mason Posted: Mar 11, 2010 12:14 PM	This is one of those things that you want to be smart about. Do not spray on wet wood. Make sure the moisture content is below 19% as measure with a moisture meter like a Delmhorst. It may vary in some places so be sure to check all of the nooks and crannies as well as the middle of a bay. Any recommendations from your supplier in regards to the project that are outside of typical industry best practices or their written specifications should be in writing to protect you if something hits the fan later.

Fresh lumber will probably shrink as it ages and thouroughly dries. If you go back to the job some time later because it appears the foam shrunk and made some small gaps between the rafter and foam, you will have proof that it was not the foam that shrunk but the wood.
