Metal vs Wooden Lath
In New York City, we encounter both wooden and metal lath, which are repaired differently. When replacing wood lath, the old lath is typically removed and new wood lath is installed by securing it in place with nails or staples to the framing. When replacing metal lath, the old lath may be removed or left in place, depending on its condition. If it is in good condition, new metal lath can be installed over it. If it is damaged or corroded, it will need to be removed and replaced with new metal lath.
