The quick answer for a fresh hand to the airless paint spraying system

What four basic components does virtually every coating contain?

• Binder, Pigment, Solvent, Additives

What determines a fluids flow rate in an airless spray system?

• Tip orifice size and pressure

What are three major advantages of using an airless sprayer?

• Speed, Quality, Versatility

How are airless sprayers rated by equipment manufacturers?

• Maximum tip size, Gallons per minute, Maximum pressure in psi,

Horse Power

What are the four major components of every airless sprayer?

• Motor and Drive System, Pump, Pressure Control, Spray Gun/Tip

Explain how the last three numbers of a spray tip tell you the orifice size

and spray pattern fan width.

• First digit when doubled is the fan width in inches
• Last two digits are the orifice size in thousandths of an inch

Why do spray tips wear and how does that affect your production and

job costs?

• Coatings have abrasive materials in them and wear tips under

high pressure

• A worn tip reduces the fan width and increases fluid flow, increasing

labor and paint costs

Why is the 50% overlap method the best way to get an even quality

spray finish?

• Spray tips are designed for a 50% overlap so you get a smooth even

finish with no visible lines

What are two spray technique mistakes many new contractors make?

• Spraying at too high of a pressure
• Not triggering the gun properly at the start and stop of each stroke
