This is a picture of a piece of floor coating that buckled up and peeled away with the garage floor. The piece of coating is upside down and laying on top of the garage floor that it peeled up from. The coating that peeled is bowed because of the inward stress in the floor coating which is a natural phenomena. Resins are born for gripping, so as they dry they grip and pull the concrete towards itself. But beware of concrete that is not held together well, because if the resin grips to the concrete better than the concrete is holding itself together then the resin will rip the concrete from itself and buckle or peel like this picture.
You see, all floor coatings have an adhesion strength, and if the adhesion strength of the plastic is stronger than the concretes tensile strength (tensile strength is the concretes ability to stay stuck to itself) then the concrete will fail by crumbling or shedding from itself. The back of this piece of floor coating has concrete particles stuck to it because the floor coating did its job. It stuck to what it was supposed to. Unfortunately the concrete shed from itself. The proof is on the back of the peel. Therefore deficient concrete was the cause of this failure. But not all failures are caused by bad concrete. For example: if the back of the piece of buckled or peeled floor coating is perfectly smooth just like it is on the top then there was a bond breaker of some sorts (maybe contaminants) or there was insufficient concrete preparation and the result of not having a Concrete Surface Profile (roughness). This is simply one example out of many different types of floor coating failures.
Why did my garage floor peel?
Just like a detective needs clues to solve a crime the answer to that question is usually self evident when the evidence is examined.
