My question is related to repairing polyurethane on floors. I apologize for posting it here, but I’m hoping techniques used for furniture can be applied to floors as well. If it is inappropriate to post hear, please let me know.
I finished a final coat of Minwax oil-based, semi-gloss polyurethane to a section of my home. 95% turned out to my satisfaction with the following exceptions:
1) What is the best way to remove “debris” from a finish and repair it so that the repair appears seamless relative to the final coat?
2) I have two or three small holidays in the finish where insufficient polyurethane was applied. What is the best way to apply additional poly so that it melds into the final coat, seamlessly.
Thank you for any assistance that you can provide.
Regards,
Debashis

Debashis,
You didn't say what the debris was. If it's some stray contaminants, I would sand the area with 220 followed by a maroon scotch pad. The idea is to give the urethane some tooth for adhesion.
On the holidays you might just get away using the scotch pad.
I would make a small pad for blending in the area that had the debris. Just go over it lightly and don't work it too much. As long as it's the same sheen, it should blend well. The same goes for the smaller areas. A small finger bob made of soft cloth would work well here.
If you do use a pad or bob, be sure and dampen it first with a bit of mineral spirits.
I prefer a pad for this as it won't leave any brush marks.
Let us know how you make out.

Peter,Thank you for your reply. Just to make sure I understand your comments correctly, am I to use the maroon scotch pad, dampened in mineral spirits to apply the polyurethane?Also, The debris that I mentioned consisted of a spider that had landed in the polyurethane while it was curing. After removing the spider a few days after applying the urethane, I sanded the area with a "0000" steel wool. Unfortunately, the sheen did not match exactly and as a result one can spot the area in daylight. Should I go over the area again with a maroon scotch pad?Regards Debashis
Debashis,
You misunderstood. The scotch pad was only for abrading the surface. If the debris is gone make a small pad out of some soft cloth. Make sure it has no wrinkles in it Add a little paint thinner to it , tap it against your hand to distribute it and then add the urethane to it.
Lightly apply the urethane with this pad over the area that doesnt match. After it's dry it should blend. If not do it again. That should do it.
Make sure you don't leave your oily pad laying around. Shake it out and let it hang out to dry. Better to have to make another pad than have a fire.
Good luck.
