Rib Lath

Rib lath is a reinforced metal sheet that forms a strong backing layer for plaster or render finishes. It features a ribbed profile that locks the render or plaster firmly in place, helping to minimise cracks and movement.

What Is Rib Lath Mesh?

Rib lath mesh, often referred to as Riblath, is an expanded metal sheet featuring raised ribs that enhance rigidity and strength. Manufactured from galvanised or stainless steel, it is ideal where direct plastering is not suitable.

This mesh ensures there is firm mechanical bonding between plaster or render layers and their substrate, enabling them to key in properly and stay firmly in place. It provides stable support across uneven backgrounds, framing systems, and curved sections.

What Is Rib Lath Used For?

Builders typically use metal lath mesh for the following applications:

• As a plaster or render backing on ceilings, partitions, and masonry walls.
• To support render applied over insulation sheets or lath-and-plaster ceilings.
• To reinforce curves and arches where traditional boards can’t fit.
• As a carrier in fireproofing and acoustic coatings.

Its rigid build makes it easy to fix directly to timber, metal, and masonry using nails, screws, or wire ties.

Benefits Of Rib Lath Mesh Sheet

Here are some benefits of laying ribbed mesh lath:

• Provides a firm, stable base that maintains integrity once render or plaster is applied.
• Helps prevent cracking.
• Lightweight and easy to cut or shape to fit complex areas.
• Ensures a uniform render layer across complex or uneven areas.
• Performs well on flat and curved backgrounds.
• Delivers lasting resistance to corrosion.

Secure the rib lath mesh sheet to the substrate with suitable mechanical fixings or wire ties. The mesh should be aligned vertically for walls and perpendicular to joists on ceilings. Ensure the sheets overlap at sheet edges by at least 25mm.

What is rib lath used for?

It’s used as a plaster or render carrier on walls, ceilings, arches, and other uneven surfaces. Riblath is also a practical solution for surfaces where traditional plasterboard cannot be applied. It creates a smooth, crack-free finish and improves adhesion and stability on surfaces.
