FAQ Section

Q1: What’s the main difference between a water repellent spray and a seam sealer?
A: A water repellent spray is generally applied to the entire surface of a fabric to restore its ability to shed water, often by refreshing the Durable Water Repellent (DWR) coating. A seam sealer, on the other hand, is a more viscous liquid or paste specifically applied along stitched seams to prevent water from penetrating through the tiny needle holes. Both are crucial for keeping your gear waterproof, but they address different points of water entry.

Q2: How often should I reapply a water repellent or seam sealer to my outdoor gear?
A: The frequency depends on how often you use your gear and the conditions it’s exposed to. As a general rule, reapply a water repellent when water no longer beads up and rolls off the fabric, but soaks in instead. Seam sealers should be checked annually or after heavy use; reapply if you notice any peeling, cracking, or leaks along the seams.

Q3: Can I use a seam sealer to repair a small tear in my tent fabric?
A: Yes, many seam sealers, especially those with a thicker consistency or adhesive properties like GEAR AID Seam Grip WP, can be used for minor tears or pinholes. For larger tears, you might want to use a patch kit in conjunction with the seam sealer for a stronger, more durable repair.

Q4: Is it safe to use these products on all types of outdoor fabrics?
A: Most general-purpose seam sealers and water repellents are safe for common outdoor fabrics like nylon and polyester. However, always check the product’s label for specific material compatibility. Products like Atsko Sno-Seal are exclusively for leather, while some sealers are better suited for specific coatings like PU. When in doubt, perform a spot test on an inconspicuous area first.

Q5: How do I properly prepare my gear before applying a water repellent or seam sealer?
A: Proper preparation is key for optimal adhesion and effectiveness. Always clean your gear thoroughly to remove dirt, grease, and old, flaking coatings. Ensure the surface is completely dry before application. For seam sealers, a clean, dry surface ensures the best bond. For water repellents, cleaning helps the DWR bond properly to the fabric fibers.

Q6: Are there any eco-friendly options available for water repellents and seam sealers?
A: Yes, many brands are now offering more environmentally conscious options. Look for products that are PFC-free (per- and polyfluoroalkyl chemicals) or feature water-based formulas. While the products reviewed here are effective, researching brands committed to sustainable practices can help you find greener alternatives for which is the best water repellent and seam sealer for you and the planet.
