Foaming ceiling

[skip hartline]

Afternoon all,
I got the old ceiling out and the foam looks better than I thought it would, no bare spots but the foam ranges from 1/4 inch thick to the full depth.
short of scraping it all out and gluing in foam board does any one have ideals how to foam overhead on the thin spot and not make a mess. Thanks for
any ideal or experiences.

Don't scrape. Just fill the spots with suitable spray foam.

There are companies that do that. You will need to mask EVERYTHING because where ever the foam goes it does not come off. I had it done so it was
over full and then smoothed it down to flush for all the wall panels etc. I is kind of messy but I think it sure helps with the heat. The companies
that do it are usually associated with roofing companies.

YMMV

Also refrigeration companies. They build meat and vegetable coolers / freezers and use foamed in place insulation.

Oversteer is when you hit the wall with the rear of the car, understeer is when you hit the wall with the front of the car. Hp is how fast you hit the
wall, and torque is how far you take the wall with you when you hit it.

I did one unit of that and then I hired the guy that finished the job. That foam is softer than what the commercial people use. I won't comment on
the R factor I do not know that but there is a learning curve and it was quicker neater faster and about the same money to hire someone to do it.

YMMV

Having a spray foam contractor do the work means you'll have non-DIYer materials to choose from, with better fire ratings and lower VOCs, they'll
finish spraying the interior (assuming it's stripped, prepped and masked) in half an hour, and there'll be less waste.

Pick your battles.

That’s a lot like buying carpet or most other floor coverings Richard.
Agreed!

I foamed the walls of an old Econoline I had by tacking thin fiberboard to the ribs and leaving a few inches open from the top to pour the foaming
liquid in. It was a two part given my by Mortar Creek Plastics because it was out of date. They used it in boats they made for flotation. Once
dated, the volume by weight changed, the stuff foamed bigger. Since they foamed the boats by weighing it and then pouring it through a small hole in
the fiberglass if it overfoamed it busted the boat or at least deformed it. Worked fine in the truck, I didn't care that it foamed out a bit at the
top and the price was right. It did, however destroy the clothes I was wearing - I couldn't get the foam out of the fabric.
