Material Spraying Issues
It’s less common when material will not spray on the ‘A’ side and ‘B’ side at the same time, but when it happens, there could be a number of factors at play. If you find yourself in this position, take a look at these common reasons;
- Proper operation of the pumping system. (execute initial startup checks)
- The product cold, it doesn’t flow properly.
- Failing delivery supply like transfer pump wear or neglect.
- Your regulator could be malfunctioning; Are you getting enough air supply to your Transfer Pump?
- Failing packings from wear or neglect.
- Clogged screens can also cause major issues in proper flow.
- Recent crossover in hose or contamination within the gun itself.

The Magnificent Membrane
The manufacturing and installation of low slope- polyurethane foam membranes (LS-SPF) takes place simultaneously, resulting in an emphasis is on manufacturing and processing controls. LS-SPF systems are formed by the resulting reaction created between mixing two liquid chemical components “A” and “B” while spraying to a prescribed substrate. The two liquids are packaged in individual containers, usually 55 gallon drums. The set, containing 500 lbs of Resin-“B” component and 500 to 550 lbs. Iso-“A” – are sold by the pound. They are processed in a 1:1 mix ratio or mixed equally in parts by means of plural component airless spray. Similar to airless spray painting and coating applications, the two materials are kept separate just prior to spray applying to the prepared surface. From the drums, the two liquid components are displaced or transferred equally from their individual containers to a processing machine called a proportioning unit for its ability to place both products under relatively equal pressure (proportioned equally). The proportioning unit is equipped with individual pumps and heaters that places the components under “prescribed” relatively equal, pressure (1000-2000 psi) and heat (110 to 160 degrees f).
How to clean a spray gun?
Considering the abusive nature of using grinders and wire brushes to clean parts – oftentimes this causes premature wearing of parts by cleaning them alone. Therefore, I recommend using a good quality gun cleaner and utilizing a heated parts soaker or even a non-heated soaking pot to clean parts. Be sure to reference the manufacturer for proper soaking times.

Pre-greasing Gun Parts
Most new-age spray guns are equipped with a grease fitting to lubricate the gun after service. However, pre-greasing each and every par,t within the wet end of the spray gun during assembly, assures each part is properly greased – without relying solely on the zurk fitting.
