Make sure to have tape, a masking gun, and masking paper. You'll also need an extra roll of tape for your other wrist/hand to tack on the paper. Rip the paper before climbing the ladder as long as possible. Use as few sheets to go faster. Only use a masking gun for soffits and brick / areas that need paper. Refer to the window video for how to effectively mask windows. Remember that all areas need to be masked before spraying.
