Drying time varies according to the type of compound as well as with the humidity and the amount of ventilation. Step 4: Apply two or three additional coats of compound, allowing complete drying between coats and feathering each coat over a wider area than the preceding one. Or you may embed paper drywall reinforcing tape in the compound immediately after applying it, and smooth with the taping knife.

Use a 5-inch taping knife to apply the compound in two stages, scratching the surface of the first coat so the next coat will bond better. Fill small holes with a setting-type joint compound (a powder that must be mixed with water) to almost level it with the surrounding area. Step 2: Mist the area with water first to prevent the dry plaster and wood from drawing moisture out of the compound too quickly. PLASTER WASHERS INSTALL
Tip: To secure loose plaster along cracks, install the screws on both sides and about an inch away from the crack.For large loose areas, install the washers in concentric rings, starting where the plaster is firmly attached and working in toward the loosest area in the middle. To avoid cracking the plaster, drill pilot holes for the screws with a 1/8-in.-diam., carbide-tipped masonry bit. Reattach remaining loose plaster with DP525 Plaster Repair Washers spaced a few inches apart. Step 1: Remove any small, loose chunks of plaster.

Real plaster has a look, feel, acoustic properties and often rich decorative detail that just can't be copied by its modern cost cutting substitute-paper-faced, gypsum-filled wallboard, or drywall. The old houses we love and live in are almost all distinguished by the pervasive use of plasterwork.
