Why are we using purple drywall in this basement?
Because basements aren’t like the rest of the house.
Purple board has a treated core and paper facing that helps resist mold growth. It’s not waterproof (and it won’t fix an active water problem) but it adds a layer of protection when finishing a basement the right way.
The goal isn’t just to make it look good. It’s to build it so it lasts.
If you’re planning a basement renovation, details like this matter more than people realize.
