Hello, I have a question for this forum.

My house is from the 20s or 30s and has a pine floor that we are currently using. Unfortunately there is no subfloor. We are going to put a new solid wood floor over the pine.

My question is regarding adding a plywood base over the pine.

I want to run the new floor in the same direction as the pine. In order to do this, it is my understanding that I need to add plywood. I would like to use 1/4 inch instead of 1/2 inch. I have had different opinions on this, some saying that the 1/4 is fine, others saying that it is not enough.

Any thoughts on this?

Thank you for the advice

¼" is not enough.

FYI, every house has a subfloor. Your's happens to be pine planks. Read:

And I agree with Floorguy that 1/4" isn't adequate. I suggest a MINIMUM of 3/8" CDX grade plywood (which is LESS money than 1/4" and only 1/8" thicker). Make sure those pine planks are firmly attached with no squeeks. Screw down loose areas. Flaten the pine floor and install the plywood with a construction stapler.

Thank you for the advice. It is quite helpful.
