I'm working on drying out some walls and ceilings which had spray foam used as an insulator. It's pretty much glued to the joists and studs, so there's no air flow along the sides.

Client has agreed to cutting out the spray foam in the ceiling (good, cause there's lots of mold up there behind the spray foam), but not the walls. I can ventilate the space behind the studs by drilling holes in the walls.

I've tried tenting the room, but it only shaves a couple of days off the drying time. Currently averaging 14-20 days for drying time, and I'm hoping for a 7-day turnaround.

The current room is 40x10x10, and the next three will be 20x10x10. Structure is pressure-treated lumber (2x4 and 2x10). Flooring is pressure treated plywood.

I currently have access to 4x LGR 2000 dehumidifiers, 2 axial fans, 1 vortex axial fan, and as many heaters as I can find plugs for.

Overall though, these rooms are taking a phenomenally long time to dry out, and I'm hoping someone might be able to throw me some ideas.

Thanks

Tom

I am sharing my personal experience, I used spray foaming process as an insulation in my bedroom’s wall. And a small leak might only take a day or two to dry. But a larger leak could take nearly a week. Completely submerged foam could take longer. It all comes down to the amount of water in the foam.
