Nautical fillers are a category of products whose main function is to obtain a smooth and uniform surface, eliminating imperfections due to structural modifications of the hull, leveling of the boat decks, or small damages.
Boat fillers, preceded by the appropriate primers, are used on various materials, including fiberglass, wood, and metal, creating a strong and durable bond.

Thanks to their low specific weight, they do not significantly increase the weight of the boat, helping to limit fuel consumption.
