This video shows the true strength of our epoxy. When we say it has the strongest adhesion, we really mean it. In this video, the epoxy was applied to the floor and then a cement block was placed on top then the floor and the cement block were allowed to cure together. After curing, the bond was so strong that when the block was hit with a hammer, the epoxy bond DID NOT FAIL but rather the cement floor did. Talk about strong adhesion. This why we can offer you the lifetime warranty that we do.
