Diamond Mesh Lath

A Galvanized Expanded Steel Plaster/Stucco Base

A superior multi-purpose expanded steel base widely used for interior and exterior plaster and stucco reinforcement. The flat surface is easily cut and formed for use with flat or contoured surfaces. It is an excellent base for stone, spray on structural fireproofing, ornamental work, and under ceramic tile. Expanded metal lath is formed from sheet steel that has been slit and expanded to form thousands of plaster “keys” per square yard. Its time proven exceptional strength and flexibility makes it the preferred metal base requested by contractors and design professionals.

Diamond mesh metal lath is available with or without a Grade-D asphalt paper-backing breather sheet.
