The "close enough" approach to tent repair won't get you very far. Tents are subject to heavy stresses from rough ground, high winds and just normal use. Take a deliberate approach and you won't be sorry. A standard sewing machine should easily handle the work, but if you don't have experience with sewing machines, consider finding someone who does. Seam-sealing glue and heavy-duty nylon cloth are available at camping supply stores.
Clean the torn area with dishwashing liquid and water, then thoroughly dry the tent.
2
Cut two patches of heavy-duty nylon cloth about 2 inches (5 cm) larger than the tear (see A).
3
Coat one side of each patch with seam-sealing glue. Let them dry until the glue becomes tacky.
4
Apply one patch to each side of the torn area. Be careful to keep the tent material under the patch as flat as possible. This will ensure watertightness.
5
Using a sewing machine, zigzag-stitch completely around the edge of the patches. Continue stitching over the patches in a dense zigzag pattern (see B).
6
Apply additional seam-sealing glue to the stitching, both inside and out.
Tips & Warnings
Tents intended for mountaineering or extreme weather should be considered survival equipment. Have the manufacturer or a professional assess whether the tent can be repaired.
