My bathroom storage consists of some grotty old shelves - the top in particular gets very heavy wear, and is often wet.
Yesterday I slapped a load of chalk paint over it (Rustoleum Winter Grey - lovely, highly recommended). But it will stay lovely for about 5 minutes on the top. I was thinking of perhaps tiling over the top, but then wondered about a couple of coats of clear matt varnish instead.
What do you think? Is it possible to varnish over chalk paint? Will it change the colour a lot?
