3/31/2024 0 Comments Hanging on plaster and lath wallsDrill a small pilot hole to confirm stud location (behind the lath), then screw directly to that. If you are hanging something heavy or something that will otherwise require maximum support, find a stud. Studs are the best places to attach a screw, as they provide by far the most structural stability. This is not a good area to insert picture hangers as there is not really any structural value to the plaster between pieces of lath. If your drill bit pops through the brown coat in to thin air, then you have hit a spot between laths. There is the initial resistance of the thin hard top coat, then the (usually) quick vaporization of the brown coat, followed by coming up against the lath, and possibly thereafter a stud (lath is only around 1/4 inch thick). When drilling through plaster and then lath, the different layers are easily recognizable by the feel of the drill. What We Encounter Drilling in to Plaster & Lath Your standard plaster & lath wall generally has 4 basic components that you may encounter: studs (vertical framing lumber), lath (wooden strips running horizontally, nailed to the studs), scratch & brown coat plaster over the lath (the crumbly stuff, often including animal hair or other fibers to help hold it all together), and the thin very hard top coat of plaster. The standard ‘picture hook with a nail’ simply does not work.įor hanging pictures, I generally favour plugs & screws with a special hook that gets screwed to the wall in any event, but even still, plaster & lath can be annoying even for drilled plugs and screws. Got the plaster & lath blues? As you likely already know if you are reading this, plaster & lath walls pose a greater challenge than drywall for otherwise simple tasks such as hanging a picture.
