We purchased an engineered wood product, 5 ply, 1/2 inch to install glue down over concrete, at grade level. Called an installer to see if they would do the job, they recommend not glueing down over concrete due to cold winters and hot summers. They want to put plywood subfloor and nail to it. Do we need to do the subfloor or can we glue down? The product is warranteed for glue down above, at and below grade - I just don't want to have to redo it later.

How wide is the flooring? This would be my only concern as far as the nail down aspect. It sounds to me like the installer you called has never done a glue down and wants the extra $$ for putting in that sub floor especially if the install is at grade. Did he do a moistture test? Could this be the reason for the additional sub floor. If excessive moisture is found he might recomend sealing the floor, then 6mil poly, then the plywood and then glue down. Is the flooring able to be stapled down or is it a glue only? If it is glue only and he staples it it will void the warrentee. Just some things to think about and ask your installer.

Product is 3" wide planks. Can be glued, nailed down or stapled. The installer has not done a moisture test, just recommended it over the phone. We have done the moisture test and it is fine. The installer was more concerned about the temperature changes between summer and winter than anything else. I guess I won't hire him!:)

If you bought the material from a reputable dealer, and chose a reputable name you should have no problems if you follow the recomened install method. If you have a moisture cert this will help in any claims you may have down the road. I say find another installer, ask friends etc for recomendations, and make sure the installer follows the manufacturer installation instructions to a T! This includes the type of glue used, Poly if any is used etc. Any variance form the manufacturers instcructions will void the warranty! Be carefull, and all will be fine.
