In this episode of Fix-It Friday, we teach you how to identify and fix issues with your spray foam hose heating system using a PMC PK-25 spray foam machine. Hose heat is the biggest technical support issue we get and there are a few common issues that can be easily identified and resolved while on the job site.Continue reading

Having Quality Equipment
When starting your own spray foam company, it is important to have high quality equipment from reputable manufacturers. Companies like PMC and Graco have products that are quality tested and built to last. By spending more money on quality equipment now or buying new instead of used, you can save on having to replace less quality products more frequently. Oftentimes, used equipment is less costly than new because all the parts are brand new.
Using New Spray Foam Material
When using new material, always check the manufacturer’s SDS for recommendations on spraying. Every material sprays differently in different environments and by following recommendations provided, you will be able to spend less time making adjustments and increase material yield.
When to Perform Maintenance Checks
Avoid unnecessary down time by performing maintenance checks before you start your day. It is easier to perform these checks while the system is cool and pressure free. Taking this step saves you downtime later if something was wrong.
Keep Your Material Warm
Having warm material is very important for spray foaming, however, it is easy to think a few degrees won’t make a difference. It is important for the health of your equipment and the quality of your work to wait for those few extra degrees to get you the best quality!
Remember to always warm up material to the manufacturers recommended temperature to get the best spray!
Daily Hose Maintenance
Daily hose maintenance is important to prevent your hoses form getting unnecessary damage and ensuring your hose and equipment last longer.

Changing material from Open Cell to Closed Cell or vice versa can result in many issues with product loss, cross contamination or time loss. By using the Logan Manifold you are able to quickly and efficiently change from one material type to the next without wasting extra time or material.
Spray Foam Equipment Thermal Expansion Hazard
Fluids subjected to heat in confined spaces, including hoses, can create a rapid rise in pressure due to the thermal expansion. Over-pressurization can result in equipment rupture and serious injury.
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.
