I posted a question here about my idea for outdoor granite countertop:
I found a 2 cm countertop piece (without the thick L-shape edges) as it's just flat on all 4 sides. You could say it's unfinished but since the sides are all shiny, I like it the way it is.
If I put it on outdoor plywood and glue using granite adhesive, is that enough? I am afraid the piece still moves because the 4 sides don't have the thick edges.
