How To Prevent Epoxy Flooring From Peeling Or Delaminating

Updated: Dec 3, 2020

One of the main benefits of commercial epoxy flooring is that it requires minimal maintenance. Of course, for the best results, epoxy flooring does require proper installation procedures.

These procedures are easy to comply with, as most manufacturers provide data sheets that explain the necessary preparation and application tooling. But, when not followed, concrete epoxy flooring can start peeling or delaminating.

Common Epoxy Flooring Issues

Please note that virtually all of these concerns can be alleviated by simply following the epoxy formulator’s recipe or instructions for proper application.

The most common issue that might arise with your urethane cement flooring is that it may peel or delaminate. If this happens, it could be a result of the installers not using an epoxy primer, as this phase of the project is vital to allow a low viscosity resin to saturate the substrate.

Lack of proper mechanical abrasion to the existing floor can also cause an epoxy floor to begin peeling or delaminating, but this is explained in the product's datasheet.

Another potential problem is that bubbles or pinholes may form in the completed coating system. Most often, this occurs because of a lack of a bonding coat. The bonding coat creates a solid glue line and seals in any outgassing, which is a moisture vapor phenomenon that occurs during rising temperatures.

This issue can be resolved by having an epoxy flooring contractor thoroughly inspecting the prime or seal coat for any voids or pinholes before applying your finish coat. If any bubbles or pinholes are found the seal coat can be reapplied.

Additional Issues That May Arise

Sometimes you might find lumps or debris in the epoxy system. This typically occurs with different commercial epoxy flooring types as a result of improper cleaning or vacuuming before application. The remedy to this issue requires re-sanding and reapplication of the topcoat.

If you find the epoxy system is not fully cured or tacky, it may be due to insufficient mixing of the resin or improper usage of a mixing blade. Older mixing blades do not have sharp edges, thereby not allowing the coating to blend properly.

Things To Remember When Having Epoxy Flooring Installed

Any epoxy coating of good quality is typically a thermo-cured coating, which means that it requires the correct ratio of resin to hardener, as well as a mixing instrument that will allow for good shearing action for the required amount of time.

When using a pigment pack to color your resins, it must be blended thoroughly to create an even colorant. This process will also remove any clumps of powder or gel liquid, depending on the type of pigment used.

Preventing Peeling and Delamination

The most honest answer to how to prevent peeling and delamination is to have the floors installed properly in the first place. What this means can vary from floor to floor.

Each epoxy resin and hardener have different requirements, such as ratio, hardening time, and temperature. As long as the installer is aware of all these aspects and follows the manufacturer-provided datasheets, then peeling and delamination will be rare.

What is the Repair Process?

How hard it is to repair peeling or delamination really depends on the unique situation. Sometimes it can be patched or repaired with epoxy injection, but, due to the nature of the issue, it usually requires a complete reinstallation. In that case, it is essential you hire the right expert to make sure the flooring is installed properly to prevent delamination in the future, and to ensure that your value equals the epoxy flooring cost.
