oil over water finish question

14 years ago

I'm an idiot. I finished a section of oak flooring with water-based poly and it doesn't match the amber coloring on the rest of my oak floor finished with oil-based poly (no stains were used).

If I understand correctly, I can put oil-based over my water-based once it fully cures. If I do, will the oil-based give it that amber coloration even over a layer of water-based poly, or do I need to sand down to the wood so the oil-based poly can come in contact with the wood?

Thanks for your help! (asking here since this really applies to wood more than flooring I think)

Sand lightly, so the OB can adhere to the WB. Look on the label of the WB, actual drying time for recoating may be longer than drying time to touch.

You will get the ambering.

The water-based coat will have dried 14 days by the time I can get back to this, and the can says that's enough. I need to fill some spots and sand anyway, so this works out well. I'll just do my final coats in oil-based instead of water-based. Thanks!

Hi,
You can also buy some trans-tint "amber additive" and put several squirts of it in the acrylic, and if the color's satisfactory, finish the job with it. This colorant was developed to give crystal clear finishes an old-time golden oil varnish hue.
I've used it; the first coat looks OMG bad, but settles in with a second coat.
