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. 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 AquaPro Liquid Patch Waterproof Repair Kit is designed especially for repairing PVC and PU inflatable boats, rafts, paddle boards, and similar outdoor water gear. It works well with materials like PVC and polyurethane but does not suit nylon-based fabrics, so it's important to check your item's material first. This kit is highly water-resistant, UV resistant, and can handle a wide range of temperatures, making it a reliable choice for saltwater and outdoor use. The curing time is reasonably quick, allowing you to use the repaired item after about 2 hours at room temperature, which is handy for field repairs. The kit includes a liquid sealant and a PVC mesh cord that adds strength for larger tears, although smaller repairs don’t require the cord.

Application is straightforward—just clean and dry the damaged area, apply the sealant (with or without cord), and let it cure without spreading it too thin. The glue remains flexible after curing, maintaining the inflatable’s shape and durability over time. One limitation is that the kit comes in a small 20 ml tube, so very large or multiple repairs might require more product. Also, it doesn’t work on all materials, so it’s best suited for those mainly dealing with PVC or PU inflatables. For those seeking a dependable, easy-to-use repair solution for inflatable water gear with good water and temperature resistance, AquaPro presents a practical option.
