My father has an older condo and recently spilled some cleaners on the floor, which cause it to buckle up horribly. He pulled up a few pieces and asked me if I could help him replace them...but I have no idea what these things are, not any kind of floor i've ever seen.
It looks like some of the pieces were almost glued down to the subfloor, since I can see chunks of it left over on the planks, but then there are also these strips that look like they were placed there on purpose, and almost fit in to each other. Someone said it looked like it was a "glue-down" laminate, but I've never heard of such a thing. I was hoping maybe someone on here might know what these are, or maybe an installer that has put it in before. I figure since it's probably old, I won't be able to find that exact floor anymore...but Im just curious at what it is .
Here are some pictures of it...the red is the underside of the floor, to show those lines of wood, that when peeled up, almost look like shims. The top is the natural finish.
