So I have sanded cherry and white oak to 220 applied the oil wiped dry let stand for 72 hours … plus, I want to apply a poly wipe on finish. So sanding for it I having a hard time as it clogs the paper, what am I doing wrong? I’ve tried wiping with mineral spirits, I’m guessing wet sanding is an option

Temp and humidity have a HUGE influence on drying times. How thoroughly did you wipe the application of oil?
Our temp/humidity here is MS can really change the playing field when using oils and wiping varnishes. DAMHIK.

wiped off thoroughly till dry then came back and wiped off the spots that wicked up, actually drying 6 days. I allowed extra time because South Carolina is an oven of humidity.

Is there a reason to sand the Watco? If it’s smooth I’d skip that step, but still allow plenty of time for the oil component to cure.

I use Watco under poly quite often on cherry, walnut, oak, and maple. When it is slow to dry I put it out in the sun for a couple of hours then vigorously rub it down with a clean rag to get every bit of excess oil off. If it is still tacky, repeat the process until it is dry and not sticky/tacky. You shouldn’t have to sand before applying poly but it needs to be dry and not tacky.

It is my understanding that poly is like varnish and needs a mechanical bond, that’s the reason I sand. how durable is the watco ? I may just skip the poly as it withstands water spills and alcohol. I will try the sun trick next time

“Poly” (in common useage) isn’t like varnish…it is varnish. So is the Watco. The durability of the Watco is very good…but the coats are very thin, and the oil component makes the film a little softer than just varnish. Anyway, the scuffing is sometimes needed for urethane finishes because urethane has adhesion problems, even with itself. But with the danish oil, letting it cure (at least a couple of days) and then applying the varnish should be OK.
