Hi I have just finished (last night) applying a coat of zenith matte poly to a white oak floor. The floor is white washed country white and sealed with 2 coats of poloplaz NSB. My problem is that in several spots I have "burns" where the activated zenith sat too long I guess. I want to apply a second coat- can anyone tell me if there is a solution to sanding out or fixing the discoloration caused by the hot zenith? I was working as quickly as possible, using a lambswool tbar but it still happened. The space is pretty big- 400sq feet-please give me any tried and true methods- the worst spot is in a high visibility area- Thank you in advance for your advice.

You mean the finish lifted the stain in spots where you could not spread it as fast as other areas?
I have had luck adding white pigment/paint to the next coat of finish. It will even hide a holiday, if you are careful.
