How to Cover Lath and Plaster Walls

Lath and plaster walls are a common feature in many old buildings, but they can be prone to damage and wear over time. When it comes to making repairs, it's essential to use the right materials and techniques to ensure that the integrity of the wall is maintained. One popular method for repairing lath and plaster walls is using Expanded Metal Lathing (EML) instead of traditional plasterboard.

The benefits of using EML are numerous. For one, it can be applied in rows, making it ideal for small repairs. Additionally, it can be cut to shape using tin snips, allowing for a more precise fit around the hole or area being repaired. Once cut, the EML can be fixed with galvanised staples, which helps to maintain the structural integrity of the wall.

Another advantage of using EML is that it can be used in conjunction with traditional plastering techniques. By applying a coat of PVA adhesive to the new plasterboard and edges of the existing plaster, you can create a solid bond between the two surfaces. This makes it easier to apply skim plaster over the top, which will help to fill any gaps or unevenness.

Of course, there are also some challenges associated with repairing lath and plaster walls. One of the biggest issues is dealing with the porous nature of old plaster, which can make it difficult to get a smooth finish. To combat this, you can apply a coat of PVA adhesive to the surface before applying the skim plaster.

In addition to using EML and traditional plastering techniques, there are also other materials that can be used to fill gaps around the edges of the repair. Depending on the size of the gap, you may need to use polyfiller, one-coat plaster, or flexible filler. Once the gaps have been filled, you can apply skim plaster over the top to create a smooth finish.

Overall, covering lath and plaster walls requires some patience and attention to detail, but with the right materials and techniques, it's possible to achieve professional-looking results. Whether you're a DIY enthusiast or a professional builder, using EML and traditional plastering techniques can help you to restore your wall to its former glory.
