Use a sanding block
Alun Machin
The most basic way is to use an abrasive sheet wrapped around a cork block. And there’s a simple trick to ensure the full sheet is maximised to avoid wastage…
1. The lower the grit, the courser the abrasive paper and the number is always marked on the back of the sheet.
For restoring furniture, start with a course grit. 80-grit is good for removing paint or varnish and doing a rough once-over.
Then use 120-grit to clean up the surface. For working with clean, dressed timbers, start with this rather than 80.
Follow with 180-grit to smooth the surfaces, round-over the edges and corners. Then paint or varnish now.
Using 240-grit gives a silky finish. I use it to lightly run over paint or varnish before applying the final coat.
If waxing, finish with 300 or 400-grit before applying a few coats.
2. To use the sheets with a cork sanding block, always fold them in half lengthways and tear as straight as possible.
3. Position the block at the end, hold the paper against it to fold over.
4. Fold the paper onto the block firmly and crease the edges to help hold it in place.
5. Hold the loose edge of the paper against the block while sanding. When the paper becomes worn, unfold the block to reveal the un-touched layer, refold and continue.
