Why Is My Epoxy Floor Peeling?

Why Is My Epoxy Floor Peeling?

There are several reasons why epoxy floors may peel. Here are some possible causes:

Poor Surface Preparation: One of the most common causes of epoxy floor peeling is inadequate surface preparation. If the surface was not properly cleaned, degreased, or repaired before applying the epoxy coating, it may not adhere properly and can lead to peeling.

Moisture or Humidity Issues: Moisture or humidity problems can cause the epoxy to lift and peel. If there is excessive moisture in the concrete substrate or if the coating is applied in high humidity conditions, it can result in poor adhesion and eventual peeling.

Poor Installation:  If your epoxy floor is not installed correctly, this will cause adhesion issues and lead to peeling and/or chipping. You must ensure that the surface is free of dirt and contaminants, then apply a consistent amount of adhesive as specified by your manufacturer. Make sure you use enough adhesive across the entire surface to avoid bare spots or air bubbles.

Incompatible or Low-Quality Products: The quality of the epoxy products used and their compatibility with the substrate is crucial. If low-quality or incompatible products are used, they may not bond properly, leading to peeling.

Incorrect Mixing or Application: Proper mixing and application of the epoxy coating are essential for a durable and long-lasting finish. If the epoxy resin and hardener are not mixed in the correct proportions or if the coating is not applied evenly and at the recommended thickness, it can result in adhesion issues and subsequent peeling.

Weak Adhesion:  Epoxy is a two-part system that consists of a hardener and an adhesive. Although the epoxy may have been mixed to specified ratios, this does not mean it was applied correctly. If there wasn’t enough adhesive used for all of the hardeners, or if the ratio was off, your floor would fail. The entire surface of the epoxy needs to be covered with adhesive, without any bare spots. This includes between tiles.

Not Enough Coverage:  Epoxy is a very thin product that should only provide a protective layer of no more than 3mm thick. If your floor was laid over another material, such as an existing tile or vinyl floor, the thickness would depend on what was under it. If there isn’t enough epoxy to go around, then your floor will eventually begin to peel and chip as you walk over those areas.
