hardwood refinishing questions

[mattgmann]

Hi all,

I'm about to start refinishing the floors in my new house. I am having a terrible time figuring out what finish to go with. The floors are red oak, mostly center cut, and about 60 yrs old. The do not appear to have ever been refinished, but are in decent shape. There are a few areas where the finish has worn through in high traffic areas, but it doesn't look like there's much, if any staining. Also, the combined area of the wood floors to be refinished is ~1000sq. ft.

Ok, now the details are out of the way. My basic options are water born, or oil modified urethanes. I'd prefer to go with water born, as I like the clear finish, and I've heard that oil based finishes smell for quite a while.

There are a few things I don't understand yet though.

1.With water borne finishes, do I need to apply a sealer first to prevent the wood grain from rising?

2.Also how many coats will I need to apply. With a new house, the budget is getting stretched thin, so I need to get a good idea of cost.

3.Will any sanding be required between coats? I'd like to avoid this, because the rental price for the sander is not cheap.

Prices of water born finishes seems pretty high in comparison with oil based finishes. The low end seems to be in the $50/gal range. I could use some recommendations on low cost, quality finishes. At $50/gal, giving 500sq ft/gal, 1000sq ft of floor, and 3 coats, I'm looking at ~$300 for finish alone. Is this right?

I'm not counting out oil based finishes. They seem to be about half the price of water born finishes. In fact I've found oil modified urethane as low as $100/5 gal. I don't want to base what finish I use on cost alone. But if anyone could recommend a decent quality oil based finish with an attractive price, I might go down that road.

Thanks in advance for any help,
Matt

I can take an hour to explain everything to you or I can send you to cobbledwoodfloors.com so you can read their receipe for wood floor finishing. They recommend oil based finish and well, so do I. Never did like anything waterbased being used on wood. Plus, water will raise your grain much more than oil based will - causing even more sanding. Being you are worried about cost, oil is the way to go. P.S. Never get in a hurry by thinking about using a roller to apply any wood finish. It will only cause air bubbles and makes for even more sanding.

Our contractor always does one coat of oil first and then 2-3 coats of water based. He says the oil adheres better and is the best option for the first coat. That's about as scientific I can get on this one, but our floors have always come out fine. We typically do 3-4 coats just to make sure, as we have pets that often scratch the surface. Hope this helps!

As far as I can remember - even as a child - oil and water do not mix. With water atop of oil, scratches can be quite a problem because the water does not completely and correctly adhere to the bottom oil base coat. I do not understand why a person would switch their finish receipe anyhow. The cobbled wood floor described on cobbledwoodfloors.com cost $135.00 a square yard- at that price, I would not mess with mother nature. Stick with one finish or the other. P.S. with 4 coats of oil, any minor scratches can be taken out with you rubbing your socks over it - cannot do that with water based.
