Topic tags/keywords: polyurethane water based finish

Can I start a finish over oak and pine with regular poly to get the tinted look, then apply multible coats of water based poly for the fast re-coat times?

I think that you can. You just would need to make sure that the oil based has dried thoroughly then sand it with something like 220 so that the wb has something to adhere to. In my experience though, it is the first coat that takes a long time to dry. The subsequent coats dry quicker. I can usually get a second and third coat of oil based poly done in one day.

As stated above, just make sure it’s dry.

An easier solution is to use dewaxed shellac (zinsser sealcoat) first, then the wb poly. The shellac will dry in 40 minutes tops, and be ready for the wb poly. With the oil based you’re looking at a few days to a week or more of drying.

Just add some amber tint to the WB clear coat. Don’t complicate this simple process.

Question for Sam. What would you use for the tint? I’m asking because I want to add just of little color without staining. Thanks in advance if you see this.

I ain’t Sam, but I’ll answer anyway: water soluble dye stain like TransTint.
