I've got to remove a fair amount of tile adhesive off plaster now that
the tiles are off the wall. It's sticking like the proverbial to a blanket.

I'm not too fussed about creating dust so would a belt sander shift it?

I've found that a block plane can work very well for this.
Of course, the blade will need a complete resharpen, if you contact the
plasterboard.
(I used a Lidl 3.99/2 planes pack for this.)
