The finish has cured for 3 weeks now and the table was being used. I noticed a small discoloration in the center of the table tonight which I thought was dried milk. (my son who is 1.5 years old had his milk cup on it earlier today) I scratched what I thought was milk with my finger nail from the surface of the table, but it wasn't dried milk. The discoloration was actually a section of poly that had lifted from the surface of the table. When I scratched it with my finger nail, it spread into a MUCH larger area. I cant tell for sure but I think it went down to bare wood (not just an outer layer pealing off).
I need to resand the entire top and restain. And refinish with poly. What a big f---en pain in the a--.
Why did this happen? I think it may have to do with not letting the stain dry (alcohol) enough before applying the poly, but I'm not sure. You can put an oil based poly over a water based stain, right?
I think I have had it with poly. I am either thinking about giving the poly (minwax) one more try or I am gonna apply lacquer (Deft brush on) on the top.
