The gypsum lath was paper covered, similar to drywall. Gypsum lath panels or boards came in various sizes, but was typically 16 inches by 48 inches. The gypsum lath was covered with one or two coats of plaster and the total thickness of the system. The advantage of using Durabond (over a traditional plaster) is that it sets up as hard as plaster but dries quickly, so if Im in a hurry I can apply a second coat the same day. Plaster is brutal on sharp tools, so I use two different cutting implements for this process. First I use a standard utility knife, to separate the paint and the top layer of plaster. As long as the crack survives the scrape-out without crumbling into chunks, it can be filled and taped much the same as if it were a drywall joint. Before breaking out the mud, however, its important to verify that the plaster is firmly attached to. Pilot holes a couple of inches away from each side of the crack and fasten the washers using 2-in. screws. Setting compound (Durabond 90) is forced into the crack from both sides to ensure all voids are eliminated. I use a setting-type joint compound like Durabond 90 to fill the gaps, mixing up only as much as I can apply in about an hour. After packing the joint with compound, I cover the seam with fiberglass mesh tape, and follow up with a. In some applications, the combustibility of this material may be an issue. Most paneling does not take paint or wallpaper as readily as drywall or plaster. Redecorating paneling can be difficult without removing it. For example, in rough order walls were finished using hand-split wood lath, sawn lath, expanded metal lath, gypsum board lath, and drywall. These materials are easy to recognize and identify, as we illustrate here. Paneling on Interior Walls Wall paneling may be veneered plywood, asbestos-cement board, veneered particle board, or solid wood. It is available in many forms and appearances, from a simple and inexpensive 1/8 inch sheet of 4x8 plywood, to an intricate, highly finished hardwood system, found. Plaster washers ( m ) are wafer-thin, perforated discs which are designed to reattach loose, but otherwise sound plaster to the framing without causing cracks. After locating the centers of the framing members, I drill 3/32-in. The drawing is provided courtesy of Carson Dunlop Associates and appears in their Illustrated Home. Click to enlarge any image At.
