Finishing & Protection
Sanding Block
For everything a power sander is too aggressive for: edges, mouldings, small parts and between coats.
What it is for
For everything a power sander is too aggressive for: edges, mouldings, small parts and between coats. This guide covers what the tool does, the specification points that actually change your results, and how to use it without damaging the work or yourself.
Where it fits in the build
This is a finish stage tool in the Finishing & Protection category. Smooth, colour and seal the completed piece.
Using it well
- Wrap the paper tight and clamp the ends so it does not pull loose mid-stroke.
- Sand with the grain on flat faces, and use a block rather than fingers to keep edges crisp.
- Between finish coats, sand very lightly with 320 or higher just to knock back dust nibs.
Compatible materials
Materials this tool handles without compromise. Where a material is not listed, check that the tool is rated for it before committing to a cut.
- Hardwood
- Softwood
- Plywood
- MDF
Reference sample in 3D
The model above is a real pine reference block rendered in the browser. It is simulated from a height field rather than photographed, so you can rotate it to see how light behaves across the grain, the end grain and the edges. Drag it, or use the view buttons to look at the top face or the end grain in isolation.
Reading how light falls across a board is the fastest way to judge whether a surface is flat. That is the same judgement you make with a hand plane or a sander, and it is much easier to see on a rotating model than on a static photo.
