Instructions for Use

Seam Sealing

PREP: Clean seams on used tents with Cotol-240™ Cleaner & Cure Accelerator or isopropyl (rubbing) alcohol.

APPLY: Apply a thin film of Seam Grip to inside of the seam (one coat).

DRY: Let dry overnight (approximately 8-12 hours—may be longer in low humidity). For 2-hour dry time, mix small batches of Seam Grip with Cotol-240™. Apply with brush.

CLEAN UP: Seam Grip will dry (cure) and flake off hands. Washing hands in soap and water will accelerate curing. Uncured Seam Grip can be partially removed with a coarse cloth soaked in rubbing alcohol. For easiest clean up wear disposable rubber gloves.

STORAGE: Advance contents to tube neck and replace original cap securely. Store partially used tube in freezer.

Special Applications & Tips

Adhesive Applications
Roughen and clean surfaces with rubbing alcohol. Apply Seam Grip to both surfaces. Allow to dry (cure) 15 minutes, then join (clamp or tape) surfaces together overnight.

Tent Seam Sealing
Perimeter seams on ‘seam taped’ tents are often not factory sealed and require sealing. Apply a thin film of Seam Grip to inside floor seams (fig.1). Allow to dry (cure) overnight. A slight surface tack is normal and will dissipate with tent use. Use Seam Grip to seal areas that regularly leak, such as stake-out points at corners (fig. 2). To seal the seams on your rainfly, set it up inside-out for easier application. Attach the rainfly to the tent so all seams are taut (fig. 3).

Tear & Hole Repairs
Apply just enough Seam Grip to cover the hole and spread 1⁄4 inch beyond. Allow to dry (cure) level overnight. For 2 hour cure time, mix Seam Grip with Cotol-240™ before applying. (fig. 4)

Seam Tape Tip
If a small section has peeled use Seam Grip to re-attach it (fig. 5). If the tape seems to be failing everywhere, remove and discard it, then clean the seams with Cotol-240™ or isopropyl alcohol and re-seal with Seam Grip.
