Has anyone used 9lb foam as decking in cases? Are there issues with fabric covering? Is it sturdy enough to hold mounts? I'm doing some tests for upcoming work and looking for a source of 9lb foam. I know Small Corp makes an 'Ethadeck' consisting of alpolic, foam and fabric, but I can't afford their fancy ways. My supplier has 2" but won't slit it into 1" planks. Is it available thinner? Has anyone tried HDPE cutting board material or is that too wacky?

We have been using ½” 9 lb Ethafoam on top of ¾” medex for our decks and back boards when we need to use pins. It will hold small mounts and for heavy mounts we drill back into the medex. We attach the fabric with staples on the under side of the deck. Our suppler is BB Bradley 440-354-0039. They still have Dow Chemical brand Foam.

The Detroit Institute of Arts has used 1/2” 9 lb in the same way, for the same benefits, as Philip has described. Our supplier is American Excelsior. Google them and you’ll find a contact number for your area.

Re: [mountmaking-forum] Re: Source of 9lb foam? Then are you sealing the Medex with Marvelseal or paint? Steve

RE: [mountmaking-forum] Re: Source of 9lb foam? We have been sealing with a clear acrylic water based varnish but we are now covering our decks with Marvelseal. This is a very big issue for us right now. What are other museums using?
Contact Sealed Air () and find a sales representative in your area. The rep should be able to hook you up with a fabrication house that will either slice a plank of 9 lb foam. Or if you like, you may be able to purchase a sheet of their 1.5" foam. Keep in mind that the density of these foams are inconsistent along the edges of the fabricated planks and you may find the sniped end unusable (usually the last inch or two).
This foam hold mounts very well, but you may have to add a second support foot along a single rod to prevent it from rotating. You may also want to make sure your post is long enough to penetrate the thickness of the foam and attach into a more
