Glue, sealant and boat waterproofing

Adhesives and sealants are repair products commonly used on boats to fill cracks and holes in the hull that may occur over time during navigation. This type of product can be used with or in addition to other boat tools . They are available in different shapes and can be adapted to the materials used in the boat's construction. It's important to regularly check the condition of the boat's hull for any cracks or leaks. If a crack or leak is detected, it should be repaired immediately to avoid serious damage.

Adhesives are used to repair leaks and cracks. They are available in different types, such as polyurethane-based adhesives, which are very strong and can be used on many materials.

Sealants are used to fill cracks and holes in the boat's hull. They are available in various forms, such as fast-curing sealants, which harden quickly once applied. They are often used in combination with an adhesive to reinforce the repair.

Rubber or silicone gaskets are used to seal cracks and expansion joints between different parts of the boat, such as portholes, hatches and deck joints. They should be applied in a watertight and water-resistant manner.
