My husband and I wanted to install hot drywall all through our double huge mobile home. The old walls have holes and the previous owners did not do a good available job trying to cover them up (bumps, scratches). Also I can smell some nicotine, so we definitely want to lift this down and put new drywall on. It's a 3 bed/2 tub home, about 1100 sq.ft. What materials do we want for this project?

This have led to much frustration for me beside our home. I don't think I enjoy a 90 degree angle anywhere surrounded by this house...it's always lately a little rotten, and by the time I get to the other closing stages of something, that little bit has grown to a evident gap.

Unless it is in really, REALLY, fruitless shape, I would take the time and joie de vivre to patch and repair the existing. If you have one or two walls that are beyond repair, install 1/4" unmarked over the old. Unless you and your husband hold experience at this sort of thing, you will winding up up with worse than you hold. Fresh paint and time will get rid of nicotine smell. Just my assessment. Good Luck.
