10 Best Glues For Inflatable Boats 2026 in the United States

The HH-66 Vinyl Cement by RH Adhesives is a strong choice for bonding inflatable boats and similar vinyl or PVC materials. It adheres well to a wide range of surfaces including flexible vinyl, PVC, neoprene, and some plastics, making it versatile beyond just boats. One of its standout features is its excellent water resistance; it’s designed to be waterproof and even works underwater during application, which is a significant advantage for marine repairs.

The glue remains flexible once cured, helping to prevent cracks or brittle seams even with temperature fluctuations from -30°F to 150°F. This flexibility is vital for inflatables that must endure bending and pressure. Application is straightforward due to the built-in brush, allowing for even spreading and a smooth, professional finish. The curing time is about 24 hours, requiring some patience before full use. The product is solvent-based with medium viscosity—thick enough to hold well but still easy to work with. It performs best when applied within a temperature range of 35°F to 95°F, as extreme temperatures can affect bonding effectiveness. Though it dries quickly, it does not come with a warranty, which could be a consideration for some users.

HH-66 is a durable, waterproof, and flexible adhesive designed for tough, long-lasting repairs on inflatable boats and other vinyl-based items. It meets the needs of users seeking a professional-grade glue that withstands water exposure and temperature changes, provided that application occurs within the recommended temperature range for optimal results.

The HH-66 Vinyl Cement by RH Adhesives is a strong contender for gluing inflatable boats.

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.

The product is manufactured in the USA by RH Adhesives, a company with a long history since 1949, which adds to its reliability.

The glue likely offers good flexibility after curing, important for inflatables that bend and move, though extremely hot or cold conditions might affect the bond quality. The application method is straightforward as a liquid cement, suitable for patching seams, decals, and small fixes without complicated preparation. This glue is a dependable, safer choice for most inflatable boat repairs, especially if you want a waterproof, flexible bond, but it’s not suitable for polyethylene tarps or ultra-thin vinyl surfaces.
