Airless Sprayers

Consistent Results - Always!

An airless sprayer is the most efficient way to apply roof coatings. Airless sprayers use a hydraulic pump to atomize the coating. Elastomeric coatings require higher pressures and flow rates than paints. A roof rig usually has a minimum pressure of 3000 psi with a flow rate of of 3 - 4 gallons per minute.

A siphon hose on the material inlet typically is used to draw material directly from 5-gallon pails or 55-gallon drums.

A spray gun with an extender wand allows for comfortable coating application without having to hold the spray gun uncomfortably close to the surface. A .017 tip is usually recommended for roof primers and .031 for elastomeric coatings. Tips are reversible for easy cleaning and clearing of occasional tip clogs.

Proper spray technique involves keeping a gun level with a roof's surface at all times, maintaining a consistent distance between the spray tip and surface. Use a overlapping, crosshatch pattern to ensure complete coverage and a uniform finish.

Preventing Overspray

If overspray is a concern, consider using coating spreaders instead. Depending on your roof configuration, spreaders may be faster and easier to use. Spreaders can apply a consistent 20 wet mils in one pass with application speeds up to 300 linear feet per minute.
