LARGE MEDIUM GRAIN BRUSH 25cm

Function and technical context

This 25 cm long, medium grain brush is designed for cleaning, preparing and maintaining surfaces on boats, whether on hulls, bottoms, frames or engine and propulsion system components. Its medium granulometry makes it the ideal option when it is necessary to remove scale, surface rust, remains of aged antifouling or salt deposits without damaging the underlying surface, achieving a balance between abrasion capacity and protection of the material. Correct brushing before applying primers or anti-corrosion treatments is crucial to guarantee the adhesion and durability of the finish, preventing poor preparation from compromising watertightness or accelerating corrosion in critical areas of the hull and appendages.

When to replace this part?

The bristles of a medium grain brush lose effectiveness when there are permanently bent filaments, irregular wear in the work area or an obvious reduction in the ability to remove dirt and deposits. It is recommended to check the condition of the brush at the beginning and end of each nautical season, especially if it has been used in beaching or careening work where the effort on the bristles is greater. Replacing it preventively before undertaking beaching or hull preparation work ensures optimal performance and avoids having to repeat passes through a worn tool, which represents a real saving of time and effort in the workshop or shipyard.
