How to Make Your Own Tent Seam Sealer

Although most modern tents are weather resistant, it is generally a prudent idea to apply extra seam sealer to your tent seams before heading out on a camping trip. Applied to the glossy side of the seam, the sealer creates an additional barrier that blocks rain and moisture from entering your home away from home. Save money by making your own seam sealer at home with a few simple supplies from a hardware store.
