Why Is My Hardwood Floor Chipping

Heading down to texas where robert has got a flooring question.
Why is my hardwood floor chipping. This often leads to some head scratching trying to figure out how it happened. For example it s not uncommon for old floors to start peeling as the old polyurethane topcoat starts to deteriorate. Im having an issue with my engineered wood floors which were installed in my condo almost 5 years ago on top of the original cement floors which were already 20 years old. Well i laid engineered hardwood down about just a little under 700 square feet.
Peeling finish can be a frustrating issue for floor finishers. Why are my hardwood floors splitting. Nobody likes to see polyurethane peel especially just after refinishing the floor. And unfortunately that s when hardwood floor splitting also known as checking is most likely to occur.

I still acclimated my floors to the midpoint of my moisture range at 70 f so i don t have gaps in the winter or buckling in the summer. Without a protective finish the wood becomes hypersensitive to moisture and temperature changes which leads to splintering.
I am having issues with polyurethane peeling off my hardwood floors. So the idea of refinishing a hardwood floor did not scare me. Up until recently my eng wood floors looked great with a smooth surface and sat perfectly flat and solid onto of the cement. If you ve noticed splits in your hardwood floors you re probably a little distressed especially if your floors are on the new side.
Sometimes the coats will lay down flat and smooth and look good after the floor finisher has left only to receive a call later that the finish is separating from the floor. I install wide plank flooring when it has a slightly high moisture content. And the problem is is the top 3 millimeter layer is starting to peel up on a few of the boards. Engineered flooring or quartersawn flooring is the best choice for my home because they re less susceptible to movement.
I used an oil based stain and followed that with an oil based poly. I have refinished multiple dressers tables chairs beds etc.
