NOTE: Use a piece of scrap cardboard to practice these
basic spraying techniques before you begin spraying the

the area of your spraying surface should be covered
or removed.
Hold sprayer at least 25 cm (10 in.) from surface and
adjust accordingly to achieve desired results. Aim
sprayer straight at surface. Tilting sprayer to direct spray
