Framing & StructuralCâu 353 / 700
When metal lath for three-coat stucco is fastened to a wood-framed wall, how far should the fasteners penetrate the framing?
a.Just into the sheathing
b.No penetration is needed if the lath is tight
c.Only into the WRB
d.Into the studs or supports far enough to hold the lath securely (commonly at least about 3/4 to 1 inch)
Giải thích
Lath fasteners must reach into the studs or solid supports enough (commonly on the order of 3/4 to 1 inch) so the lath and the heavy wet plaster cannot pull loose. Fastening only to sheathing, to the WRB, or relying on tight lath without penetration will not hold the plaster.
