Sandpaper loads up on soft pine, on old enamel, and on glue that has squeezed out of a joint. A cabinet scraper cuts a shaving instead of grinding that dust into the grain.
Where it earns its place
- A paint ridge sits along a skirting or an architrave after a sloppy cut-in.
- Glue has dried proud of a joint, and sandpaper would smear it into the pores.
- You want the face flat enough to take a finish without rounding the arris.
The hook is the cutting edge
A rectangular cabinet scraper, such as the Pax set, is the usual shape for a flat face. A burnisher turns the edge into a small hook. Without that hook the scraper only polishes. The Accu-Burr burnisher is in the catalogue if you do not already own one. Follow the maker’s notes on the card for the steel you bought — hook angle is not the same on every scraper. Both are under scrapers.
Hold the scraper with both thumbs in the middle, bow it slightly, and push or pull at a low angle. A bright curl means the hook is working. Dust means the edge is dull, or you are too upright.
A scraper will skate on a thick, rubbery acrylic if the paint has not fully cured. Let the paint harden, then take the ridge. It is a finishing tool, not a way to remove a failed coating from a whole wall.
