Drywall Backer

Buttboard Drywall Backer from Trim-Tex installs behind butt joints in drywall between studs, helping to hide the joints and simplify panel layout on walls and ceilings. As the backer is screwed to each sheet of drywall, it pulls back on the edge, creating a tapered seam that the manufacturer says requires less joint compound to finish. Made from formaldehyde-free premium density OSB board, the backer works with metal and wood framing without the need for special tools. A case of 12 48-inch backers retails for $155. trim-tex.com
