Cracks between boards shinier than floor after second coat of poly

Q: After our second coat of satin poly there are shiny places along some of the cracks between boards. We waited 24 hours then used a pole sander with 180 grit screen to sand after the first coat. My theory is that these are low places where the poly pooled. Continue reading Cracks between boards shinier than floor after second coat of poly

Third coat flaking due to contaminant (soap) used between coats

Q: We had our hardwood floors refinished over the summer and they are starting to flake. The floors are scratching easily and you can peel away the poly with your finger nail. Continue reading Third coat flaking due to contaminant (soap) used between coats

Finish didn’t chemically bond and is lifting off

Q: I am having issues with polyurethane peeling off my hardwood floors. I have refinished multiple dressers, tables, chairs, beds, etc. so the idea of refinishing a hardwood floor did not scare me. I used an oil based stain and followed that with an oil based poly. Continue reading Finish didn’t chemically bond and is lifting off

Polyurethane doesn’t look thick enough

Q: I recently had my wood floors sanded and refinished with 3 coats of polyurethane. I was expecting the polyurethane to look a little thicker than it does. Should I be able to feel the edges of each board? It just seems like all you would be able to feel when you rub your hand on the floor was a nice thick coat of polyurethane.

Fish eye bubbles in epoxy coating



Q: My builder was required to resand and recoat my timber floors with a full gloss epoxy coating. This is his third attempt due to what I believe are fish eyes appearing.

Yellow streaking after 3rd coat



Q: My daughter had her floor sanded and recoated. After the first two coats everything looked great. The contractor said he wanted to add a 3rd coat so they said okay.

Duller finish in touch-up area



Q: I recently applied 3 coats of oil-based poly from *****, clear satin, to my new red oak floors. The poly looked good, but there were a few isolated areas that needed to be refinished, where poly had pooled a little and formed a small line/berm. These areas appear duller. Continue reading Duller finish in touch-up area




Stepped on finish before it was dry and left a dull footprint



Q: We just had our oak floors sanded and re-finished. The guy did a great job. Today in the morning he put the last glossy/shiny finish – looks wonderful. We came home after 7PM and I tried to get to the bathroom. The floor looked to me like it was dry. But in one spot my foot got stuck, it wasn’t dry enough, and I left a dull footprint on this beautiful glossy finish. Can I fix it somehow? Continue reading Stepped on finish before it was dry and left a dull footprint




Bubbles only coming out of the soft grain



Q: A job we sanded was first “popped” then stained. After the first coat of poly I noticed bubbles coming out of certain boards. And the bubbles only seemed to be coming out of the soft grain. I did a light sanding and put on another coat of oil-poly satin and had the same issue. This time these were different boards. There were about a total 4 boards with this issue. It seemed like the grain was rejecting the poly. They were BB sized bubbles. Continue reading Bubbles only coming out of the soft grain
