305mm scrub, Polypropylene block, filled very stiff Polyester Resin Set.

The Deck Scrub is better for spot-type cleaning on slightly less even surfaces, and for smaller areas where soiling is likely to be harder to remove. This is because the filaments will give more easily to reach dips, and there are a lot more filaments to the square inch, allowing more intense cleaning.

Salmon Products has developed a very effective optional improvement in brush filament retention, where each tuft is stapled into the brush back with food grade stainless steel staples in the normal way, and then Epoxy resin is floated into a recess on the face of the brush.

The resin permeates the bottom of the tuft hole, covering the filaments and staples as it goes. The resin seals the face of the brush and makes the chance of a filament pulling out extremely remote, and inhibits the accumulation of dirt or moisture in the tuft holes.
