Tape around windows, light fixtures, baseboards or anywhere else you don't want the texture spray.
In a five gallon bucket, mix about half of a 50-pound bag of drywall texture powder according to the manufacturer's instructions. Using a half inch drill with a paddle bit, stir the mixture until all the lumps are out and the mix has a consistency similar to that of sour cream.
Before you try a test spray, prime the spray gun to make sure the mixture is coming out consistently through the hose.
Next, try a test spray. With a sweeping motion, stand about four feet away and spray the mix on a piece of wallboard. Repeat until you feel comfortable with the results.
