Um ok, you are in some deep ****. I do a lot of poly on custom furniture jobs that I get. First off, let me say, minwax is ********. Almost anything else is better. I like Zar, but tough to get in the big buckets.
I have never done a floor with minwax, wait I never polyd a floor by myself at all, but used the floor minwax on custom french doors. What a damn nightmare. I wouldn't even try it, but this was for a customer who was set on this **** and actually provided it for me.
So same story as you. Stain, minwax by the way. First coat of poly, yea decent. Second coat, holy ****, my brush is having a tough time, almost like its pulling. Ok whatever, done. Come back next day to flip the doors, can't second coat looks dryish, feels gummy, so I'm like WTF. I put my palm on it and give it a slip, the finish comes up. NO EFFIN WAY.
Long story short, I blew a gasket. It sort of cured a week later. When I was installing the door, I nicked a section with a hammer when driving the hinge pins in. What I saw was beyond belief. The top cured, under it though, the poly was still gummy. Somewhere on the can or specs it said 30 days for a full cure. EFFFF that.
I came to the conclusion that the first coat did not fully cure, even though I was able to sand it. Second coat sealed the first, and now it can't fully cure. Bottom of second coat also got trapped as it cured from top down. I have a feeling this **** was designed for the big box shopper that would do one coat, maybe even the stain mix BS, and call it a day.
