How Does Self-Furring Metal Lath Installation Work?

When it comes to achieving a durable and smooth finish in plastering, self-furring metal lath is an excellent choice for both professionals and DIY enthusiasts. Not only does it provide an ideal surface for plaster to adhere to, but it also effectively prevents cracking and assists in controlling moisture. In this blog, we will delve into the installation process of self-furring metal lath, focusing on techniques that ensure a solid foundation for your plasterwork.

What is Self-Furring Metal Lath?

Self-furring metal lath is a type of metal framework made from cold-rolled steel or galvanized steel. Its unique design features little “fins” or ribs along the length of the lath. These ribs protrude outward, creating a gap between the lath and the wall surface. This space allows plaster to flow behind the lath, forming a strong bond that enhances the sturdiness of the wall. Such bonding is crucial in reducing the likelihood of cracking and ensuring longevity.

Preparing the Installation Area

The success of the installation hinges on proper preparation. Before beginning, make sure the wall surface is clean, dry, and free of any obstacles. Remove old plaster, dust, and loose debris. If the wall has noticeable irregularities, consider using a leveling compound to even out the surface. This step will ensure that your metal lath adheres perfectly and provides a uniform base for plaster application.

Gathering Your Tools and Materials

Before you commence installation, gather the necessary tools and materials:

• Self-furring metal lath
• Galvanized nails or screws
• Wire cutter
• Measuring tape
• Level
• Hammer or power drill
• Plaster or stucco
• Safety goggles and gloves

Cutting the Metal Lath

Once you have your materials, the next step is to cut the self-furring metal lath to the desired size. Using wire cutters, measure and mark the lengths as needed, ensuring that your cuts are straight. For corners or edges, you may need to tailor the lath carefully to fit the contours of your structure. Precision at this stage will make the installation more manageable and effective.

Installing the Metal Lath

Begin your installation by positioning the metal lath against the wall. It’s essential to start at one end and work your way across systematically. Using a level, ensure that the lath is placed straight and even. The self-furring fins should face outward, away from the wall surface, to create the necessary gap for the plaster.

Fastening the lath correctly is crucial. You can use either galvanized nails or screws, depending on your preference and the wall material. Space these fasteners approximately every 16 inches along the edges and throughout the center of the lath sheets. Make sure to drive them in firmly, ensuring that the lath is securely attached to the wall without sagging.

Pay special attention when working around windows and doors. Here, you may need to trim the lath to ensure it frames these areas properly. It’s often a good idea to allow a slight overlap at the edges to maintain a robust installation.

Check for Alignment

After fastening the lath, it’s essential to double-check that everything is aligned correctly. Use a level again in various sections of the wall. This step may seem tedious, but a uniform installation decreases the chances of wavy or uneven finishing when applying plaster.

Applying Plaster

Once the metal lath is installed, the next stage is to apply the plaster or stucco. Mix your plaster to the manufacturer’s specifications, achieving a smooth and workable consistency. Using a trowel, apply the plaster onto the lath, ensuring it fills the gaps created by the furring ribs. Work the plaster into the metal mesh, pushing it through the lath to maximize adhesion.

Start with a scratch coat to establish a solid initial layer, then follow with additional coats as necessary to create the desired finish. A trowel or float can be used for smoothing and refining the surface as you go.

Finishing Touches

Once your plaster has been applied, allow sufficient time for it to cure according to the manufacturer's guidelines. After curing, you can proceed to polish or paint the surface, bringing your project to completion. The result will be a durable, sturdy, and beautiful wall that stands the test of time.

Conclusion

Installing self-furring metal lath may seem daunting at first, but with careful planning and execution, it can lead to impressive results. By following the methods outlined above, you'll create a robust foundation for plastering that ensures a flawless finish. Whether you're a professional contractor or a proud DIYer, mastering this technique can elevate your projects and provide surfaces you'll be proud to display.
