Remove dust and loose material, but don’t remove all of old plaster. Just make sure the old plaster is smooth. When the walls are ready, spray them with clean water using a spray attachment on a hose. Don’t overspray as this will cause puddles and runs.

Step Two – Mix the putty

Step Three –Spray the putty
Opereate the airless paint spraying machine according the manual. And hold the spray gun about ten inches from the wall. Keep the nozzle pointed directly at the wall. Move the spray gun about three feet across the wall in a horizontal direction. Putty from the top of the wall to the bottom of the wall. Overlap the sections as you work.
