Messy, Messy, Messy - Cutting Foam

Any construction adhesive would work, Julie.

While we're on the foam insulation subject, how do you adhere the foam to the underside of the floor? especially after coating it with roof tar, etc?
Liquid nails? or have to screw/nail it to stay in place?

Julie

Hi there Julie,

I used Liquid nails construction adhesive, and finish nails around the edges of the foam, then coated it with roofing plastic cement.... It would have been a mess to coat it first then put the pink foam board on,like you said.... Don't know of anyone that did it that way.

Almost forgot... Happy Valentines Day

Something else that that work well would be an electric tire re-grooving tool like we use on the rear sprint car tires. It's just a heated loop of metal with a sharp edge.

Yup, Denny, that'll work also. Actually, rigid insulation foam is very easy to work with and not a mess at all.......................that is unless you cut it with anything that travels fast, i.e. sawblades, router bits, etc., etc.

hey loader,
that wasnt as messy as what we just finished.we cut and installed 40 sheets of 3 in foamboard insulation in on the celling of my shop and cut it with a table saw.i sweep up 2 garbage cans full of little shavings and dust.i dont ill ever get all the dust up.

Critter,

I once helped my brother insulate an A-frame home he was building. Didn't take us long to realize the tablesaw and broom method was a killer. We went to really sharp hunting knives and insulated that entire house (1500 sq ft) in one weekend. It was 2" thick foam and we put in two layers everywhere. What a job.................but at least we weren't fighting the static and all those foam shavings.

yup,
hindsight....but we tried a couple of cut with a knife but it got dull real quick and we the table saw worked good just messy.glad we are done.that job has been buggin me for a long time.didnt want to spend the money for the insulation but found it at a deal.40 sheets for a hundred bucks.had to do it to get the deal.insulated shop is nice.back on tear now
