   Bostic Makes some silicones that are low VOC (we call them Hippie Caulk) You can get it through Stock Building Supply. Their panel adhesive is really great too.

   ShelterNerd,

   Thanks for the tip. I'll contact them and call around to see if it's available in Canada too.

   Cheers,

   Penny:

   As a Certified Corian Fabricator and a Certified Zodiaq (DuPont's version of Ceasarstone) Installer, I would advise you to skip the plywood underlayment, it is unnecessary and may cause more problems than it's worth.

   I've installed lots of Zodiaq with dime-size dabs of silicone spaced every 12-18" without a single callback. You don't even have to do the back/wall edge. Silicone is oderless and inert after it sets up and has excellent adhesive strength while accommodating wall/top movement. It stops smelling in about a half hour.

   I wouldn't use mechanical fasteners, but if you've got your heart set on it, this is the only way to go:

   If you're still set against silicone, go to http://www.daniclamp.com and order some High Tack MS Polymer High Grip adhesive. It has no isocyanurates, solvents, phitalates or silicone and is suitable for adhering natural stone, according to the manufacturer, Den Braven sealants.

   You didn't mention it, but the methylmethacrylate (Integra) adhesive for deck seams will have the kitchen smelling like a Vietnamese nail salon for a half an hour or so. However, like epoxy or polyester (smelly too), the adhesive will be inert when cured.

   Good luck,

   Kowboy

   Kowboy,

   Thanks for all the info. I was steering away from silicone because of what I read in a FineHomebuilding.com article saying it didn't have good adhesion to wood. There was no article specifically on adhesives for the kind of application we're talking about but here's the article link:

   http://www.taunton.com/finehomebuilding/how-to/articles/making-sense-of-caulks-sealants.aspx

   But seeing that both you and Shelternerd have had good experiences with it made it is the way to go.

   Great video too. It's the cabinet maker that wants to use the plywood underlay and it took a while to find somebody local to do low-VOC cabinets and it's a style that he's pretty committed to. There is certainly some demand for green building here in Toronto but there still aren't too many builders so it might be a compromise we have to make. And in that case a mechanical attachment might make it easier to disassemble in the future. I've never done a mechanical attachment before so the video was good to see.
