Watertite is a fast-drying epoxy filler for use on fibreglass, metal and hardwood constructions. Its non-shrinking, highly water-resistant formula makes it suitable for repairing osmosis damage.
Two-component epoxy filler for repairs and fairing
International Watertite is a high-quality two-component epoxy filler designed for filling, repairing and fairing surfaces above and below the waterline. Thanks to its water resistance and excellent adhesion, it is suitable for use on boats made of polyester (GRP), steel, aluminium and wood.
The filler is designed for quick and easy application and can be applied in thicker layers without sagging. Once cured, it forms a hard, water-resistant, easy-to-sand surface that provides an ideal base for subsequent coatings, primers or antifouling systems.
Watertite is particularly suitable for repairing minor damage, dents, cracks and irregularities on the hull. Due to its low water permeability, it is also commonly used as part of osmosis protection systems on polyester boats.
The product cures quickly and allows further work within a short time, helping you complete repairs and surface preparation before painting faster.
