My dad has fabricated a hunting cabin using an existing metal building. The interior has been enclosed in plywood on ceilings and walls, insulated with roll-out insulation in between the metal walls and plywood. We used caulking and glue to seal in all the spaces and cracks. The building seems to be off-gassing, and it actually made him sick a few days after he stayed in it last year. I want to seal it before he comes back in November. I talked to an ecoadvisor, was recommended the HardSeal since we are not planning on painting, keeping the natural, rustic look. The cabin is 440 sq ft, how many gallons will I need to cover with one coat? I will need to coat the ceilings too, basically the whole interior. I plan on using a sprayer. SAMPLE - AFM SafeCoat, Hard Seal Wood Stains & Sealers

AFM SafeCoat HardSeal is our recommendation. It will cover about 350 SF per gallon. This is a two-coat process. You are welcome to try one gallon, but normally to encapsulate formaldehyde, two coats are required. You will need 3 gallons to cover properly.
