Let's face it, who hasn't had a door knob swing into the wall and create a nuisance hole? We've all had some holes in drywall in our past, or maybe in our future. For those holes that are too small to require a new piece of drywall set in place with the Hyde Clips sold below, use the Wet & Set system. The patented patch is filled with a polymer activated by water. Cut the 5" wide patch to just an inch or so longer than the repair area, get the patch wet, set it in place and smooth it out. Let is set for 30 minutes, then cover with a thin layer of drywall mud. When the mud is dry, sand it smooth and you are ready to paint and forget that the hole was ever there.
