Properly Trained Team

Taking time to properly train your team will prevent losses in both time and money. By investing in your employees, you are able to have them run more efficiently and spend less time fixing costly mistakes.

Training doesn’t always have to take a ton of time out of your schedule. Taking one day to train a group of employees on proper equipment handling, maintenance or basic trouble shooting can prevent hours of lost time. Afterall, spending a few hours to train your crew on taking care of equipment can prevent having hours or even days of downtime due to a preventable mistake.

Ventilation at the Job Site

It may seem redundant but, when spray foaming, keep your job site ventilated and do it every single time you spray. Keeping the work area ventilated will prevent unnecessary exposure to fumes and particles that can cause damage to workers. Best practice is to be aware of the airflow and have a source of entry and a way for air to flow out of the work space. Also remember to keep the area ventilated until the re-entry time specified by the foam manufacturer.  

For more information on proper ventilation procedures review the EPA Spray Foam Ventilation Guidelines 

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.

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;

  1. Proper operation of the pumping system. (execute initial startup checks)
  2. The product cold, it doesn’t flow properly.
  3. Failing delivery supply like transfer pump wear or neglect.
  4. Your regulator could be malfunctioning; Are you getting enough air supply to your Transfer Pump?
  5. Failing packings from wear or neglect.
  6. Clogged screens can also cause major issues in proper flow.
  7. Recent crossover in hose or contamination within the gun itself.

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.

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.

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.
