3 1/2" Foam Roof
Working on a 3 1/2" SPF Roof. Any secrets to keeping the surface smooth at that thickness?How many lifts do you guys normally do to get this thickness? |

Hi Bayouboy, There are different ways to get a smooth profile at greater thickness. Typically we put down 1"1/2 per pass. The 1/2 lap method is used to spray at greater thickness. Have a look at our projects at sprayfoamservices.com to see the 1/2 lap application. Give me a call to discuss your application options to installing this method.

HI Dave Thanks, I went to the site and took a look at the 1/2 Overlap. To get the 1 1/2" per pass, are you doing it by 2 each 3/4" lift, but using the 1/2 overlap? Or, are you putting down 1 1/2" at a time. I have always been afraid of two thick of passes because it always takes to long for the lift to harden up enough to walk on. I am going to give you a call this morning to discuss! Thanks Steve |

Hi Steve, we are putting down 1"1/2 at a time. You will find that the foam will harden just as fast as other ways. You will also get a stronger bond in the pass lines. Looking foarward to your call. |
