Fluted 20-Grit Wall Rubbing Brick

Approx. 10 cm × 6 cm × 4 cm; weight ~350 g; abrasive layer: fluted silicone carbide (20 grit); handle: robust red plastic; colour-coded for quick identification on busy sites. The directional fluting aligns with natural hand motion — enhancing cutting efficiency during horizontal and vertical strokes. Silicone carbide’s thermal stability prevents degradation even during extended use under UK spring/autumn ambient conditions (5–18°C), where rubber-bonded alternatives may stiffen or crack. Commonly used by plasterers prepping dot-and-dab backgrounds, bricklayers adjusting pointing profiles, and decorators removing efflorescence or paint overspill from textured façades — all without damaging base substrate integrity.
