Yes, a TV can hang on a plaster wall when the mount is lagged into framing. Hollow plaster with no stud behind the bracket is the failure mode.

The stucco article covers cement stucco over sheathing or block, including patio walls. This page is interior plaster on wood or rock lath: North Park, South Park, Golden Hill, Mission Hills, parts of Ocean Beach, and 1920s to 1940s bungalows countywide.

Plaster is not drywall

Drywall is a gypsum panel screwed to studs. You can miss a stud and still catch a toggle in the panel. Plaster is a brittle coat over wood lath or rock lath. A missed hole can spider a crack across a whole bay. Patching that crack is a plaster ticket, not a dab of spackle.

Wood lath is thin strips with plaster keys pushed through the gaps. Rock lath is gypsum board used as a plaster base in later pre-war and 1940s work. A stud finder can lie on both. Ask the quoting professional how they will confirm the stud: finder plus a small test, or by locating a known stud line from an outlet or trim.

CPSC advises securing TVs and furniture according to manufacturer instructions, including anchoring TVs that are not wall-mounted. No universal anchor load rating is approved on this site. Follow the mount manufacturer and the TV manufacturer. See CPSC Anchor It.

What the written scope should name

Wall type: plaster on lath, not “just a wall.” Mount type: fixed, tilt, or full-motion. See fixed or full-motion. Whether the cable will be fish through the bay or surface-raced. Whether a plaster patch is included if a hole misses.

Full-motion arms multiply the lever on the fasteners. That is a reason to hit two studs, not a reason to use drywall toggles in plaster.

If the wall sounds dead with no stud line where you want the TV, move the location or build out a plywood panel lagged into studs, then plaster-patch the perimeter. That is a carpentry-plus-mount ticket. Ask for it in writing. Do not treat a floating toggle as a stud.

What to photograph

One wide shot of the wall with the sofa or fireplace in frame. One shot of nearby trim, picture rail, or a cracked hairline so the pro sees the plaster condition. The TV box with the size on the carton. Any existing mount holes.

Above a fireplace is a separate heat and height problem. Use the fireplace post for that layout.

Confirm CSLB status. New cable through a wall can be an electrical permit question. Confirm with the building department that serves the address.
