How to Apply Mud for a Textured Ceiling

If your ceiling is looking dull, cracked or otherwise in need of refinishing, you have other options than simply painting. A more interesting and decorative choice is to use mud to give the ceiling a fun, yet elegant textured look. You could hire someone to do it for you or even rent a popcorn splatter machine, but either way would be costly. Try using a rough sea sponge instead, where the only cost is the supplies.

Things You'll Need

• Hammer
• Cordless drill
• Sanding block
• Medium-grit sandpaper for block
• Face mask
• Painter's tape
• 5-gallon pail of mud
• Mud pan
• Mud knife
• Roughly textured sea sponge
• White painter's caulk
• Caulk gun
• Utility knife
• Rag
• Paint
• Roller
• Tray
• Small paintbrush or edger

Instructions

1. Prepare the surface of the ceiling by removing anything that sticks out. If there are small nails remove them with a hammer, or tap them in if they are they are meant for holding up the ceiling boards. If there are screws remove them unless they too are holding up the ceiling boards, in which case you'd want to countersink them 1/8 inch.

2. Use a sanding block with a medium-grit sandpaper to remove any burrs or ridges in the ceiling, including those from peeling paint. Wear a face mask when sanding.

3. Use painter's tape to tape off the top edges of the walls where they meet the ceiling. Do this so that your walls do not get mud on them, which will damage the finish of the paint or end up ruining the wallpaper.

4. Fill your mud pan with mud. Apply a layer of mud that is ¼ to ½ inches thick to a quarter of the ceiling. Apply the mud using a large mudding knife. You do not want to apply the mud to more than one-fourth of the ceiling at a time as the mud dries fairly quickly. In order to get the textured effect the mud must still be wet and pliable.

5. Use a rough sea sponge to dab at the ceiling repeatedly, where you have applied the layer of mud. Once you have completely textured the mudded area go ahead and apply the mud to another quarter of the ceiling. Use the rough sea sponge to create the texture in that area, and repeat steps 4 and 5 until the entire ceiling surface has been mudded and textured.

6. Remove all of the painter's tape from the top edges of the walls that meet the ceilings in the room. Ready a caulk gun with a tube of white painter's caulk. Painter's caulk can and should be used to perfect the edges of the ceiling. Cut the tip of the tube of caulk at an angle ¼-inch down from the end using a utility knife. This will give you a ¼-inch bead of caulk. Sometimes it is not possible to texture the very edges of the ceiling. Painter's caulk will hide edges that have not been textured, while also sealing the cracks or gaps that are present where the ceiling and the walls meet. To smooth the caulk, to push the caulk into the cracks and to remove excess caulk, run your fingertip along the bead and wipe the excess off on a rag. Allow the caulk, and the mud, 24 hours to dry before painting.

7. Use any color of paint to coat the mud. This should be done to prevent the mud from flaking, and to seal the surface of the ceiling. Use a roller and paint tray to cover the main surface area of the ceiling, and a small paintbrush or edger to do the edges. Painter's tape should be applied to the top edges of the wall again when you paint to protect the walls. Do not leave the painter's tape up that was applied the first time. You must remove the tape before you caulk or the caulk will be damaged when the tape is removed.
