I have solid surface counter tops in my kitchen. U shaped with stove at the bottom of the U. The solid surface counter top right next to the stove has come up a little. When I press on the counter top it moves up and down 1/8". The front corner does. Rest of the counter top seems to be still attached to the cabinets.

How are the solid surface counter tops attached to the cabinets? And how do I reattach the solid surface counter top back down to the cabinet?

Looking inside the cabinet it seems like they used some clear glue, caulk to originally attach the counter tops. But not positive on that. The cabinets are particle board. It looks like I could shoot some Liquid Nails or other glue on top of the cabinets, edge and then put a heavy weight on top of the counter to hold it down. Wait 24 hours for the glue to dry. Yes? No?



My counter top is official solid surface. As we think of solid surface. Its made up, created material. Its not real stone. The top is a dark blue with lots of white flakes in it. And it has a 1/2" band of white along the front edge and 1/2" of the blue/flake below it. Looking up at the underside of the counter top it looks like the middle of the counter top is just 1/2" or so of the blue with a couple strips running across it to build it up to 1.5". And the edges are the full 1.5" with the built up blue-white-blue. It looks solid 1.5" from the front, but its really only 1.5" around the edges and just 1/2" or so in the middle. With a couple supports glued in.

OK. So I think the plan is to use levels to see if the counter top is level with it popped up or pushed down. Then shim and/or glue it down with Liquid Nails or this Super PL (polyurethane construction adhesive). And put a big heavy vise on top for 24 hours to hold it down until the glue dries. I don't think there was ever any shims between the counter and cabinet edges.

I now realize I probably caused the counter top to come up. The corner that came up is right where I lean when I am standing in that corner of the kitchen. And my butt and the counter top line up so when I lean back against the counter top, I push up a little with my butt. So over the years I have probably broken the original glue joint.
