My dad just bought a new home with 1400sqft metal building/shop. Before moving in we want to insulate it (probably open cell spray foam). The building is 15-20 years old R-panel with exposed screws and original paint. I assume the washers on the screws are no longer waterproof.
How would you waterproof/paint the building before insulation?
My roofer suggested an elastomeric (but didn't give me a specific one). SW and BM stores have elastomeric for masonry but no mention of metal.
Should I just caulk every screw/joint with NP1 and spray with SW Duration or Emerald?
thanks
