REPAIRING AND RESURFACING PLASTER
When Avalanche Plastering resurfaces existing plaster, we follow
this process. You can leave all the baseboard, window and door trim
in place. We will:
- Remove really loose plaster.
For ceilings, we first hang wire mesh. This eliminates the need to remove a lot of slightly loose plaster, which also minimizes the release of potentionally lead-contaminated paint. (We vacuum up an dust that is released.)

- We apply a white-pigmented shellac primer to all exposed lath, plaster and painted surfaces. This is done as a precaution to prevent the old paint from reactivating and delaminating, while keeping moisture out of the old wood lath and framing.
- For ceilings, we apply the scratch and brown coats. For walls, we coat the entire surface in USG Durabond™ "hot mud." This
seals up the surface and provides an excellent base for the plaster.
- While the hot mud
is still wet, trowel in nylon screen over the
entire surface to tie the whole ceiling or wall together and prevent cracks.
- Finally, plaster with a two coat veneer plaster system.
