Plain, flat drywall requires on an artistic look when cosmetic patterns are implemented. Texture can also hide imperfections like screw holes, visible seam tape and uneven joints. Walls with texture or patterns are more difficult to paint than flat walls. Regular paint roller covers can leave spaces unpainted, so use a thick, long-nap roller created particularly for textured walls. Washing textured walls is every bit as catchy, so dust them often to help prevent buildup.
Clean out the wall, unless it is new, unpainted drywall. Use a ladder to get to the high locations, and clean it from top to bottom with a soft sponge and residue-free cleaner. Dry the entire surface with clean towels.
Sand a shiny, painted wall lightly with fine sandpaper, or employing a rotary or oscillating tool with a fine-grit sanding accessory. Rough surfaces hold joint compound better than shiny ones. If the paint is flat, there is no requirement to sand. Wipe excess sanding dust with a rag.
Transfer half the joint compound in the full container to a empty bucket using a small trowel. Place the lid back to the container to maintain the material from drying out.
Attach a long paint mixing instrument into a power drill. Push the end of the device into the open bucket under the surface, but not into the base. Turn the drill on it smallest setting. Push the instrument deeper in the bucket and boost the rate of the drill as the material softens.
Switch off the drill. Add 1/2 cup of water into the bucket. According to Tim Carter of Ask the Builder, pre-mixed joint compound should be smooth, so water has been inserted to soften it. Turn the drill back and combine the water into the joint compound until it is smooth, without any lumps. The consistency should not be runny; just softer than the original mix. Switch off the drill, and disconnect the instrument. Harness the instrument against the face of the bucket to remove excess material.
Fill a joint compound tray with the mixed material. Twist it out and use it into the wall using a drywall mud knife, which looks like a wide putty knife. The layer should be approximately 1/2 inch thick. Refill the tray and use more substance into the wall until the wall has been coated, or until you run out of material.
Attach a cigar with a clean roller cover into an extension rod. Roll the instrument from the cover of the wall into the bottom, as though you were painting it. Use a light touch, as pressing too difficult can remove the material. Roll in long, overlapping motions to create a much, stippled texture within the wall.
Create additional finishes and patterns with special tools or normal household items. By way of instance, drag a notched trowel through the joint compound on the wall to make ridges. Or, press a stiff stippling brush into the moist material and turn it to create swirls. Instead, press cookie cutters against the surface to create layouts, such as circles or stars.
