DRY: ALLOW TO FULLY DRY before use of folding (minimum 4 hours at room temperature; longer if colder). Test for dryness before use of storage.

Perimeter seams on "seam taped" tents are often not factory sealed and require sealing. Apply a thin film of Seam Sure to inside floor seams. Allow to dry overnight.
Use Seam Sure to seal areas that regularly leak, such as stake-out points at corners.
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.
