Dark spots on floor hot to touch

Q: We bought engineered bamboo hardwood flooring in February and kept it in the house until it was installed in March. It was glued down with the glue that the store recommended. Now dark spots are showing up in certain areas of the kitchen. Bubbles are now appearing on the darkened areas and the wood is hot to the touch.

This part of the floor does not have a full basement, but does have installation and subflooring. There does not appear to be any moisture anywhere. What could be the problem?

A: I’m not certain what is going on. That you say the spots are “hot” may be a clue. Is there some type of reaction going on between the adhesive used to install the floor and the adhesives used in the floor itself? I would definitely be calling the company you bought the floor from and have them come and inspect it.
