Most of our current tents are completely seam taped or welded and require no additional seam sealing; however, if you crave additional peace of mind and want to back up the factory taping with additional seam sealing, you can apply aftermarket seam sealer to key seams and stress points.
If you are so inclined, our recommendation would be to seal the bias-bound floor perimeter seam on applicable styles (where the sidewall meets the floor) as well as the underside of the fly where guy out webbing, Velcro, or other attachments are sewn in along the seams. Do not seal the tent canopy or zippers.
For the few tents that are not completely factory seam taped (this will be noted in the pitching instructions) all seams not taped and that will be exposed to the outside elements will need to be seam sealed. In these limited styles, we actually provide the seam sealer with the tent.
Instructions for seam sealing your tent:
Pitch the tent in a well-ventilated area (preferably outside, and in the shade). Make sure the tent is clean, dry, and taut. Stake out the tent floor. Never seam seal in cold, damp, or humid environments. Seal the inner, coated (shiny) side of the fabric only. Seam sealer does not adhere as well to the uncoated side because the water repellant finish is applied to that side. Apply several thin coats instead of one thick coat, and work the seam sealer thoroughly into the seams by applying pressure and brushing the liquid back and forth. Follow the drying instructions on the seam sealant tube carefully to prevent damaging your tent.
Our recommendation for an effective and durable sealer is the McNett product "Gear Aid™ Seam Grip".
