I recently purchased a new home in South Carolina, and was planning to extend the existing hardwood throughout the rest of the ground floor. Once I began to remove the existing carpet, I saw that there's no wood subfloor: the existing floor is glued to the concrete.
I want to use 3-1/2 in. hardwood flooring (not engineered), so in this situation my plan would be to:
- Remove the existing hardwood
- Install a vapor barrier on top of the concrete
- Lay down 3/4 in. plywood and secure it to the concrete
- Install a felt pad on top of the plywood
- Install the new hardwood
I haven't dealt with a scenario like this before, so I just want to be sure my understanding is correct.
