I had 3 pine doors fitted and clear stained but we keep getting splinters off one door. I've been onto the fitter but no joy so I'll sand it down myself. Do I use sandpaper sheets or will I need a sander? tia.
Either. A power sander is quicker, less hassle, but will raise a lot of dust. If you do as I say and not what I do you'd use a face mask. But doing it by hand if you don't mind the time taken and effort, works too. (Personally I'd invest in a sander. You may opt to finish off by hand anyway.)
