Would it be a good idea to put a concrete sealer on the concrete slab before putting on the hardwood flooring?

My condo is on the bottom floor. I’m changing the carpet into hardwood flooring. I have a concrete slab under the carpet. I was wondering if it would be a good idea to put some type of Concrete Sealer before putting on the engineered hardwood flooring and underlayment? Or is the underlayment enough to stop the moisture?

I’m going to assume this is not a basement but a slab floor. It will depend on if there are issues currently with dampness as to what you do here. Sealing it should not hurt in any case. a 6 or 7 lb underlayment will serve you greatly. But for an engineered floor I strongly suggest Dricore.

To produce similar results to Dricore less expensivly use Delta-FL it’s 50 cents a sq foot. then normal underlayment.

    I would do that and also lay down a vapor barrier.

    Hi JD
    I think I would contact the maker of your engineered hardwood. They would know better than anyone else. Better safe than sorry.
