What adhesive to use for Sorbothane?
I'm building a multi-layer platform for my TT - 2" HDF (yes, not MDF) followed by a 3/16" layer of Duro 30 Sorbothane, followed by a 3/8" sheet of granite. The HDF is smooth finished, but the granite has one smooth side and one side that would require a fill type adhesive.

I'd like to know what non water-evaporative adhesive I can use on Sorbothane. In the HDF layer I was wondering if I could use something like 3M Spray 80. In the granite layer I'm not sure what I could use. Both interfaces would require high bonding strength due to the nature of the weight involved.

3M 467.

That's actually the same adhesive.

Okalee dokalee,

Hmm, I hadn't thought of tape. I thought tape would have a higher possibility of failing (peeling away under the weight of these materials). After I posted this I spoke to a support person at the place where I bought the Sorbothane. He said that for the Sorbothane to HDF interface, 3M Spray 80 shoukd work well, and that for the granite layer I should use Gorilla Glue (!) as I would probably need some gap filling there.

467/468/200 are insanely strong adhesives- the only issue is that once you touch surfaces, there's no chance to re-position.

The Gorilla glue is a single component urethane adhesive. It dries by a reaction with the moisture in air. There are many urethane adhesives that would do the job on a porous surface such a granite. A two component urethane is 3M 3532 You would also be able to use many epoxy adhesives. 3M 2216 is a high strength epoxy. A spray adhesive could work but would have no gap filling properties and have less surface bonding strength but you probably wouldn't have a problem with either approach as you will have a fairly large surface contact area either way.

Why not use ones that Sorbothane manufacturers recommend?

That would be entirely to easy, to follow the manufacturers recommendations! Where is the creativity in that, how will he know how to screw it all up!
