How to Maintain Used Spray Foam Insulation Equipment

By Kevin Malone

Working with spray foam requires specialized equipment that usually come at a premium. For businesses or contractors working with a tight budget, buying new equipment may not be a viable option. This is why at Intech Equipment & Supply, we offer used trucks and equipment as affordable alternatives.

Overall, you should care for your used spray foam insulation equipment just as you would for your new equipment. Regular checks, daily cleaning, and proper storage are key to extending the life of your guns, proportioners, and other accessories. By following the manufacturer recommendations, you can use everything for their longest possible lifespan.

Caring for Your UsedProportioner

Machines that are made well, like those from trusted brands like Graco and PMC, can last for years and therefore have multiple owners. After our sales team matches you with some quality used spray foam machines, they need to be maintained just like a new machine. Follow the same daily guidelines as you would follow for any machine and you'll keep it running for as long as possible.

  • Checkthe pumps and Y-strainer periodically for large particles. As the y-strainer prevents large pieces ofcrystallized materials from entering the machine, it will get clogged. Too muchblockage will decrease your machine's performance and affect the quality ofyour spray foam application.
  • Checkits power source with an amp clamp to make sure that the incoming voltage issteady and at the same level that the manufacturer recommends.
  • Youshould also be sure to keep the drum mixer free from buildup. As you apply yourmaterials, the drum empties and lets in humid air, which will crystallize thematerials within. Any buildup causes material feed problems and affects thelongevity of your proportioner.

Caring for Your UsedSpray Foam Guns

We continually update our inventory of quality used spray foam guns, so check often to find out what's new in our store. Caring for a used spray foam gun is much like maintaining a new one. You must keep it clean and free of clogs so that it continues to work properly.

  • Runonly one gun off a single proportioner. By trying to 'multitask' andattach more than one gun to a machine, the pressure and flow for each gun won'tbe even. This can cause a variety of maintenance issues that lead to cloggingor inconsistent application results.
  • Keepit as clean as possible! Spray foam guns take the brunt of the action and needto be properly cleaned, lubricated, and stored after each use. Though it mayseem tedious to flush out the mix chamber or apply WD-40 to specific parts,you're investing in its longevity. Used guns may already have a few years undertheir belt, so it's even more important to stretch them to their maximumlifetime.
  • Ifyou find that your used gun is clogging once a week, you should strip it downand clean all its parts. Soak individual parts in a solvent to removedebris. 
  • Ifyour air purge gun uses the spool valve method, you should check the o-ringsand replaced any that are damaged.
