SPRAY GUNS

Spray Gun Safety

Every gun has a safety feature. You should get in the habit of turning on the safety feature whenever you stop spraying – whether it’s to talk to someone or check your depth. It’s an often overlooked step when a new applicator is learning, but can quickly cause serious injury or damage if the spray gun releases unmanaged chemical.

Proper hose care

When heating up your hose, I highly recommend unravelling the bulk of it. There are two reasons why.

One – the hose will create hot spots and could potentially get to the point where the hose would melt and burst open after an extended period of time. The second reason – as you spray material, you’ll get inconsistent heat and as your material cures, your application will become poor and inconsistent.

Best Tool to Have

As Spray Foam Technicians, we recommend one tool you should have on hand that can keep you and your crew up and running. When you suspect that you may have an electrical issue and need to contact a tech for help, one of the first things you may be asked is to confirm voltage’s through the spray system. Having a Multi-Meter on hand in your spray rig will help you to easily determine the answers you need to get your system up and running asap.

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

PMC AP-EX Spray GunWhen using the AP-2 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.

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.

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.
