Hardwood flooring installed with Bruce EVERBOND
I'm sorry. I assumed the floor was wood. I did not think about being on concrete. If it's concrete more than likely the floor will fail. It may be a year or more or it could be a week. You cannot put solid wood on concrete without problems. You can call National Wood Flooring Assn. 1-800-422-4556.
They will answer any consumer questions. This way when you confront the contractor you will have facts from a reputible source, not just the internet. I would not pay for the job, if it is on concrete, until you talk to them.
