Seam-sealing your own tent is easier than it sounds! We’ve got a video that guides you through the process and a kit that takes care of the hard part for you (mixing the goop).
The seam sealant takes 3-4 hours to dry depending on outside conditions. If it isn’t dry by the time you need to bring it in, you can take it down and throw it over a chair for the night.
After the sealant is dry, you can “check your work” by spraying the sealed shelter with a hose and watching the seams to see if water leaks in.
