SPRAY GUNS

Reduce Pocketing in Studs

There are different ways to spray Open Cell foam to eliminate pocketing when spraying studs. Depending on the manufacturer you are using, they will recommend vertical or horizontal spray techniques – because of the chemical compound and how it settles in. For example; Rhino Linings recommends spraying horizontally with their Thermal Guard Open Cell. In doing so, I can improve my overall spray quality and deliver a better end-product.

Electrical Connections

Often overlooked when owning and operating spray foam equipment, is the electrical system.  When transporting to and from projects, the spray equipment takes its share of bumps and vibrations that can loosen electrical connections. I recommended rechecking all of the electrical connections at least once every three months. Weak connections can prematurely short circuit or shorten the life of the electrical components.

Use the Correct Mixing Chamber & PCT Combo

AP-EXWhen using the AP-EX extension gun in 16” on center stud wall type spray application – try using PMCs – 00X Mixing Chamber and PCT combination. (PN# KT-814-00X) Set your spray foam machine around 1,000 PSI on you’re A and B gauges. This will allow for further extended control of the AP-2s quick change mixing spray head.

Don’t run out of material in your transfer pump

When using your transfer pump a variety of issues can occur, the most common being running out of material. As soon as the pump runs out of material, it will cavitate from loss of fluid trying to pump air and most often run wild until the operator shuts it down. Having the pump run out of material can cause damage resulting in shut down repair time or even permanent damage to the pump, costing time and money to replace.  

Graco T3 Transfer Pump Packing

Graco T3 Retaining NutAs a general rule, the shaft area of your Graco T3 Pump should be checked, cleaned and lubricated every three to six months. When you get a new T3 Pump and during these checks, run about 20 gallons of material. Afterwards, tighten the packing nut by hand and then use the included spanner wrench to tighten an additional 1/8 to 1/4 turn.

Service Hoses

It’s important to service hoses at least once per year. Periodic inspections assure the integrity of the protective wrap by repairing worn areas. Small, but mighty, the protective wrap is vital in protecting the hoses and electric lines. So, when hoses are rubbed or worn thin, bursting can happen. Also, when electric lines are exposed, shock hazards and hot spots are a real concern – resulting in poor heating performance and leading to failure, damages, and injury.

It seems tedious, but proper inspection and service of the hose requires removal of all protective coverings, inspection of each material, electrical and air line for slices or areas which have worn or the hose has pulled apart at the jacketing. If you see any corrosion in the fittings, a simple acid wash and wiping off excess areas with steel wool, will help. Make sure you wipe clean then apply a light film of rust inhibitive paint. Inspect all electrical connections and exposed wires, then repair as necessary to test for continuity. It’s vital to make sure connections are properly sealed from weather.

Lastly, perform a 15 minute working pressure test (confirm test pressures for specific hose) and then rewrap the hose accordingly. It seems like a lot of steps, but trust me, you’ll be glad you did it!

How to Fix your Transfer Pump – Before you Replace it

PMC GHO, IPM OP series, Graco T2 Transfer Air motor performance

After use, the transfer pump air motor starts operating sluggish and leaks air. This is generally due to deforming (wear) of the upper reversing spring and the upper air valve gasket. You can notice the spring wear off in two ways. The first being the pump fails to return to the down stroke and secondly the pump will pause momentarily when reversing to the down stroke which appears as a cavitation type action. In this situation, hanging the spring is the best solution, but when in a pinch, stretching the spring to its near original length can get you through the day.

Test Your Side Seals and O-Rings for Proper Seating

After replacing the o-rings in your AP-2 Gun, it’s important to make sure they are sealing properly. In order to test if the side seals are seating properly and the o-ring is sealing, follow these steps:

With the safety on and the gun disconnected from the hose, hook an air hose onto the gun and pull on the trigger. This pulls the chamber back slightly which cuts the airflow coming out of the tip. The air should cease from blowing out of the tip and should only slightly exhaust at the vent near the handle and the air-motor. If the side seal, the o-ring around the side seal or the oring at the screen screw is not sealing the air will push out of the check valve seat.
