"Soft" foam sealant

[noone70]

Hello

I need to find expanding foam that doesn't harden, but instead retains the same consistency as foam rubber once it has set. Does anyone know what it's called?

Preferably, it should be available in disposable cans so I don't have to buy a foam gun.

There are as art supplies:

One alternative might be CC-fönsterdrev, a type of slowly expanding foam rubber. I used it for a window door last week, worked well, but maybe a bit expensive as it took two rolls at 100 kr each.

This should be "half-elastic"

It is available from several brands. Google elastiskt fogskum

NOTE I have not tried it myself!

The difference between http://www.bostik.se/Products/Sealants/Foam-sealant/P0508 (which you linked to) and http://www.bostik.se/Products/Sealants/Foam-sealant/P0239 (which seems to be "regular" foam) is that the maximum joint movement is 20% vs. 5%, which is significantly more elastic but perhaps not quite like sponge rubber.

Danalim 580 mentioned above in the thread is recommended. I have used quite a lot of it, and it works excellently. Naturally not as flexible as CC-fönsterdrev and other expanding drev, but there are other advantages with foam.

Danalim 580 seems interesting and it appears to be the one that expands the most. P0508 also seems to be an option, but it looks like you need a gun for that and it doesn't expand as much. Found Danalim 580 for 260kr/bottle? Does anyone know what the price is for p0508? I've tried googling a bit but haven't found a price. Do you know of any online retailer that sells bostik/danalim at good prices?
