Can you sand wood too smooth?

If wood gets over-sanded in one spot, it starts to become uneven, with a distorted sort of appearance. This can happen to even the most experienced woodworker. Usually this starts simply by attempting to sand out a discoloration, defect, scratch or gouge.

What happens if you sand wood too much?

If you sand wood past 240 grit sandpaper, the wood dust becomes so fine that it starts clogging the pores of the wood. This prevents stain and finish from soaking into the wood properly, risking a poor finish job. Alternatively, if you sand too much in one single spot, you might create a divot in the wood.

How do you know when to stop sanding?

So what's the right amount? The best way to know when you're done sanding is to scribble a light pencil line across your wood before you start. Once the line is gone, move up to the next grit. Repeat up to the highest grit sandpaper, then wet your wood with mineral spirits to confirm there are no remaining marks.

What happens if you sand stained wood?

This coarser type of sandpaper leaves a different scratch pattern on the surface of the wood. The aggressive scratches of the sandpaper leave more scratches, so when you add stain on top of that, the pigment particles in the stain have more places to lodge and add that darkening effect.
