Does Buffing Make Wood floors Shine w/o putting more Poly on?
Need help!! The first coat of Poly went on great. The 2nd coat of Poly went on great too. It's Oil Based, Semi-Gloss poly("Pro"-finisher, Clear Semi-Gloss by Rustoleum, comes in the red can). After the 3rd coat, the floors had what looked like little bubbles or little things under the finish in a lot of places.
Does it matter that when putting each coat of poly on, no windows were opened, nor any A/C on....(I read that you need ventilation for the solvents to escape?) So for the 4th coat I opened some windows a little ...but the floor came out the same, maybe a little worse, because now there are skipped spots from the applicator and some scratches in a circular motion in places. But, it looks like the little bumps are showing up through,...it seems like they are in the same areas as before. The little bumps feel smoother, but if you run your hand over the surface it feels rough. So we are thinking that the last coat that had the bumps in it was not buffed out enough?
I read this, and wonder if this could have happened: "Semi-gloss poly has dulling agents in it that are at the bottom and have to be stirred in. Some cans have these agents settled so firmly at the bottom, so that it can't be stirred without staying in hard lumps." Could these little lumps/pieces be what is in the floor?
There are already 4 coats of poly on the floors. I'm afraid that a 5th coat will look too thick. Can it be just buffed to get the bumps out? Does buffing leave an unfinished looking surface, or will it still look as shiny as a fresh coat of semi-gloss poly? Will it have the same amount of protection as if it has 3 coats on it? Or in order to get rid of the bumps under the surface, will it have to be brought down to the equivalent of 1 coat and then need more than just another coat of poly in order to have the equivalent of 3 coats?
A lot of questions, ..hope someone knows the answers. Thanks!
