Expanded Metal Lathing

Expanded Metal Lathing is manufactured from prime quality steel sheets that are slit and expanded to form small diamond shaped openings (over 10,000 per square yard). This large number of openings provides more plaster keys than any other type of lathing material. This allows for better stucco bonding in either pumped or troweled applications. Each sheet has square ends and smooth parallel edges for fast, easy handling and installation; and can be readily bent for curved surfaces.

Expanded Mesh metal lathing is manufactured to BS1369: Part 1: 1987 in a range of weights.

It provides an excellent key for finishing materials on masonry, ceilings, suspended ceilings and timber frame buildings. This material is designed mainly as a background plaster reinforcement to minimize cracking.

Plasterwork on metal lathing offers a smooth, hygienic, monolithic surface giving it complete access to decorating. It also provides sound insulation and fire protection.

Commercial applications include partitioning, suspended ceilings and encasement of steelwork.

INSTALLATION GUIDE

• Fix LWM from support to support.
• Timber joists – Nail at angle away from centre to tighten up the lath. Repeat every 100mm (4”).
• Steel channels – Use wire ties. Fixing sequence is same as in timber joists.
• Overlapping – Sheets ends should overlap 50mm (2”) on bearers, and side laps should not be less than 25mm (1”). All laps should be wired together at 150mm (6”) intervals.
