I had a brick wall plastered this week - plasterboard then skimmed with plaster on top. I want to decorate this room next week as I have the week off, and wanted to paint over the plastered wall. I know I need to wait til its completely dry, but how long does this take and how do I know when it is dry?
I bought some plaster sealer from B&Q to use first before painting over with dulux emulsion - does using this speed up the process or not?
Thank you
