ปัญหาพื้นพียู หรือพื้นอีพ๊อกซี่ร่อนเกิดจากอะไร?

70 per cent of the floor problems are caused by poor installation, poor evaluation of substrate and skip fixing the problem on the substrate properly before the overlayment. Examples of problems are excessive moisture from the ground, lack of good cleaning procedures before the overlayment, and poor substrate preparation. All these are the common cause for epoxy and PU floor to fail after few month of installation.
