How to Waterproof Your Tent with Nikwax Spray

Quick answer

Use Nikwax Tent & Gear SolarProof Spray to add waterproofing and UV protection to your tent's fabric. Apply after cleaning, on a dry day, and allow full cure before packing.

Step-by-step tent waterproofing with Nikwax Spray

1. 1. Set up and clean the tent: Pitch the tent in a well-ventilated outdoor area, away from direct sunlight if possible. Brush off dirt and debris. If the fabric is visibly dirty, wash it with a dedicated tent cleaner (like Nikwax Tent & Gear Cleaner) and let it dry completely. A common mistake is applying waterproofing over dirt or moisture, which prevents the spray from bonding. Clean fabric ensures the spray adheres evenly and lasts longer.
2. 2. Shake and test the spray: Shake the Nikwax SolarProof can vigorously for about 30 seconds. Spray a small test patch on an inconspicuous area (like a corner of the fly) to check for color change or residue. If the fabric darkens temporarily, that's normal—it will dry back to its original shade. Always test on a hidden spot first, especially on colored or coated fabrics.
3. 3. Apply the spray evenly: Hold the can 6–8 inches from the fabric and spray in a steady back-and-forth motion, covering one section at a time. Work from the top of the fly downward to avoid drips. Apply a light, even coat rather than soaking the fabric. Pay extra attention to seams and high-wear areas. A common mistake is overspraying, which can cause pooling and uneven drying. Thin, even coats work better than one heavy application.
4. 4. Let it dry completely: Allow the tent to air dry for at least 2–4 hours, or as directed on the can. Do not pack or fold the tent while it's still damp—the treatment needs to cure fully. If the weather is humid or cool, extend the drying time. A common mistake is rushing this step, which leads to poor water repellency and a tacky feel. Full cure time is essential for the waterproofing to bond to the fabric.
5. 5. Test and store properly: 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 and repeat the drying step. Store the tent loosely in a breathable sack, not compressed, to preserve the coating. A simple water test confirms whether one coat is enough or a second is needed.
