I installed hardwoods on a concrete slab and certain boards started popping a week later. I have a feeling that the glue did not bond with the concrete. Does anyone know what I can use to stop the popping? I really do not want to rip up some boards.
Thanks

If you used the same glue and same technique through out, I would say the floor is not flat in the affected areas. The type of hardwood is it? It's engineered hardwood right? Maybe 3/8-1/2" thick, not solid hardwood?

Jaz,

Thanks for your help. I used engineered hardwood 3/8" thick. I used the same glue but probably did not put enough glue down. The floor is off a little. Someone mentioned to me that there is a epoxy that you inject into the hardwood. First you have to drill 1/8 hole in the hardwood then you inject the epoxy. The epoxy spreads out under the board and dries within 5 minutes. I am trying to find out what kind of epoxy and where I could purchase it. Thanks again.
