Posted: Mar 22, 2009 05:40 PM	01, 02, 03, 04, 05 To the guys spraying with the larger machines. Other than the amount of material that you are putting down, do you guys see a difference in spraying with an 01 chamber all the way to a larger chamber on a roofing application. Is there any difference spraying with an 01 chamber to an 03 chamber other than having to move a little quicker? I should have my 250 in by the end of the week and am anxious to see the difference that it will make from my E-20
clint moore Posted: Mar 27, 2009 11:34 AM	The reactor E-20 can sray up to a 02 chamber,anything bigger the output of the chamber will out run the machine. I beleive same goes for the G250 unit. Guys with bigger machines doing roofing use bigger chambers to get a higher coverage rate. Time is money...

Dennis Davidson Posted: Apr 01, 2009 11:33 AM	Your G-250 will run circles around the E-20. What gun are you using? We normally spray with our G-250 using the 03 and the Gama "Master" gun. The size of the spray tip doesn't make you a better applicator. More is not always better! There's a lot of "tricks of the trade" to enable most applicators to make a good roof using any size mixing chamber. Quality of the product should ALWAYS be first. The quantity will follow.
Posted: Apr 01, 2009 04:29 PM	Hi Macs I am using a Fusion AP with both and 01 and 02 chamber. Don't get me wrong, we are not bumbling idiots on a roof, but on the other hand I can't spray a perfectly smooth one like Bayer did. Even the roof on the Superdome has bumps on it that you can visible see; however, I understand that it was sprayed in probably one of the harshest enviroments around hanging from a harness on a 25-30 Degree Angle.

Dennis Davidson Posted: Apr 01, 2009 10:42 PM	Steve My comments were not all directed to you. I can tell that your doing good work. Does your Fusion gun have a small pattern? What I mean is do you have to hold the gun up above your waist or spray a few feet in front of you to get a descent size spray pattern. If so, ask your supplier for a wide tip. I think it's called a WA-02 or 03. (WA - wide angle). It's not well known that these tip even exist. I just recently found out about it myself.
Posted: Apr 02, 2009 12:48 PM	Hi MACS I didn't take it like you were directing at me. I was just trying to convey that I am not a beginner by any means and definately not as good as the Bayer roof. I am slightly ahead of the middle of the pack and always willing to learn.

To the guys spraying with the larger machines.

Other than the amount of material that you are putting down, do you guys see a difference in spraying with an 01 chamber all the way to a larger chamber on a roofing application.

Is there any difference spraying with an 01 chamber to an 03 chamber other than having to move a little quicker?
