A leaky tent will create a very uncomfortable sleeping situation on a camping trip. Making repairs to the tent is possible in the field if you carry a repair tent. Repairs may also be made in the home to ensure they are not rushed and are properly completed. Most tents will spring leaks at the seams and the size of leak will increase as repairs are postponed. Make the repairs immediately to prevent the leak from growing out of control.
Erect the tent outside on a sunny day. Stake the tent to ensure it is safe from any sudden gusts of wind. Do not attach the rain fly to the tent.
Wipe down all of the exterior seams with a wet rag. The seams are easily located by the distinct stitching. Enter the tent and wipe down all of the interior seams. Be sure to clean the floor and window seams.
Open a tube of seam sealer and squeeze a thin amount of the sealant along the exterior of the seams. Start with the large seams and use toothpicks and paper towels to manage any spilling and overflow. Also hit the smaller seams that are accessible from the exterior.
Enter the tent and run a bead of sealer on the floor seams to ensure water runoff does not enter the tent. Use the toothpicks and paper towels to prevent spilling and to manage a clean line. Leave the tent in the sun for two hours to dry the sealant.
Attach the rain fly to the tent once the sealant is dry. Apply a bead of the sealant to the seams on the outside of the fly. Leave the tent in the sun for an additional two hours to dry. Remove the fly and disassemble the tent.
