Over polished plater

Do you sand shiny new plaster before you apply a mist coat with a 240 grade paper.

2 Answers from MyBuilder Plasterers

Under no circumstances do you rub bare plaster before mistcoat, you will end up with scratch marks. Apply the mistcoat before any rubbing or filling, it will dry ok even on polished plaster.

New plaster should have a. It's coat applied first and if done properly should not really require this
