I had to repair the kitchen walls to get ready for the cabinets. I started by patching the holes in the walls There was one big patch and several smaller ones. I managed to get all the material I needed out of one piece of dry wall. Then I plastered, starting with the seams, and working outward from there. I used curing plaster instead of drywall mud. This allowed me to fill bigger voids and gave me a harder surface in the end. I smoothed over the texture on the entire two walls. Last was painting. I used a roller with a very short nap for a smooth finish.
