Things You'll Need
Instructions
Clean the tent with the alcohol and the cloth. Some seam sealers come with a pre-cleaning solution. You can opt to use that to clean the tent, if you wish.
Separate the seam areas of the tent by pulling them away from each other.
Apply a small amount of sealant on the seam of the tent. Rub the sealant in with a brush. Do this to each area you put sealant on.
Add sealant to the foundation of the tent poles. Seal the tent's floor area as well, since water can easily enter this part.
Apply sealant to any other part of the tent that can be damaged by inclement weather. Let the tent dry for 24 hours before using it.
