Fix Walls in Lathe and Plaster

For lathe and plaster walls in older homes, a simple split can be fixed as above. If the plaster has separated from the wood lathe behind it then drill into the plaster alternating holes along both sides of the crack about 1 to 2 inches out. Use a wall glue from a hardware store in a caulk gun to squeeze into the holes. The glue needs to go in between the plaster and the lathe. Then patch the holes as indicated above.
