sanity check - closed foam for enclosed trailer
I Have a 24' enclosed car trailer (8' wide and 7' tall walls). I have completely striped the entire inside walls & ceiling (just bare studs). Located in TX.
With me bringing my trailer to the sprayer and doing any required clean-up/scraping, etc...
Can anyone tell me what is a fair price (or range of prices) for spraying closed cell (Demilec Heatloc Soy) with 1" on walls and 2" on the ceiling (nothing on floor)?

Greatly appreciate any feedback!

Thank you. Very helpful.

Anyone have thoughts on spraying the underside of the floor? Worth it?

I sure would spray the underside of the floor, we are putting a heated floor in our new spray foam trailer and our old trailer floor is insulated as well as the walls and ceiling.There is just as much heat loss out the floor as the roof of the trailer because it is the same square footage, but the ¾ plywood is about R-2.

Around a dollar per board foot on a small job plus prep and cleanup.

Good deal. I'll plan on the floor as well.

Another question I thought of... The roof is (thin) galvanized steel and walls are aluminum. Should I wiped these down to clean any oil, etc? Maybe with naptha or acetone?

With especially the roof, it's so thin and flexible, I want to make sure it sticks well and isn't able to shake itself off.

Thanks again all for the help.

I've seen really poor adhesion on some cube van roofs before, I would prep it with some degreaser if it was my trailer.

What's the best way to clean/degrease?

I like to wipe down metal projects with denatured alcohol and clean white cloth towels, like t-shirt cloth. The denatured alcohol seems to do a nice job, and evaporates quickly, and the odor is tolerable. Of course, there are hundreds of products available, but try that. Get a gallon or two at a box store.
