Marine-Grade Adhesives & Sealants for Boats

With our professional strength bonding adhesives for boats, you can prevent leaks that can cause structural damage and sinking. Choosing the right marine grade sealant and adhesive tube can seem daunting, but we’re here to help. Our selection of products is full of easy application adhesives and sealants for boats. With sealant options such as silicone and polyurethane, you can quickly seal up wood overnight. Some sealant options can be noticeable if they get on the surface, but they can also be sanded and painted to prevent them from being noticeable to the eye. If you spend large amounts of time out on the water, you should keep marine general adhesives and sealants handy for those unforeseen emergency situations.
