Patching with Plaster Video

Chris Borovka from US Gypsum joins Bob explain about patching with plaster. The first job entails patching over an existing door opening. They've put some Imperial Gypsum base up to the existing door frame and patched the existing hole with diamond veneer base coat. Next they put pressure sensitive fiber tape, P-Tape, over it and bonded the entire existing surface. The use USG Plaster Bonder Pink as a bonding agent - it rewettens and re-emulsifies - and put the base coat of plaster over that. Where the wall meets the ceiling, they apply pressure-sensitive tape to the existing surface and butt it in while applying the first coat of base coat. The first coat provides a nice even scratch coat. The second coat should be applied while the first coat is still fully wet and serves to take out some the bad dips and dives and the trowel marks from the first coat leaving a nice smooth finish. The next day you they'll put the finish coat over it. Where the insulators drilled holes into the original walls, the plasters put the Plaster Bonder Pink around the inside of the hole and fill it in with the base coat. They've meshed over the top of that for extra security and then bonded over the whole surface. On the blue board, it's a different type of installation. Shreve applies one-coat over the joints to reinforce them and fill in the undulation that's left from the two end tapes from the butt joints. That sets up for about an hour and then it's ready for finish coat.
