Today's drywall is far more than just a backdrop for wallpaper or paint. On the surface, all wallboards may seem the same - reconstituted gypsum rock sandwiched between two sheets of heavy paper - but you now can choose drywall that serves many functions in Gapland, Maryland.

Before starting the project, though, you need to consider a few other factors. What is the wall made of, drywall or plaster? Does it need replacing or just repairing? If you want to move it, is it load-bearing? Knowing what you're working with will make the job go more smoothly.
