[RE-wrenches] Icynene spray foam insulation patching

[Luke Christy]

It would be interesting to know what this contractor was referring to specifically. I've used Great Stuff extensively in buildings insulated with 1/2 lb polyurethane foam and haven't noticed any obvious adherence or other compatibility issues. I believe Icynene is usually a more dense 2 lb product. I wonder if there is some kind of chemical incompatibility. Anyone else know about this?
