Will Scotchgard waterproof a tent?
Scotchgard can waterproof the fly and walls of a tent, but it will not seal the seams and floor of your shelter.

How long does it take to waterproof a tent?
From setting up the tent to the moment you can take it off and pack it back in its bag, waterproofing an entire tent – comprising floor and tarp – takes 24 hours. If you’re only resealing the seams or fly, account for about 6 hours.

How often do tents need waterproofing?
It depends on how often you use the tent. Casual campers using the tent for 2-3 weeks per year on average should waterproof their tent every 2 years. If you use your tent more often, consider sealing it every 6-12 months, or whenever it leaks.

Do you seam seal inside or outside of tent?
You should seal the seams with seam sealant on the inside of the tent or the inner side of the fly, applying approximately ¼-inch past the seams on either side.
