I,m about to install an ash strip floor. It,s a renovation.we,re living in the house.in order to limit enviromental impact to the family, my thought is to finish the floor in the following way: Sealer coat with traditional solvent based polyurethane,following coats with water based. I would go with water base all the way except that I like the rich color change that happens with oil based products. I would rather not stain with a water based stain, i prefer the natural color spectrum. Any thoughts on using the finishing products in this way?Thanks for any comments or opinions.

My feeling is that not much will even stick to solvent-based polyurethane. See what others have to say, but...maybe at least test it on a scrap or something before doing the whole floor. I'm of the opinion that oil and water don't mix.
Edited to add: You may try posting your question on Knots--the woodworkers web site. They probably have a lot of experience with various finishes and compatability. Good luck.

you don't say how much square footage is being coated the more there is, the more chemical gasses off to home environment it's not health food i coated a beam & deck ceiling w oil base poly some years ago, plenty of windows open, then stayed in the house woke up early am hacking and wheezing trained professional that i am, finally read the label on a can of poly "can cause chemically induced pneumonia" left the house, was ok few hours later...
look into "emulsion coating" by basic coatings it's a hybrid oil & Water borne which dries in 2 hours, very low odor similar to all the waterborne products oil content gives it some of the oil tone you're looking for self-bonding, it does not require a sealer coat like most water bases, so 3 coats are all wearcoats open windows and let house vent off after drying usually sand and first coat on first day, apply 2 coats on second day
might have problems mixing chemicals; oil, then water as you mentioned mfg's all recommend against mixing different brand products seen it done, sometimes gets opaque look, have seen a couple w surface going bad... there's also a water base tint product you can apply first to sanded floor deck, gives waterborne poly the look of oil haven't used it in a while, will try to remember the name, maybe someone else knows it offhand?
