Hi have a basement doorway that I don't use want to leave the door but plasterboard it over its in the basement so want to make sure that it is done with proper plasterboard to avoid any damp issues

dont put the plasterboard on the floor keep it off the floor

hi there As well as keeping it off the floor you can also buy cement boards mainly used in bathrooms but a good strong board with good moisture resistance in case there is a condensation issue in the basement regards Joseph

Yes you can. But make sure that you are using right plasterboard. I suggest you weather defense plasterboard. Weather Defence is a revolutionary new external sheathing board, faced with water repellent material for superior weather protection. Strong, highly moisture resistant and A1 non-combustible. Weather Defence is a faster way to a weather tight building compared to traditional sheathing board products.
