Abrasive sheet KWB 851820 P120 Silicon carbide 5 pcs

The KWB 851820 abrasive sheet is a fibreglass-reinforced mesh sanding sheet with silicon carbide abrasive and a P120 grit. Supplied as a pack of five sheets (230 mm × 93 mm), it is intended for manual sanding tasks where effective material removal and reduced clogging are required. The open mesh construction helps prevent dust build-up on the abrasive surface, maintaining cutting performance when sanding render, paint, resin, acrylic or light rust.

Advantages

Fibreglass-reinforced mesh provides dimensional stability and resistance to tearing. Silicon carbide abrasive offers sharp, consistent cutting for a variety of materials. The mesh design reduces clogging, extending usable life during sanding of paints, resins and similar coatings. The P120 grit delivers medium-fine abrasion suitable for smoothing and preparation without aggressive stock removal.

How to use

Select an appropriate support such as a hand block or sanding pad sized to 230 × 93 mm, attach the mesh sheet securely and sand using even strokes across the surface. Apply moderate pressure and check progress frequently to avoid over-sanding. Clean the mesh periodically by tapping or blowing out dust to preserve the open structure and cutting efficiency. Replace the sheet when abrasive performance diminishes or the mesh is damaged.

Recommendations

Use P120 silicon carbide mesh sheets for intermediate smoothing and surface preparation on render, paint, resin and acrylic. For best results on delicate surfaces, test on a small area first and follow appropriate safety measures such as dust extraction and respiratory protection.
