Then plaster is applied to the lath in thin coats using a trowel. First, the strips of lath are nailed to wall studs or ceiling joists. Lath and plaster walls are wall covered with 1-inch wide strips of wood nailed closely together followed by 3 thin coats of wet plaster. But due to its density, it blocks WiFi signals making wireless routers less effective. Plaster also has great sound deadening which is an advantage in a noisy home. It’s very hard to damage, dent or scratch compared to much softer drywall. The biggest being how strong and dense the material is. There are some big advantages to using plaster instead or drywall. It’s not used much in Modern construction, but many older homes still use it to stay more original. Once fully dry, it’s texture is a bit rough and it’s very dense.ĭrywall panels were invented in the 1950s to replace lath and plaster because they’re easier, faster and cheaper to install. When properly mixed it has a consistency like thick peanut butter and easily sticks to the lath. Plaster is made by mixing sand, and cement and/or lime with water. Ingredients are often added to the mixture to give it an extremely white color without requiring paint.

Once plaster dries, it can be painted or left it’s natural color. It can be finished by the installer to be extremely smooth or textured depending on the look the designer is going for. The plaster hardens over time, forming a strong bond between the lath and wall surface. As a final step, the plaster is carefully smoothed using trowels and a damp sponge. They then spread multiple thin coats of plaster over the wood lath to form a smooth wall surface. To do it, builders first nail thin wooden strips of wood closely together to the wall studs and/or ceiling joists. Strategic procrastination is the secret of period property ownership, as others here will attest.Lath and plaster is an age-old building technique used to finish interior walls and ceilings. Or if it is actually a lath wall, then scraping back a divot and applying a stainless penny washer and screw into the lath works well (typically used to preserve historic ceilings). If you do want to keep yourself busy, a simple fix is to drill a small hole through the detached area and inject adhesive or slurry plaster (assuming the plaster IS on stone).

The worst that could is that the area detaches and then you can patch replaster at that point. Unless it's a ceiling that may fall on you, nothing bad is likely to happen.

I have plenty of such areas in my house that have been fine that way for the 25 years we've lived here. However, the good news is that practical experience tells me to leave them alone. Thirdly, to answer your actual question, you are correct that walls plastered onto stone shouldn't sound hollow and that the cause is likely that the plaster has blown (detached from the stone or underlying coats). You would be amazed how many walls appear to contain turning machines.Though, our pedants would instead pick you up on the fact that plaster directly applied to stone walls would not need laths (these are substrates for bridging hollow areas, such as ceilings or stud walls). Secondly, congratulations on correctly spelling lath.
