HARD GRAIN BRUSH 20cm

Function and technical context

The 20cm Hard Grit Brush is a cleaning and maintenance tool specifically designed for work on marine surfaces requiring intense abrasive action. It is mainly used for stripping tasks, removing biological fouling (barnacles, calcareous algae, mussels), surface rust and remains of aged antifouling on hulls, keels, propellers and submerged metal structures. Its hard-grain bristles allow effective mechanical pressure to be exerted without the need for aggressive chemicals in specific applications, making it a common element in beaching and seasonal preparation processes. The correct removal of deposits and degraded layers is essential before applying new coats of paint or protective treatments, since a poorly prepared surface compromises the adhesion and durability of any subsequent coating.

When to replace this part?

The bristles of a hard grain brush lose effectiveness when permanent deformations, flattening of the filaments or breakage of strands are seen, signs that the abrasive capacity has decreased significantly and cleaning performance is compromised. It is recommended to inspect the condition of the brush at the beginning of each season and after intensive beaching work, replacing it whenever the bristles show visible wear. Having a brush in good condition in the onboard maintenance equipment avoids having to postpone preventive cleanings and guarantees optimal results in each intervention.
