10 Best Glues For Inflatable Boats 2025 in the United States

The HH-66 Vinyl Cement by RH Adhesives is a strong contender for gluing inflatable boats. It's specifically designed to work with vinyl and plastic materials, making it a good match for most inflatable boat surfaces. One of its standout features is its excellent water resistance, even performing reliably underwater. This ensures that repairs made with this adhesive will hold up well in marine environments. The adhesive can be applied in a wide range of temperatures, from 35 to 95 degrees Fahrenheit, adding to its versatility in different weather conditions.

Another plus is its flexibility, which means it won't crack or become brittle over time, maintaining the integrity of the inflatable boat as it flexes and moves in use. The application method is user-friendly thanks to the included brush, ensuring the adhesive goes on smoothly whether using it on the fabric or hard plastic parts of the boat. As a solvent-based adhesive, it could emit strong fumes, so good ventilation is necessary during application.

Made in the USA, this product has a reputation for quality and reliability, backed by RH Adhesives' long-standing history since 1949. The HH-66 Vinyl Cement is a solid choice for repairing and maintaining inflatable boats, with its water resistance, flexibility, and material compatibility being its primary strengths.

The PVC Stitch Liquid Repair Patch is a versatile and durable glue designed for a range of inflatable materials, including PVC and PU. It's notable for its strong material compatibility, making it suitable for repairing air mattresses, waterbeds, above-ground pools, inflatable boats, and more. The adhesive is water-resistant, which is crucial for outdoor and water-related repairs.

It also boasts UV and temperature resistance, ensuring durability in various environmental conditions. The curing time is relatively fast, with a usable time of 2 hours and maximum strength reached in 6 hours, suitable for quick repairs. The application method is straightforward: apply the liquid PVC evenly over the damaged area, and it cures into a permanent patch without the need for additional patches.

This simplicity makes it user-friendly, even for those with little repair experience. However, it does not work on nylon-based materials, which is a limitation if you need to repair nylon items. The product comes in a small 20 milliliter tube, which may not be sufficient for larger repairs. PVC Stitch is a reliable choice for quick and durable repairs on a variety of inflatable PVC and PU items, though its limited material compatibility and small tube size should be considered.

The GEAR AID Aquaseal FD Flexible Repair Adhesive is specifically designed for repairing outdoor gear and vinyl, making it an excellent option for fixing inflatable boats. One of its primary strengths is its broad material compatibility; it works well with vinyl, neoprene, nylon, canvas, leather, rubber, and even GORE-TEX fabric. This makes it versatile enough for various repair needs beyond just inflatable boats.

Its waterproof nature and ability to create a flexible, durable urethane rubber seal that doesn’t peel or crack over time ensure that repairs are long-lasting and reliable even in wet conditions. Users will appreciate its resistance to abrasions and extreme temperatures, which adds to its durability under harsh conditions. The curing time of 8-12 hours is relatively standard and reasonable, though users needing quick fixes might find this a slight inconvenience.

The adhesive comes in a 0.75 oz tube, which may be sufficient for smaller repairs, but larger jobs might require more product or a larger size option. The paste form might be slightly challenging to apply precisely, but it does ensure a strong, stable bond once cured. The product's high viscosity can sometimes make application a bit tricky for beginners. This adhesive is well-suited for those needing a reliable, flexible, and waterproof solution for repairing inflatable boats and a variety of other outdoor gear.
