    Detailed Repair Instructions

    Before you begin

    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 isopropyl alcohol before repairing. For Best Results: For professional looking repairs use Seam Grip alone or Seam Grip with Cotol-240 plus Cure Accelerator (to speed cure time to 2-4 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 6 mm beyond (Fig 1). Allow to 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 1 CM BEYOND SEAM GRIP AND BOND DIRECTLY AND SOLIDLY TO PAD FABRIC. This minimizes the possibility of Seam Grip seeping out from under patch.

    Pad may be used immediately. Remove patch after 3 days, Seam Grip repair is permanent.

    To Seal Leaking Tent Seams

    Seal seam inside tent. Apply Seam Grip to seam. Brush under fabric folds and into stitching. (Fig. 4) Allow Seam Grip to cure 8 to 12 hours before packing tent.

    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)

    The McNett Instant Repair Kit is super helpful and only weighs half an ounce! There is no reason not to have one, even if you use it for repairs when you get home. 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.“

    Paddlesports Tip

    Kayak cockpits are notorious for cutting into spray skirts and causing exterior cracking. Apply spot applications of Aquaseal to permanently repair and protect both the interior and exterior.



    Rebonding Soles

    Use Freesole® to permanently re-bond a peeling boot sole. First remove loose dirt and debris and then clean the area with rubbing alcohol and a stiff brush. Apply Freesole to the sole evenly.
