GEAR AID Seam Grip WP Waterproof Sealant
The Seam Grip WP provides a permanent seal for seams and holes in nylon, canvas, vinyl, and similar fabrics. It cures into a flexible rubber seal that moves with fabric, making it suitable for inflatable boat seams and various outdoor gear. It covers up to 12 feet of seams per 1 oz tube and bonds to multiple materials including nylon, polyester, canvas, leather, and vinyl.
Best for: Quick, durable repairs on fabric seams and patches. This is ideal for inflatable boats, tents, tarps, and gear that flexes with movement.
Why selected: It combines strong adhesion with flexibility, reducing the risk of new leaks at seam joints. The 1 oz tube format is convenient for travelers who need targeted repairs.
Caution: Larger repairs may require multiple tubes, and curing can depend on humidity and temperature. Ensure clean, dry seams before application.
GEAR AID Seam Grip FC Fast Cure Sealant
Seam Grip FC is a water-based sealant designed to seal up to 60 feet of seams on tents, tarps, and awnings made of nylon, vinyl, or canvas. It cures in about 2 hours at room temperature and dries nearly invisible while maintaining flexibility with fabric.
Best for: Quick, larger seam repairs on outdoor fabrics where speed matters. Suitable for inflatable boat interiors and covers that require a discreet seal.
Why selected: The FC formula provides a fast cure and extended seam coverage, helpful for larger inflatable gear or tents used around boats.
Caution: It’s water-based; ensure the surface is clean and dry for best adhesion. Purely painted or highly textured fabrics may affect invisibility of the seal.

Why selected: It offers a quick, durable fix for PVC surfaces common in inflatable boats and accessory items.
Caution: This product is best for PVC; performance may vary on non-PVC fabrics. Follow curing times for optimal adhesion.
EPN Air Mattress Patch Kit
The EPN kit includes heavy-duty vinyl repair patches and a strong vinyl adhesive. It offers waterproof, airtight patches suitable for inflatable products, PVC trampolines, tents, and pool equipment. Patches come in multiple shapes to fit different damage patterns.
Best for: Repairs on larger punctures or holes in inflatables and PVC surfaces beyond small sealer spots.
Why selected: Its versatility and durable patches help extend the life of inflatables used on boats or at the shore.
Caution: Cure time and color matching may vary with patch size and surface texture. Ensure surfaces are clean for best adhesion.
Yeardera Patch Kit for Inflatables
The Yeardera patch kit provides a high-strength vinyl adhesive designed to bond patches to PVC inflatable surfaces. It claims waterproof, air-tight results and UV resistance to help prevent yellowing. Includes patches and adhesive in a 60 ml pack.
Best for: Permanent repairs on PVC inflatables, boats, and pool gear that require a strong, lasting bond.
Why selected: Strong adhesion and UV resistance help protect repairs in sun-exposed boat environments.
Caution: Cure times can vary; fully cure before putting repaired gear back into use in water conditions.
Buying Guide: Key Purchase Considerations
- Material compatibility: Choose products that specify nylon, canvas, vinyl, PVC, or TPU compatibility. Inflatable boats commonly use PVC and vinyl fabrics; ensure the sealer or patch is designed for these materials.
- Repair type: For seams, choose seam sealants (WP or FC). For holes or punctures, patches or adhesive sealants (PVC-specific) are often better.
- Drying and curing time: If you need a fast fix before a trip, prefer products with quick cures. Consider ambient conditions as humidity and temperature affect curing.
- Flexibility after cure: Flexible seals move with fabric to reduce re-leaks at seams or repairs on moving parts of the boat.
- Waterproof and UV resistance: For outdoor boat use, waterproofing and UV protection help extend the life of repairs.
- Portability and ease of use: Compact tubes and kits are beneficial for field repairs and travel.
- Patch size and coverage: Consider the anticipated repair area. Some products cover only small seams; larger repairs may require more material or patches.
Frequently Asked Questions
- Can I use these products on an inflatable boat made of PVC? Yes. Many sealants and patch kits are designed for PVC and vinyl materials used on inflatables.
- Do seam sealants dry clear? Some, like Seam Grip FC, cure nearly invisible, while others may show a slight colored seal. Check product descriptions for finish details.
- Is a patch kit better than a liquid sealer for large holes? For large holes, patches plus compatible adhesive typically provide a stronger, longer-lasting repair; sealants are great for seams and smaller leaks.
- How long should I wait before exposing a repaired boat to water? Cure times vary by product; follow container guidance and ensure surface is fully dry and cured before use.
- Are these products safe for skin contact? Most sealants are water-based or solvent-based; follow label instructions and avoid prolonged skin contact.
- Will repairs last in saltwater environments? Proper surface prep and selecting UV-stable, waterproof formulations improve longevity in saltwater conditions.
