if only it were that simple...well then everyone would be doing it.
if your client doesn't mind tacking on an additional $50,000-$ 70,000.
If you think you can go out and buy a rig and start spraying foam...you will be in for a long and tough road. The demand for the product is there, but take your time and do your research. The equipment is extreemly tempermental. The "proportioning machine" used to pump, heat and mix the chemicals is extreemly complex with many, many, many hydrolic, electical and heating elements. This machine w/ necessary heated hose (approx. 250') alone is about $26,000 for a good set up. (The hoses can run from $1000 to $2000 per 50'). Toss in a 40 kw generator at $13-14000, an 71/2 horsepower air compressor w/ air dryer @ $3,500, gun to spray with @ $1,700 (u really should have two), electrical breaker box and wiring @ about $2500, top it all off with a 20' trailer to haul it in @ $10,000 and you have yourself a nice rig to spray with. Now you need a heavy duty pickup truck to haul the trailer, F-350 used @ $20,000 should suffice. Oh ya...did i forget to mention that someone need to build it for you if you don't feel like it...add $2,500-$5,000.
You now have a rig ready to spray foam...problem is...u dont know how. And if you think pulling the trigger is the simple answer, you are saddly mistaken. You are using a plural componant machine. This means you are taken two different chemicals, heating them to very specific temperatures, keeping them at that temperatures in the hose, then mixing them in the gun and spraying them onto the surface to be insulated. So many things can go wrong. If for some unknow reason, one side of the machine drops in pressure, and it happens, then this causes a crossover of chemicals which causes a mixing of them where it is not supposed to mix...in the hose...resulting in foam in your hose...if it only made it 50' or less...it only cost you $1000 to $2000 dollars to replace that hose. Not to mention you now have to disassemble your gun and all its million parts, and clean it by hand. And that is only one undesirable scenario. Getting the picture yet?
I have spent the last 6 months researching this exact topic. I am in the process of not only buying the equipment, but joining a sprayfoam dealership as well. I have been to two training seminars, polyurea applicators and gusmer's sprayfoam mechanics class. I have spent over $5,000 on these two training seminars and it was worth every penny. I will be attending a third training seminar that will last 4 days for bidding and sprayfoam application. This one will cost me nothing, unless you are counting the $15,000 it will cost me to join the dealership. Take my advice...if you are serious about this, and you have the cash or good credit to get into it, research it...u can start here:
