I have wall with drywall in my basement with a bad job of wallpaper and panelling. I have removed the wall paper and pannelling only to find that the surface of the drywall is an eye sore. I would like to apply another layer of drywall - 1/2 in or 3/8 in . I noticed that the old drywall was screwed to a mix of 2 x 2 and 2 x 3 without any specific spacing. Where I cannot find wood to screw the new drywall to can I use an adhesive ?
Thnaks.
