TV Mounting Coast Huntington Beach: TV Mounting on Lath-and-Plaster Walls in Huntington Beach
TV Mounting Coast Huntington Beach covers TV mounting on lath-and-plaster walls in Huntington Beach's older beach cottages — the small pre-war and early post-war homes near downtown and the older streets inland from the pier — where the plaster is hard and brittle, the studs hide behind wood lath, and every hole is drilled to keep the wall from cracking.

How a plaster wall is built
| Layer, outside to inside | What it is | What it means for drilling |
|---|---|---|
| Finish coat | Thin, hard lime or gypsum plaster | Chips if drilled fast with a dull bit |
| Brown and scratch coats | Thicker plaster pressed into the lath | Holds poorly on its own |
| Wood lath | Narrow strips nailed across the studs | Hides the studs from many stud finders |
| Studs | Solid lumber, sometimes at irregular spacing | The only thing the mount should rely on |
Finding studs behind lath
Magnetic finders that locate the lath nails, a series of small test holes behind the plate's footprint, and the outlet boxes (usually fixed to a stud) together find the framing. Older cottages do not always have studs at a regular 16 inches, so each one is confirmed before the plate is marked.
What the numbers show
- Plaster coat Hard plaster can crack around a hole; it is drilled slowly with a sharp bit, often through painter's tape.
- Wood lath strips Thin horizontal strips nailed across the studs hold the plaster; they are not a fastening point.
- The stud behind Studs are found with a deep-scan finder or a magnet on the lath nails, and confirmed with a small test hole.
- Longer lag bolt The bolt is long enough to pass through plaster and lath and still reach well into the stud.
- Pilot hole A pilot hole through plaster, lath and into the stud keeps the wood from splitting and the plaster from cracking.
Drilling without cracking
- Sharp masonry or carbide bit for the plaster, then a wood bit for the stud.
- Low speed, no hammer setting so the vibration does not loosen the plaster keys behind the lath.
- Pilot holes first, then the lag bolt driven by hand or at low torque.
- Patching of test holes with plaster patch, not spackle alone, so it does not shrink.
Old plaster rewards patience: slow drilling is the difference between four clean holes and a cracked wall.
Wires on a plaster wall
Fishing cables inside a plaster wall is slower than in drywall because of the lath and the plaster keys. A slim paintable raceway, a console placed directly below the TV, or a route through an adjacent closet are common choices; in-wall rated kits work where a clean stud bay can be found.
What the numbers show
- Raceway channel A slim two-part channel is fixed to the wall; the cables lie in its base and the cover snaps on.
- Cables inside Signal cables and the TV's own power cord run inside to an existing outlet; no new wiring is added in the wall.
- Paint to match The cover takes paint, so it reads as part of the wall.
- Straight run A straight vertical run from the centre of the TV to the outlet looks deliberate and is easy to remove later.
TV Mounting on Lath-and-Plaster Walls — common questions
How much more does a plaster wall cost?
About $30–$50 on top of the base range in 2026, so roughly $139–$199 for a 32–49 inch TV on lath and plaster.
Can a plaster wall hold a large TV?
Yes, when the mount is fastened into the studs behind the lath with bolts long enough to reach solid wood.
