Foam

[Tricksum]

Generally which type of foam would provide the strongest bond when glueing leather to it.

I think it depends more on the use before trying to decide which foam to use. What will it be used for?

If your going to glue to foam its more important to do the gluing right than the type of foam. Spray both sides with an even coat and let it flash off for a minute or two. If the glue soaks in spray another coat on one or both sides and allow it to flash off again. The press the pieces together and allow it to setup well for an hour or so. You should get a nice strong bond.

I'm just thinking out load here, but assuming this is his egg chair project and I think he said it was only 1/2" foam---


---I'm wondering if scrim foam, glued foam to substrate/scrim to leather, might not handle the tension of stretching it in better. Just a thought, I'll wait to hear from those with more experience with that situation.

Posted this but it didn't take so here goes again...

  I see this type of job like this. These are done in a factory with presses and forms that allow the fabric or vinyl to conform to the shape and hold things in place while the stretching is done. We as reupholsterers don't have this equipment and have to make due with what we have. Darren you may have a point with the sew foam (scrim) as you call it over yonder but there are two bonds here. One attaches to the foam/fabric the other to the foam frame. If either gives out then the job is toast. So where is the bond more likely to give way? I see it as the second bond foam to fabric. Again a form would help. I use sand bags as a little help when holding these things in place.
