Painting Lath and Plaster Walls: A Guide to Repairing Peeling Paint

When it comes to painting lath and plaster walls, there are several steps you can take to ensure a smooth and successful process. In this article, we will explore the best ways to repair peeling paint on these types of walls.

First, it's essential to understand that cracks in lath and plaster walls will continue to move over time. To fill tiny cracks, use paintable caulk. For larger cracks, apply spackle or mud compounds, but be sure to sand them smooth when dry.

If you're dealing with mold on your plaster wall, start by applying a stain-blocking primer such as Kilz Premium or 1-2-3. This will help prevent the mold from spreading and ensure that any future paint jobs are successful.

Before painting, remove any loose plaster using a putty knife. Be prepared for some cracking, which you can patch up with spackle after sanding smooth. If the plaster wall is still firm but has separated from the backing lath, simply reattach it with drywall screws.

Despite the extra effort required to paint plaster walls, they are often worth saving due to their unique character and potential cost savings compared to modern drywall. To get started, prime any bare plaster or drywall with a basic drywall primer. For old plaster, avoid using paint-and-primer-in-one products, as they may not provide the best results.

Some stains can still bleed through after several years, so it's essential to use a stain-blocking primer for water-stained walls. To find the best primers and paints for your lath and plaster walls, read our top recommendations below.

In conclusion, painting lath and plaster walls requires some extra effort, but the results are worth it. By following these simple steps and using the right products, you can achieve a beautiful and durable finish that will last for years to come.
