Hello, looking for advice on how to attach this to the concrete/masonry pad underneath (used to be a pre-made one with tile) and into the plywood under neath it. Concrete adhesive didn't work. Thanks.

Why does it need to be attached?
 
Yeah, it's not likely to move, especially with a stove on it. However, if one insists, a few spots of JB Weld epoxy should hold it in place.

What stove is going on it?
 
Hope the top of that old hearth pad is pretty perfect. If you dent that diamond plate it will be really obvious. Even big scratches as you slide the stove into place could be bad. Aluminum reacts with concrete products so mortar is out.
