Trying to patch a sandy textured painted interior wall finish, feels like 220+ grit sandpaper...
Tried some aquarium sand - too grainy & clumps together.
Wondering what other sands are worth a try?
From the feel I presume it needs to be angular not rounded grain, from the aquarium sand test the grain size needs to be a lot less than 1mm.
How fine is kiln dried sand in the sheds?
Any other thoughts appreciated!
