The K220 grit provides a fine finish and helps remove minor imperfections while preserving surface integrity for subsequent painting or wallpapering.

Advantages

The hook-and-loop backing enables quick attachment and replacement on compatible Ø225 mm sanding heads. The fine K220 grit balances cutting capability and surface refinement, helping to reduce the need for repeated passes and minimizing dust generation compared with coarser grits.

How to use

Select a compatible Ø225 mm sanding head with hook-and-loop fastening on your drywall sander. Ensure the work surface is dry and free of loose material before sanding. Attach a Bosch Expert C470 disc by aligning and pressing it onto the sanding pad until the backing is fully seated. Operate the sander at the manufacturer-recommended speed, using light, even passes and maintaining consistent contact pressure to avoid gouging. Replace the disc when wear reduces cutting efficiency or when the abrasive surface becomes clogged.

Usage recommendations

For best results, begin with the K220 grade for final finishing steps after coarser grits have been used to remove major imperfections. Use appropriate dust extraction and respiratory protection when sanding drywall to reduce airborne dust. Store discs flat and away from moisture to preserve abrasive performance.
