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.

Air bubbles are a common problem faced by those who are mudding drywall. They occur when air becomes trapped under the layer of mud applied on the drywall. This can result in an uneven surface, making the wall look unsightly and difficult to paint. In this blog post, we will explain what air bubbles are when mudding drywall, how they occur when mudding over drywall that has been painted, and tips on how to prevent air bubbles in drywall mud.
What are air bubbles when mudding drywall?
Air bubbles are pockets of air that become trapped under the layer of mud applied to drywall. This can happen when the mud is not applied evenly or when it is not smoothed out properly. The result is an unsightly surface that is difficult to paint. Air bubbles are also a sign that the mud was not properly mixed or applied, which can impact the overall quality of the finish.
How do air bubbles occur when mudding over drywall that has been painted?
Air bubbles can occur when mudding over drywall that has been painted for several reasons. First, the paint may have been applied unevenly, leaving pockets of air underneath the mud. Second, the paint may not have had enough time to fully dry before the mud was applied. This can result in air pockets forming under the mud as it dries. Finally, if the mud is not applied evenly, it can cause air bubbles to form.
Tips on how to prevent air bubbles in drywall mud

1. Proper Mixing: It is important to ensure that the mud is properly mixed before application. If the mud is not properly mixed, air pockets can form, leading to air bubbles. Use a mixer to ensure that the mud is thoroughly mixed and that there are no lumps.
2. Smooth Application: When applying mud, it is important to ensure that it is smoothed out evenly. Avoid applying too much mud in one area or applying it too thickly. This can cause air pockets to form, leading to air bubbles.
3. Proper Drying Time: Allow the paint to fully dry before applying the mud. If the paint is not fully dry, air bubbles can form as the mud dries.
4. Use a Roller: A roller can help prevent air bubbles from forming by ensuring that the mud is applied evenly. Roll the mud on in a back-and-forth motion, ensuring that it is smoothed out evenly.
5. Avoid Over-Troweling: Over-troweling the mud can cause air pockets to form. Trowel the mud lightly, ensuring that it is smoothed out evenly.
6. Use a Compressor: A compressor can be used to remove air pockets from under the mud. Simply apply a small amount of mud to the wall and then use the compressor to remove any air pockets that have formed.
7. Sanding: Sanding the mud after it has fully dried can help remove any air bubbles that have formed. Sand the mud lightly, ensuring that it is smoothed out evenly.

In conclusion, air bubbles are a common problem faced by those who are mudding drywall. They occur when air becomes trapped under the layer of mud applied to the drywall. To prevent air bubbles, it is important to ensure that the mud is properly mixed, applied evenly, and allowed to fully dry before sanding. By following these tips, you can prevent air bubbles from forming and ensure that your drywall is smooth and ready for painting.
