Before insulating the walls and ceiling, you must prep the walls and ceiling.

There were many steps to spray foam prep, spread over a few days of work.

1. Making sure there no leaks anywhere, including around old rivet holes (covered in FlexSeal)

2. Taking out anything that might get covered in the spray foam

(such as our front flashers - thank you Corinne and Delaney for the help!

3. Installing anything external that needed to be bolted or wired internally

Lights, MaxFan, rack for the rooftop deck, solar panel rack, framing out the walls and ceiling, wiring all external lights and replacing bulbs

4. Thoroughly cover anything you don't want covered in spray foam

Then you're ready for the spray foam. Whether you're doing this next part yourself or getting a professional to do it, the preparation is still super important.
