As with most plastering jobs, the cost to skim a large wall will depend on its size and how much preparation work is needed. You can cut down on some of the preparation costs by making sure that furniture is moved out and areas near the wall to be worked on are covered with dust sheets. Your plastering professional will prepare the wall, fill any cracks and then smooth the plaster on to the wall, skimming over what is already there. This thin coat of plaster will seal the wall and provide a seamless finish that can be painted over or wallpapered as you desire.
