I live in Texas, Just outside of San Antonio in the Hill Country. I have no problems with moisture. Live on top of a hill, ground is entirely rock.

I have an garage apartment that we would like to put wood floors into. It is on a concrete foundation which is about 7 years old.

We do not keep the AC on all the time. What type of floors would be ok to put in there.

Would engineered floors be ok or should we just stick with new carpet.

The rest of our house has wood floors.

thanks.

Without an onsite consultation and evaluation, it is hard to say what will or won't work.

Garage concrete rarely has a plastic moisture barrier installed under the concrete before the pour. This makes concrete moisture vapor emissions, escaping through the surface of the concrete, high for wood flooring. There are moisture blocking/adhesive systems to overcome high vapor emissions.

Does that mean that the moisture content of the concrete is more important than the moisture content of the air in the room. Does it matter then if I am going to run the AC all year round or if I am only going to run it when we are going to use the apartment.

Thanks

Anything with moisture matters. Moisture, is woods enemy and friend. It needs some so it doesn't dry out and shrink too much causing cracks and gaps, while too much swells it making have no where to expand but upward, in what is called a buckle.

Engineered flooring helps, but is not immune to moisture. Especially the thicker sawn face, that is being produced more and more today as a thick wear layer is a big selling point. It defeats the purpose of an engineered somewhat.
