Expanded metal lath - diamond mesh plaster lath, formed from sheet metal cut into a diamond pattern, pulled to an expanded shape.Photo above: diamond pattern expanded metal lath stacked for sale at a building supply store. Van Den Branden and Hartsell explain that metal lath for plaster systems is divided into four groups with different properties for different applications:
#Metal lath crack#
Wall or ceiling or stucco crack patterns may follow the borders of metal lath segments, especially if the lath was not securely nailed. Metal lath was on occasion used also to support poured concrete ceilings (shown here) - unlikely to provide adequate strength for a thick pour unless additional reinforcement was used.ĭepending on building age we may find a mixture of multiple types of plaster support, wood lath, gypsum board lath, and metal lath. Our photo shows expanded mesh metal lath used as plaster lath support for ceilings and walls this material was also used on building exterior walls to support a stucco finish. Plaster of the same general formula as discussed in the two wood lath based installations above was later applied over expanded metal lath. This article explains plaster systems based on metal lath in building interiors.Īlso see STUCCO WALL METHODS & INSTALLATION for a discussion of exterior uses of stucco and metal lath.

Expanded Mesh Metal Lath for Plaster Walls & CeilingsĮxpanded metal lath has been widely used to support both interior plaster in buildings and exterior building wall stucco systems.
#Metal lath series#
In this article series we describe and discuss the identification and history of older interior building surface materials such plaster, plaster board, split wood lath, sawn lath, and expanded metal lath, Beaverboard, and Drywall - materials that were used to form the (usually) non-structural surface of building interior ceilings and walls. We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. We use building ceilings and walls as a photo and investigation guide to plaster and mortar lath systems. This article provides a photo guide to identifying and installing types of plaster support systems: metal lath, wire lath, etc. Installing plaster on expanded metal lath: We have no relationship with advertisers, products, or services discussed at this website.

It is suitable for use in both commercial projects and home improvements. Rib Form Lath is mainly used as a plaster backing on ceilings and walls. Diamond Mesh Metal Lathing is used for joint and crack reinforcement and refurbishment work. Metal lath is easy to fix and provides a secure key for many plaster and render applications. The lathing is manufactured in Galvanized and Stainless Steel, which can be used for internal and external applications. Renders on masonry, ceilings, suspended ceilings and timber framed buildings. Metal laths provide an excellent key for finishing materials such as plasters / PuRuiSe supplies expanded metal sheet fabricated steel lath for construction supplied in coils or sheet forms. The expanded mesh can be easily formed into coils or strips to form the structure framework. Expanded Metal Diamond Mesh Rib Lath for Plaster Render Finishes in Building Construction
