[This training material is not a substitute for reading and understanding all instruction manuals and warning labels supplied with the equipment, nor it is a substitute for reading and understanding the Safety Data Sheet (SDS) supplied by the material supplier.] [GRACO] [MAGNUM TRUE AIRLESS HOW TO SPRAY] In a good spray pattern,
the paint or material sprayed is completely and evenly distributed
onto the surface. In this video, we’ll cover several techniques
you can use to ensure a quality finish. In this section, we will discuss: [Spray Patterns]
spray patterns, [Spray Techniques]
spray techniques. [SPRAY PATTERNS]
Before starting your project, if you don’t have a lot of experience with spraying, use some scraps of cardboard
to test the quality of the spray pattern. You could spray a large flat area
like the side of a house that’s not easily seen or you could practice with water. Just make sure you let the surface dry completely
before applying your paint. As you’re practicing,
start at the minimum spray pressure and slowly increase the pressure
until a good spray pattern is achieved. This is a good spray pattern. Notice that there are no runs in the pattern
and that the pattern itself is smooth and even. If you pattern has what are known
as fingers or tails and uneven finish such as this, then the pressure should be increased. Spraying at the lowest pressure possible,
while still getting a good spray pattern will save wear and tear on your pump
and spray tip and reduce over-spray. If you’re at the maximum pressure setting
and the spray pattern is still not suitable, a smaller tip hole size should be used
or your material may need to be thinned. Follow the instructions on the back
of your material container under spraying applications. [SPRAY PATTERNS] [12 inches]
The gun should be held approximately
12 inches from the surface and aimed straight at the surface. While moving vertically or horizontally, the gun should remain
at a consistent distance from the surface. [UNEVEN]
Fanning the gun to direct the spray at an angle, causes an uneven finish. [EVEN]
Flex your wrist at the beginning
and end of each stroke to maintain an even coat. Don’t spray at an angle. Keep the gun perpendicular to the surface. [Proper Gun Positioning]
To practice proper gun positioning
without spraying, try moving the gun
and holding it perpendicular to the surface [2 inches]
only about 2 inches from the wall. Notice how at the beginning
and at the end of each stroke you’ll flex your wrist
to keep the gun square to the surface. [12 inches]
Move out to 12 inches for additional practice. Work in sections only
as far as you can comfortably reach. First, spray the outer edges
and cut in any corners. [OVERLAP BY 50%]
Then, aim the gun at the edge
of the previous spray pass so the spray pattern is actually
overlapping each pass by one half. Trigger the gun after starting each spray pass
and release before ending the spray pass. Your arm should be moving
when the trigger is pulled and released. This will create a nice fuzzy edge
around the entire spray pattern so your next pass will blend
into the previous pass. Rotating the guard changes the pattern to either vertical or horizontal orientations. When spraying on broad, open surfaces
such as ceilings and bare walls the outside edges should be sprayed first. Then the middle can be sprayed
more quickly. For vertical corners,
turn your guard so the spray tip is on the top and aim your gun into the corner. Spray along the corner applying an even
amount of material along both sides. Typically, when painting, it’s best to start at the top
and work your way down. Begin by spraying any eves
or the underside of overhang. The direction you spray
is determined by the construction. As a general rule,
spray horizontal and make sure you direct the spray up a little
to spray the bottom lip of your siding. With a little practice, this easy to use sprayer
will have you spraying like a pro in no time. Remember, point the gun straight at the wall
without tilting up or down or angling left or right. Start moving the gun before and after
you trigger. Move at a consistent speed
and when spraying, overlap the prior spray pass by 50% Allow enough tome for paint to dry
before removing tape from your trim. This will result in crisp, clean lines. [GRACO PROVEN QUALITY. LEADING TECHNOLOGY.]

  3. The soffit vent should have been masked off. After a few coats of paint, those small vents can become nearly clogged shut ruining the efficiency of the attic ventilation.
