• #DRYWALL OVER LATH AND PLASTER HOW TO#

Back in the 1970's many lath and plaster homes added blown-in insulation.

In fact, in many older homes, the insulation can be crumpled newspaper. I like to stab at the lath with a square shovel, right next to studs. While plaster offers increased R-value over drywall (it actually has an R-value twice that of sheetrock) older homes with lath and plaster rarely contain adequate insulation. Theres no option to change its texture, so the only way you. Reinstalling old trim over newly drywalled walls seldom works out well either, as the walls were a different thickness previously. If you’re removing plaster and lath from both sides of a wall, do this: Completely strip one side of the wall, then attack the other side from behind. A big advantage lath and plaster has over drywall is its appearance.

Removing the old plaster and installing new drywall on the walls would also require removing all the wood trim a procedure fraught with hazards of its own, including breaking the trim, cracking and splitting it, and losing important elements. Find out how to deal with cracked plaster walls. I did a lot of work on the house about 8 years ago during which I removed some plaster-over-rocklath. Drywall vs Plaster: It is possible to cover lath (a thin flat strip of wood), and plaster walls with drywall or to replace them entirely in order to bring them. The usual result is noticeably uneven surfaces. Keep in mind that dust from plaster board and drywall. Drywall applied over old, uneven framing simply follows the studs and joists even if they're bowing, warped, or twisted. The old plaster and lath system enabled a plasterer to manipulate the thickness of the material making it thicker here, thinner there, accommodating framing discrepancies in order to create a smooth wall. Tear-away L-bead will be used on the edges to save on plastering ceiling-wall transition. I will also put an extra screw into existing strapping/joist intersections. Hanging new drywall over such an uneven surface is seldom successful. Since all plaster is solid (no moisture), I will go over the existing plaster with 1/2 drywall I will locate strapping and screw new drywall into the existing strapping. Like people, wood framing sags, twists, and warps with age. If the plaster walls in your home are unattractive or too costly to repair, you can cover them with drywall and start fresh. Removing the old plaster and lath would, along with generating tons of dusty, heavy debris that would need to be hauled away, leave exposed the original framing in the house.
