Seam Sealing
- Temperature should be above 60° F (16° C) and humidity below 80%.
- Pitch tent/tarp tightly so all seams are taut.
- Apply outside or in a well-ventilated area. Wear gloves.
- Clean seams on a used tent/tarp with isopropyl alcohol.
- Squeeze a little glob of seam sealer in a small container, like a plastic cup. You can thin seam sealer by repeatedly pouring in small amounts of mineral spirits and mix with a stir stick until reaching the consistency of olive oil. Start small and mix more sealer as needed.
- Using a brush or foam applicator, carefully apply a thin coat across the seams, making sure the seam sealer gets in all the stitching holes. For rolled seams, also apply where the edge of the seam rolls under. You only need to seal the outside of the shelter. Take your time to be neat. After a few minutes the applied seam sealer will begin to gel, so don’t go back over the seam with a brush or it will get gummy and look bad. Missed spots can be touched up after waiting at least 8 hours.
- Clean hands with soap and water.
- Allow 24 hours to dry while the tent/tarp is still pitched taut. Test for tack before folding or using. A light surface tackiness is normal on freshly-cured Seam Grip and will dissipate with use. Tack can be eliminated by dusting with unscented talcum powder.
Pinhole Repair
- Temperature should be above 60° F (16° C) and humidity below 80%.
- Apply outside or in a well-ventilated area. Wear gloves.
- Clean around hole with isopropyl alcohol.
- Place clear tape on back side of fabric across hole.
- Squeeze a little glob of seam sealer on a piece of paper.
- Using a brush, carefully apply a thin coat across the pinhole and 0.25 in. (6 mm) around. Take your time to be neat.
- Clean hands with soap and water.
- Allow 24 hours to dry. Test for tack before folding or using. A light surface tackiness is normal on freshly-cured Seam Grip and will dissipate with use. Tack can be eliminated by dusting with unscented talcum powder.
- Remove clear tape.
