Q: We are in the process of a kitchen remodel. They have had to move some major plumbing areas, so I have a 6 foot by 1.5 foot trench in the middle of my kitchen that they are going to fill with concrete. I was planning on putting three-quarter inch solid pine floor down with a three-quarter inch subfloor. How long do I have to wait before we install now with the just laid concrete?
A: If memory serves me correctly the recommendation is 30 days. Keep an eye on it and perhaps in a week tape a piece of plastic over the concrete and leave it over night. Check to see if condensation has formed on the plastic. I don’t think you will have much of an issue with that small amount of concrete.
