Product for refinished subfloor to help it resist damage & wear?

jlc102482September 13, 2010

We are planning to remove the linoleum in our kitchen, laundry room and butler's pantry to expose the circa-1940 tongue and groove subfloor underneath. We'd like to refinish it and use it as the primary floor in those three rooms.

I'd like to know if there is any certain type of product we can apply to the subfloor to help it resist better dents and dings. The subfloor is pretty might be pine. I am able to make a little dent in it with my fingernail fairly easily. I am okay with some "character" on the refinished subfloor, but I want to make sure that we don't end up with a really beat-up looking mess after a few months. Heavy kitchen appliances, an undeclawed cat and my high heels are some of the things this floor will have to endure!

Does a product like the one I'm looking for exist?

If the wood used for the subfloor is so soft that you can dent it with your fingernail, I think you're likely to be disappointed with its performance no matter what you do, especially in a high traffic area like the kitchen. Multiple coats of polyurethane will help, but the truth is subfloors are not intended to be the finished surface. The effort refinishing would take will never be rewarded with a good floor surface.

What you are describing is probably underlayment. The subfloor should be below that and on top of the floor framing.

Underlayment is often 1x4 T&G fir boards. When sanded it can be beautiful and quite serviceable but it will wear fast in a kitchen especially near the sink.

I am using my Douglas Fir subfloor and it is so beautiful! You can't find the old growth wood they used back then to make such a beautiful floor now. I think you should go for it, and if it doesn't wear well, you can put a harder floor on top in 3 years or 5 years or 10 years, or however long it takes to look bad. My main doorway floor is pretty scratched after 5 years of my dogs tracking in dirt, but it still looks WAY better than any newer fake stuff you could buy. And although it will never be "perfect" I definitely think it has a couple more refinishes left. Advice I would give, though, is definitely keep a rug over the main walkway, my floor would look much better if I had.

You haven't confirmed that the material is fir but if it is I would finish it with an oil-modified, solvent-based (commonly called oil-based) varnish. Polyurethane Varnish will provide a hard finish and Spar Varnish will provide a softer less brittle finish which won't resist abrasion as well but it should take dents better without separating from the wood.

I'm not sure if it's fir or not, but I will plan on using the polyurethane varnish - and rugs for the sink area and in front of the door! Thanks for the help, everyone.
