Hi,

You may want to try using Elmer's Probond Polyurathane Glue. This glue is very strong and will requires some humidity to work - the instructions will ask you to wipe a damp cloth over 1 or both surfaces.

The glue will expand when setting and will fill in any voids. The only problem is that it is not a quick setting glue. I usually glue, and after 1 hour, wipe off any excess that expands and then let cure overnight.

I got my glue at Home Depot.

Hope this helps.
