supporting a cantilever silestone countertop
hi - I'm trying to plan for a silestone counter top. At the end of the kitchen counter, I want about a foot of cantilever so that you can sit there with bar stools. I have 2 questions.
1. I assume that silestone will not support it's own weight cantilevering over the edge of the counter, and I'm planning a 3/4" plywood base. Will the silestone need this support?
2. If it needs the support, is 3/4" plywood enough or should I go thicker?
I looked at the specs on the silestone site, but I didn't see this explicitly.
thx for any help that you can offer!
