Fast Fixes…At Home
Problem Mold; musty smell
Solution Mildew and fungus aren’t just unsightly: They destroy waterproof coatings. Dry your tent before packing up, then again at home. Too late? Remove mildew by scrubbing with a soft brush and non-detergent soap, then with a mixture of 1 cup salt, 1 cup concentrated lemon juice, and 1 gallon hot water. Dry in the sun, peel off any damaged coating, then apply a sealant (such as McNett Tent Sure, $7) to damaged areas.
Problem UV degradation
Solution Sun can cause fabrics to stiffen and coatings to peel–especially at altitude. Prevent damage with Granger’s Spray-On UV Waterproofing ($14, altrec.com).
Problem Leaky seams
Solution Apply Seam Grip ($6) to all seams inside the tent–including guyline attachment points. "The most common point of entry for water is where webbing attaches to the canopy, like at clips, guy-outs, and stake-out points," says George Farkas, product manager for McNett. "Webbing wicks water through the fabric, and before you know it, the dripping starts." Farkas suggests applying a thin bead of Seam Grip across each piece of webbing, right where it exits the tent fabric. The sealer will act like a dam to prevent water from seeping in.
Fast Fixes…In the Field
Problem Rips in tent body
Solution These can spread quickly, so repair ASAP. Andrew Day, Kelty’s tent product manager, recommends covering rips with tape from Coghlan’s Nylon Tent Repair Kit ($5, coghlans.com). Clean and dry the area, and trim loose threads. Cut a patch with rounded edges (to prevent peeling) that extends 1/4-inch beyond the tear on all sides. Pull torn edges together, apply patch on the inside (where it’s protected), and smooth from the middle out.
Solution Create a venting system. Open the bottom of a door at one end and the upper part at the opposite end. Tighten guylines to keep the fly from touching the walls.
Problem Broken pole
Solution Fit a small metal sleeve (found in most repair kits) over the break. Reinforce with duct tape.
