other glues do. It changes from a moderately thick liquid to a thin, flexible, elastic rubber.

    • Once cured, it’s permanent. The repair will generally last the life of the item.

  • Additional User Comments —

      Users are always impressed at the extreme toughness and waterproofness of seams sealed with Seam Grip

      We have had users make tents and tarps without stitching by simply bonding all the seams with Seam Grip. The results have been incredibly strong, waterproof shelters

      Many users have commented that “factory seam tapes last a certain number of years, but Seam Grip lasts forever.”

      Users have sealed seams on tents, packs, outerwear, boots and much more.

      Seam Grip is also heavily used to patch holes in tents, packs, clothing and other gear using the ‘plastic tape backing method’ (see diagram under the instruction tab)

It has everything you need to fix all minor repairs on tents, packs, boots, sleeping pads, raingear, and anything else you can think of. I have pulled mine out numerous times when I have snagged things bushwhacking or have gone sliding downhill on talus and have had to do some surgery on my gear."

  • Boot Use Tip

    Boot Use Tip

    TRUE OR FALSE? Heavy duty mountain boots are obsolete for backpacking. True. But while the ultralight backpacking crowd (carrying 20 lb. packs) get by on trails using trail running shoes or even good sport sandals, most folks carrying heavier loads should have some ankle support. Well-made light hikers with a 3/4 or full-height ankle collar are usually enough for moderate loads on most trails.
