moisture mitigation in a slab
jimechols

I have a home that was built in the mid 70's on a concrete slab. I've lived in the home for the last ten years and every winter (I live in northern Florida) I deal with a lot condensation on the windows when the temperature drops. The house was not vented at all and at the time I believed that the condensation was due to showers, cooking and the like. But we have started renovation the house I have noticed several things: If I put plastic down over the carpets to protect them, the carpets are damp after the plastic is removed. Where tile was removed standing water was found underneath. If plastic is laid on the bare concrete moisture forms underneath. Obviously I have moisture coming up through the slab. We want wood floors, so we absolutely need to put down a sealer. I've even thought about thin-setting kerdi fabric to the floor. Not sure if I could glue wood floor to that.

The floor manufacture recommends a Bostic product that is an all in one glue and sealer, but due to the cost of the floor, I want to be sure. Is there a product that can be spread onto the entire floor and then I could use the sealer/glue on top of that?

Why try to deal with water AFTER it has already gotten inside, why not keep it out to begin with?

For water to be coming through your slab would indicate that you've either got a high water table, poor drainage, or both. Figure this part of the equation out, then remedies can be discussed.

Don't install a new floor UNTIL you determine the source of the moisture and do something about it. We can't help you sitting in front of a computer screen, you have to call some local general contractors who know the area. Talk to neighbors and see if they have a similar problem. With further information you can determine what to do next.
