Shaping spray foam

[Rwnielsen]

Don't forget pawn shops on single use power tools. They can be a goldmine. I'd think a hedge trimmer would go for cheap

Sometimes you can even find your own tools there!

Sadly, that's all too true

If you have a sawzall here are blades to cut spray foam. Your local builder supply may have them also.

Interesting that they have different blades for open- vs. closed-cell foams. I wonder what makes those sawzalls so expensive.

That's what the pros who foamed my ceiling used. It still didn't look fun or easy, but it got the bulk of the job done. I used a curry comb to do a little extra shaping and it works well for small areas. It's hard, miserable work, so I'd suggest you try to fool some friends into helping you!

Closed cell foam is as hard as a rock once it dries. It would be harder to cut. Usually used in metal buildings. Open cell is softer.



The sawzall says Milwaukee on it. That's why. Harbour Freight might sell them if it's a one use item.

The curry comb works well. They use them to clean off the 2x4's ect so the drywall fits tight.


Free beer and food might attract willing helpers but it may not work twice on the same people.

A sanding disk on a side grinder works, actually quite well. Use the heaviest grit you can get. I think I used a 24 grit. It will make a lot of dust, make sure you have a good mask.

Can spray foam be smoothed out as you're spraying it? I know you spray it on and it expands but, could someone else follow along with a piece of cardboard and smooth it out? Something tells me I'm missing something but I'm curious.

From my point of view, that is certainly not how I would ever treat anyone that I called my freind. Now if we can expand the category to relatives by marriage, I am so in...

Having attempted that with spray foam in a can, I'd say that would be a big fat mess

That's the kind of answer I was hoping for, thanks

I certainly appreciate the time invested for all of you that responded. Decided against the spray foam because of it's price, availability, mess, respirators and just major craptastic work to finish it. Plus the cementing permanently everything in the walls it became a big nope for me,
Am going with pink rigid foam on walls and doors plus Noico and the peel and stick insulation.. Am going to cut some holes in the doors and try to fill them with big gap foam, will fill the chair rail voids with it also. Using the Noico peel and stick 80 mil and 320 mil insulation and everything is in layers . Floor insulation will be layers of 1 inch pink rigid with a layer of 2LB mass loaded vinyl. The thud factor is great with this one.
