Q: Does the PUP come with a warranty?

A: Yes, The PUP comes with a one year manufactures warranty.

Q: Does the PUP need a special foam formulation?
A: No, the PUP has been designed to process the same foam used by high pressure machines. The PUP sprays both open and closed cell foams as well as many polyurethane/polyurea coatings

Q: How does it work? I've been told the foam must be sprayed at high pressure(1,000 PSI) and 110-120 degrees
A: The LIL PUP spray gun is unique. It features an air nucleation gun which injects compressed air into the liquid components prior to exiting the gun. The liquids are frothed making them mix easier and the air acts as a propellant to expel the mixed foam. The air nucleation allows the foam to be processed at much lower pressure(200-600 PSI) with temperature as low as 60 degrees F

Q:Where can I buy the foam?
A: Contact Dan for recommended suppliers. We work with several that will sell you direct, no certification is required. There are online certification programs too!

Q:How much hose does the PUP come with?
A: The PUP comes with 50 foot insulated, heated hose wrapped in a scuff resistant jacket. A 50 foot heated extension hose can be ordered to reach 100 foot. 150 foot is the maximum hose length

Q: How do I flush out the machine after use?
A: The PUP should be flushed with a pump lubricant(Plasticizer) for long term storage. It is not necessary to flush each day and chemical can be left in the lines for up to week. Contact Dan for more details.

Q:What is included with the machine?
A: The PUP comes with the proportioning unit, 50 foot heated hose, gun, reusable spray tips, ratio tip, night cap, flush pump, drum feed hoses and all necessary fittings to attach to drums. The operators guide has easy to follow step by step directions. My personal cell phone number is on the sticker affixed to each machine. Feel free to contact me with any questions. I must be crazy to do this, but I stand behind all the machines I build- Dan McDonough (909) 841-4236

Q: What else do I need to buy to use the PUP?
A: You will need two drum cradles, fresh air system, personal protective gear, cleaning solvent, an air compressor rated for minimum 12 CFM@90 PSI, and of course the spray foam

Q:Does the foam have the same yield and insulation values compared with high pressure machines?
A: Yes, the finished product has similar properties and you can expect professional results. Substrate and foam temperatures will impact yield as well as thickness applied.

Q:How much foam can you spray in one day with the PUP?
A: Customers average about 1,000 pounds per day or about 4,400 board feet when spraying closed cell foam.  Some spray as much as 2,000 pounds daily.

Q: I have heard of some foams having a fishy odor after being applied, what causes this?
A: The fishy odor is usually foam that has been sprayed off ratio and poly rich(too much B component). The PUP comes with a ratio tip for checking ratio at the gun, not available on high pressure models. High pressure machines have impingement mix guns with very tiny orifice mix chambers. These are between .020 and .040" or 20 to 40, 000th of an inch and have very small filter screens that are prone to plugging. The ISO(A component) can crystallize  and these crystals will often plug the gun filters causing an off ratio condition. The PUP has larger 1/8" ports and is less prone to plugging. We also have independent pump speed controls, so you can adjust each pump output to achieve correct ratio.

Q: Can you spray on metal and wood substrates?
A: Yes, the substrate must be clean and dry. Spraying on cold surfaces will reduce the yield and slow the reaction. This is true with high pressure machines also. Cold metal is a major heat sync and metal should be warm prior to application for best results

Q: Do you have any used or rental equipment?
A: We do not rent the machines. We get this question all the time. You may consider buying the PUP's and starting your own rental program! 

Q: What is the lead time to get a machine?
A: The lead time varies and orders are assembled in the order they are received. Usually 2 to 3 weeks depending on production 

Q: Can you spray foam roofs with the PUP?
A: Yes, the PUP sprays the class 2 roofing foam equally well. Note: Class 1 foam is needed for interior applications. Roofing foams are 2.5 to 3 LB density and higher compressive strength compared to wall foams. Dan sprayed foam roofs for 5 years back in the 80's and will help you source all the products you'll need including the coatings.

Q: Are there any options available for the PUP?
A: Yes, we can add material tanks, heat exchangers, digital RPM meters, flow meters, larger output pumps etc.

Q: How much power does the PUP require?
A: The PUP operates on 15 amps@ 115 VAC power. Compare that to 50-120 amps 230 VAC for high pressure models!

Q: How is the PUP shipped?
A: The PUP is shipped from Cottage Grove, OR in a sturdy box via truck. 

Q: It's cold here in the winter. Do we need to heat the foam?
A: Yes, we recommend heating the drums to 80 degrees F for optimum performance. The best method is to build a hot box that covers the drums using 2" urethane board stock insulation and place a small space heater inside.  Band style drum heaters are also good for warming the chemicals. 

Q: How do I trim the foam?
A: Several products are available including saws, foam planes, and attachments for grinders. One added benefit with the PUP is the tight spray pattern which makes it easier to control the thickness applied. With a little practice you will be able to avoid most trimming!
