Mudding Over Paint

As a professional drywall company, Maple Grove Drywall Pros has years of experience in all aspects of drywall installation and repair. One of the tasks we often encounter is covering painted drywall with mud. Whether it's for repair work or to create a smooth surface for texturing, applying mud to painted drywall can be a bit more complicated than applying it to raw drywall.
Here's the proper way to cover painted drywall with mud:

1. Clean the surface: Before applying mud to painted drywall, it's important to make sure the surface is clean and free of any dirt, dust, or debris. A damp cloth can be used to wipe down the surface, or a vacuum can be used to remove any loose particles.
2. Sand the surface: Sanding the surface of the painted drywall will help to rough up the surface, allowing the mud to better adhere to the paint. Use a fine-grit sandpaper and sand in a circular motion, making sure to remove any high spots or rough areas.
3. Apply a bonding agent: Because paint can create a barrier between the mud and the drywall, it's important to use a bonding agent to help the mud stick to the surface. Simply apply a thin, even layer of bonding agent to the surface and allow it to dry completely before moving on to the next step.
4. Apply the mud: Once the bonding agent is dry, it's time to apply the mud. Start by applying a thin, even layer of mud to the surface, using a taping knife or drywall trowel. Be sure to cover the entire surface, including the seams and corners, and work the mud into the surface to ensure a good bond.
5. Sand the mud: After the mud has dried, use a sanding block to sand it down to a smooth surface. Sand in a circular motion, making sure to remove any high spots or rough areas. Be careful not to sand too aggressively, as this can cause the mud to crack.
6. Repeat steps 4 and 5: Depending on the thickness of the mud, it may be necessary to repeat steps 4 and 5 several times to build up a thick enough layer to cover the surface. Make sure to allow each layer to dry completely before applying the next.

By following these steps, you can ensure a proper application of mud to painted drywall. Keep in mind that applying mud to painted drywall requires patience and attention to detail, but with the right approach, you can achieve a smooth, even surface that is ready for texturing or painting.
