Basic Spraying Techniques

NOTE: Use a piece of scrap cardboard to practice these basic spraying techniques before you begin spraying the surface. Anything you don’t want painted that is in 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 angle causes an uneven finish.

NOTE: How fast you move the sprayer will affect spray application. If material is pulsating, you are moving too fast. If material drips, you are moving too slow. See Trouble- shooting, page 18.
