Learn to apply Nikwax Tent & Gear SolarProof and TX Direct Spray-On to restore waterproofing and UV protection to your tent and outdoor gear. Step-by-step guide with common mistakes to avoid.
Quick Answer
Use Nikwax Tent & Gear SolarProof for tents and awnings that need both waterproofing and UV protection, and Nikwax TX Direct Spray-On for synthetic outerwear and equipment. Both are spray-on formulas that work on clean, damp fabric.
Why Choose a Spray-On Waterproofing
Spray-on waterproofing is the easiest way to refresh your gear without soaking it in a wash-in treatment. It lets you target specific areas—like tent seams or jacket shoulders—that wear out first. The trade-off is that spray-ons may not penetrate as deeply as wash-in formulas, so reapplication may be needed more often on heavily used items.
Nikwax SolarProof vs. TX Direct: Which to Use
Nikwax Tent & Gear SolarProof is formulated for weatherproof fabrics like tents, awnings, and covers. It adds both waterproofing and UV protection, which is critical for gear that sits in direct sunlight. Nikwax TX Direct Spray-On is designed for synthetic outerwear and equipment—think rain jackets, backpacks, and gaiters. It restores water repellency without adding UV protection. Choose based on the item you are treating: tents and sun-exposed gear get SolarProof; clothing and packs get TX Direct.
How to Apply Nikwax Spray-On Waterproofing
- Clean and dampen the fabric: Wash the item with Nikwax Tech Wash or a mild soap, then rinse thoroughly. Leave it damp—not dripping—before spraying. Nikwax formulas bond best to damp fabric. Common mistake: applying to dry fabric. The treatment won't spread evenly and may leave blotchy spots.
- Shake the bottle and spray evenly: Shake the Nikwax bottle well. Hold it 6–8 inches from the fabric and spray in a steady, overlapping motion. Cover the entire surface, paying extra attention to seams and high-wear areas. Checkpoint: if you see puddles or drips, you are spraying too close or too heavily. Light, even coats work best.
- Spread with a clean cloth (optional): For large flat surfaces like a tent fly, use a clean damp cloth or sponge to gently spread the spray into the fabric. This helps avoid streaks and ensures even coverage.
- Let it cure: Allow the item to air-dry completely—usually 2–4 hours indoors or up to 24 hours in good ventilation. Do not use heat or direct sunlight to speed drying, as that can damage the coating. Common mistake: packing or folding the gear before it is fully dry. The treatment can peel or stick to itself.
- Test the waterproofing: Once dry, sprinkle a few drops of water on the treated surface. If they bead up and roll off, the treatment is working. If they soak in, apply a second light coat.
