When self-furring metal lath is used for stucco, what does the 'self-furring' feature accomplish?
a.It holds the lath slightly off the backing so plaster can key fully behind the mesh
b.It eliminates the need for fasteners
c.It replaces the scratch coat
d.It makes the lath waterproof
Explanation
Self-furring lath has dimples or ridges that stand it off the backing a small distance, so the first (scratch) coat is pushed through and keys fully behind the mesh for a strong bond. It does not remove the need for fasteners, replace the scratch coat, or make the lath waterproof.
