I put this floor down approximately a month ago. Everything went perfectly and it looked great. I got the batch from my local Lowes.
Yesterday I found an area (approximately 1 to 1.5 feet square) that looked like someone had let an incompletely washed out paint brush leak and dry. It looked like it would wipe up easily, but after going at it (in this order) with water, mineral spirits, acetone, carb cleaner, and a razor blade, I have concluded that the epoxy has chemically reacted with something.
The white area is just a strong as the epoxy. It feels like epoxy except that it is ever so slightly raised. It is as if whatever was there actually swelled the epoxy slightly and made it blush. Sliding a razor blade across it to make it level just reveals that the epoxy underneath (level with the rest of the floor) is white too, so this isn't just something sitting on top of my floor.
What in the world could have done this?
I checked with the contractors that were working on my house and as I suspected everything they have is water based paint. I can't imagine that having this effect. The only other thing they had in the area was drywall compound.
At some point previously there may have been a bag of potting soil sitting in this spot, and the pattern of the white spot looks to me like the pattern that a wet piece of plastic makes when placed against a water tight surface (areas of contact with the surface with interspersed pockets of air). I don't think it the bag was damp, but it could have been.
The only source of moisture I can think of would have been if our cat peed on it. Can cat pee react with epoxy? (if so I need to know because I was considering putting the cat's litter box out there).
If not, what does react with epoxy that makes something that looks like this?
(Pictures coming in next post after I get them resized for the board/forum to make them acceptable attachments.)
This is the room ... it is a utility room in my basement...
These are the pictures of the spot (ignore the encapsulated moth - that was the one flaw in the whole floor before this spot appeared)
