Epoxy Floor Peeling: Causes And Solutions

Why is my epoxy floor peeling? Learn the causes and solutions

Although epoxy floor cures into a shiny, beautiful finish, improper treatment can affect the texture and appearance of your floor, leading to various problems, including epoxy floor peeling. So what is epoxy floor peeling, and how does it affect your floor? Keep reading to discover the answers.

Epoxy Floor Peeling

  • Epoxy floor peeling occurs when sections of epoxy flooring begin to detach or tear away from the underlying surface. Peeling results in an uneven and unprofessional appearance that may cause damage to the concrete floor underneath.


  • Several factors are responsible for epoxy floor peeling, some related to the conditions in which the flooring was installed. High or low temperatures and high humidity levels can impact the curing process of the resin and hardener used in the epoxy flooring. For example, high humidity leads to moisture buildup in the concrete substrate. When this moisture seeps through the epoxy, it begins to peel.

Temperature changes can also exacerbate moisture problems by causing condensation to form on the surface of the flooring. In addition, extreme temperatures can lead to epoxy floor peeling. When the temperature is either too hot or too cold, it can affect the curing of the epoxy. Improper curing results in the epoxy not adhering properly to the concrete substrate, leading to peeling and uneven resin.

Tips To Prevent Epoxy Floor Peeling

  • Professionals should carefully prepare the surfaces before and during application to prevent epoxy floor peeling. To ensure that your new epoxy flooring remains intact, the installer should take the following measures:

Thoroughly Clean Surfaces

  • Even if you have already washed the flooring before the installer arrives, a professional should thoroughly clean the surface to remove any dirt, dust, or debris that risks the adhesion of the epoxy. Specialized cleaning solutions and equipment ensure the surface is completely clean and free of contaminants.

Preparation Of The Concrete Substrate

  • The next step is to prepare the concrete substrate by properly profiling its surface. This involves creating an adequately porous surface to ensure the epoxy adheres well. To achieve this, a professional installer uses a grinder to roughen up the surface of the concrete.

This process helps increase the surface area for the epoxy to adhere to and opens up the pores of the concrete, allowing the epoxy to penetrate and bond more effectively.

Consider The Weather Conditions

  • Working in the best weather conditions is another important factor in preventing epoxy floor peeling. Weather conditions can significantly impact the curing process of the epoxy. Therefore, professionals ensure that the temperature and humidity are optimal during application.

Sometimes, the installer may use specialized equipment such as dehumidifiers or heaters to control the temperature and humidity levels during application. By working in the best weather conditions and ensuring that the epoxy cures properly, a professional installer can help prevent epoxy floor peeling and ensure that your new epoxy floor has a professional and even appearance.
