I keep hearing not to put a water-based finish on any kind of oil.

Here’s some grain-filling advice from Charles Neil’s latest newsletter:

I will rub a good oil, like Arm-R-Seal, into the pores after the color is applied. This mechanical push along with the thinner oil forces the oil into the pore. Rarely does one coat do it. After the oil is well I can brush (foam) a water base finish or rub it on to further fill the pores. I like the water base as it is heavier and fills quicker. It also doesn’t shrink back like a solvent base finish.

Before I knew better, I put water-based on top of oil, and haven’t seen a problem yet. Is conventional wisdom no longer true?

I guess I didn’t know that was “convential wisdom”. I’ve used a waterborne finish on top of BLO several times without a problem. But for me it seemed the trick was to give the BLO plenty of time to cure. I usually wait 5-7 days (depending on temp) in this instance, whereas with solvent based finishes I usually only wait a day or 2.

My point was doing it without shellac.

I use oil based stain and water based polycrylic all the time. As long as the stain is thoroughly dry there’s no problem.

I think there is a saying, water on water, is AOK, water under oil is AOK, water on oil, you got a problem. Now, all you have to do is define “oil”.

I did water on top of oil on my kitchen cabinets with no issues. You just have to let it fully cure. I mean 100% fully cure, not just ”that ought to be close enough”.

These cabinets are an oil base stain with waterborne clear on top. The was applied a couple week before the top coat.
