Q: I built a new home last July. We have had ongoing problems with our engineered hardwood floor. Two certified inspectors state that the floor was installed improperly. 3100 sq. ft. Every single room has boards that are hollow, not glued down properly. Will these eventually pop since they aren’t glued properly? The builder says he sees no problem. Sure.. he didn’t pay for the floors!
A: I think it would depend in part on how many of these boards with no adhesion exist and especially so if there are several together in a group. I believe Bostik has an adhesive you can inject into the floor. A tiny hole is drilled through which an expanding adhesive is applied by a tiny tube. This would take care of any random boards that are hollow beneath. If you are talking dozens of them, that is another story.
