How can you repair a raised kitchen counter due to water damage?

The home owners before us apparently let water stand on the kitchen counter top and it has started to raise. I don't want to have to replace them so my question is, is there any way to repair the damage?

    Laminate countertops are a thin covering of laminate glued onto a particle board type sub-surface. If the sub-surface hasn't swollen from the water, you can squirt construction glue into the seam, put wax paper (with a thin coat of vasculine on it) on top, and put something very heavy on top the entire seam. Wait at least 12 hours before removing.

    Good luck.

      When you press the two sides of the joint together they should lie flat. If they are swollen the joint will be raised and they will never lie flat. You could still glue them down but you would have a raised bump that will never go away.

    I would try to lift it up more and then put a contact glue on both sides and weigh down until it holds properly. Use a flat stick to force the glue underneath. Put lots on the edges and be sure to wipe the top clean as soon as you are done working with the glue.

    I agree with Bijous_2010. If you push down on the laminate and it goes flat and smooth the substrate has not swelled. Use a putty knife or anything flat an gently pry the laminate up a bit so you can squeeze the construction adhesive under it. Use a rolling pin or flat board to flatten it out and allow the glue to grab. Wipe off any squeeze out with rubbing alcohol. Put some plastic wrap/wax paper over it and weigh it down for about 24 hours.
