Seamax Repair Kit for Inflatable Boats
The Seamax Repair Kit uses a professional two-part glue system designed for PVC surfaces on inflatable boats. It comes with clear guidance on mixing ratios and a methodical application process to maximize adhesion. For best results, mix a small amount of hardener into the base glue, apply in multiple layers, and clamp the patched area to ensure air-free bonding. The kit emphasizes proper surface prep, including using a solvent like MEK to clean and lightly roughen the patch site, which helps the glue form a strong bond. A curing period of 48 hours is recommended before use.
Key features:
- Two-part glue with clear mixing instructions
- Recommended dry touch and cure times for durable repairs
- Guidance on surface prep, layering, and pressurized bonding
Seamax Commercial Grade 2 Part Marine Adhesive
This commercial-grade adhesive is designed for all PVC inflatable boats and Hypalon surfaces, packaged in aluminum bottles for long-term storage. It uses a 2-part system with a hardener that must be mixed into the base glue in controlled amounts to avoid brittleness or under-curing. The instructions emphasize applying multiple thin layers, moving from the center outward to remove air bubbles, and maintaining pressure for a full 24 hours. For the strongest bond, the kit recommends a 48-hour cure before inflating or testing the repaired area.
Key features:
- 2-part system with hardener and base glue
- Clear mixing ratios and cure guidance
- Storage and reactivation tips for aged glue

Buying Guide: Key Considerations For Choosing PVC Glue For Inflatable Gear
When selecting the right glue or patch kit for inflatable boats and PVC equipment, a few considerations help balance performance and practicality:
- Repair type: Choose between patch kits with adhesive-backed patches, liquid patches, or two-part glues for structural repairs. Small punctures may be covered with patches, while larger tears benefit from two-part formulations.
- Material compatibility: Confirm the product works with PVC, EVA, and Hypalon surfaces if you own a range of gear. Some adhesives are more versatile than others.
- Bond strength and cure time: Professional-grade two-part systems typically offer stronger bonds but require precise mixing and longer cure times. Liquid patches and single-component glues may cure faster but offer differing durability.
- Surface prep guidance: Products that specify solvent cleaning (e.g., MEK) and surface roughening provide stronger, more reliable bonds. Follow prep steps carefully to maximize adhesion.
- Environmental tolerance: UV resistance, saltwater compatibility, and temperature tolerance influence longevity. For gear used in harsh environments, prioritize water resistance and UV stability.
- Storage and shelf life: Two-part systems stored properly in labeled containers usually last longer than single-component liquids that may dry out or lose potency.
- Cure window: If you need rapid use after repair, consider products that become usable within hours and allow full cure over 24–48 hours for strength.
In summary, Seamax offers professional-grade two-part options and comprehensive guidance for robust repairs. AquaPro and Yeardera provide versatile, user-friendly patches with broad material compatibility. SEA DOG supplies a practical, general-purpose adhesive for quick fixes, while BRIS’s multi-tube set offers a budget-friendly option for frequent repairs. Evaluate your gear type, expected exposure, and desired cure time to pick the best match for your inflatable fleet.
