Daniel Rose Posted: Nov 29, 2006 09:10 AM	Calculating usage / cost of material We pay for material by the pound , but our guys track what they are using by the gallon. We guess that there is about 50 gallons of A and 50 gallons of B. I then divide by price for each barrel by 50 to get a cost per gallon. I figure 1/2 gallon of A and 1/2 gallon of B to get one gallon of finished material. I think this works out right, but would love to know if anyone has a better way of finding cost per gallon. By the way this is closed cell. I don,t know if that matters.

Brian Mulder Posted: Nov 29, 2006 10:05 PM	Are you doing the work on a time and material basis if you are figuring what you have already used vs. what you need to cover at a certain thickness? What about figuering the square feet you are spraying? For example 100 sf at 1 inch thick= 100 bd feet. 100 sf at 2 inches thick = 200 bd ft and so on. AT this time of the year in central New York State I average 5000 bd ft per set as told to me by my foam supplier. (closed cell). Of course I am still new to this, just finished my first job, and will keep tracking it. B

If you figure 100 gallons per set, that is 2,380 strokes per set. Most 2lb foams get 4,000 bd ft per set. I figure and bid the jobs by the board foot, then by checking the number of strokes, calculate the amount of material used and make sure that I bid correctly and verify yeild. Hope this helps you, but I think I confused myself? George
