Bedroom Closet Patching

After all of the demo and mudding, it takes about 12-18 hours for the mud to dry. The dry time depends on thickness. After it drys, I sand it down tediously until it seems mostly level with the wall. The sanding produces a lot of dust, so it's important to wear something over your mouth and nose. Can't do much about the layer of dust on the arms though. Then I rinse and repeat, filling in the holes and cracks with more mud in order to sand again. I did this for 3 days before completing the drywall and being able to paint. The bottom right image shows the closet after the whole wall patching process is complete.
