Epoxy Over Self-leveling Concrete: the best combination

Epoxy Over Self-leveling concrete

Epoxy and self-leveling concrete are two popular materials used in flooring applications.

Epoxy is a two-part coating made of resin and hardener that is applied to a surface to create a durable, protective layer.

Can You Put Epoxy Over Self-Leveling Concrete?

Yes, epoxy can be applied over self-leveling concrete to provide additional protection and aesthetic appeal. Epoxy over self-leveling concrete is a popular choice for commercial and industrial flooring applications because it provides a durable, easy-to-maintain surface that can withstand heavy foot traffic, chemical exposure, and abrasion. 

How to Prepare for Epoxy Over Self-Leveling Concrete Installation

Surface Preparation

Before installing epoxy over self-leveling concrete, the surface must be properly prepared to ensure a strong and durable bond.

This involves cleaning the surface thoroughly to remove any dirt, debris, or other contaminants that may interfere with adhesion.

The surface must also be free of any cracks, holes, or other defects that could compromise the integrity of the flooring system.

Moisture Testing

Moisture can also affect the adhesion of epoxy over self-leveling concrete.

Before installation, moisture testing should be conducted to ensure that the concrete is dry enough to support the epoxy coating.

Moisture meters can be used to measure the moisture content of the concrete.

If the moisture content is too high, additional time may be required for the concrete to dry out or a moisture barrier may need to be applied.

Repairing Defects

Any defects or imperfections in the concrete surface must be repaired before installation.

This may involve filling in cracks or holes with a suitable material, such as a patching compound or cementitious repair mortar.

It is important to allow sufficient time for the repairs to cure before installing the epoxy coating.

Grinding or Shot Blasting

To ensure proper adhesion, the surface may need to be roughened through a process of grinding or shot blasting.

This creates a surface profile that allows the epoxy coating to bond more effectively with the concrete surface.

Primer Application

Before installing the epoxy coating, a primer may need to be applied to the self

How to Install Epoxy Over Self-Leveling Concrete

Mixing the Epoxy

The first step in installing epoxy over self-leveling concrete is to mix the epoxy resin with the hardener according to the manufacturer’s instructions. It is important to mix the components thoroughly to ensure proper curing and adhesion.

Applying the Epoxy

Once the epoxy is mixed, it can be applied to the self-leveling concrete surface using a roller or squeegee. It is important to work quickly and systematically to ensure that the epoxy is spread evenly across the surface. The epoxy should be applied in thin, even layers to prevent bubbling or pooling.

Adding Decorative Elements

If desired, decorative elements such as colored flakes or metallic pigments can be added to the epoxy coating while it is still wet. This can create a unique and customized look for the flooring system.

Allowing for Curing Time

After the epoxy coating is applied, it must be allowed to cure according to the manufacturer’s instructions. This typically involves leaving the surface undisturbed for a specified period of time, during which the epoxy will harden and cure.

Applying a Second Coat

In some cases, a second coat of epoxy may be necessary to achieve the desired thickness or to provide additional protection. If a second coat is needed, it should be applied after the first coat has cured completely.

Final Inspection

Once the epoxy coating has cured, the surface should be inspected for any defects or imperfections. Any areas that require touch-ups or repairs should be addressed before the flooring system is put into use.

How To Maintain Epoxy Over Self-Leveling Concrete?

Regular Cleaning

One of the key benefits of epoxy over self-leveling concrete is its ease of maintenance. The surface should be cleaned regularly using a soft-bristled broom, a mop, or a vacuum to remove any dirt, dust, or debris. For more stubborn stains, a mild detergent or specialized cleaner may be used.

Preventing Damage

While epoxy over self-leveling concrete is highly durable, it can still be damaged by heavy impacts, abrasion, or chemical exposure.

To prevent damage, it is important to avoid dragging heavy objects across the surface, to use protective mats or pads under heavy equipment, and to clean up spills or stains as soon as possible.

Repairing Damage

If the surface does become damaged, it is important to address the issue promptly to prevent further damage or deterioration. Minor scratches or scuffs can often be repaired using a touch-up kit or by lightly sanding the surface. More serious damage may require professional repair or even replacement of the flooring system.

Reapplying the Epoxy

Over time, the epoxy coating may begin to wear or fade due to normal wear and tear. In these cases, it may be necessary to reapply the epoxy coating to restore the appearance and protection of the flooring system.

This can typically be done without having to remove the existing coating, but it is important to follow the manufacturer’s instructions carefully and to work with a trained professional.

Benefits of Using Epoxy over Self-Leveling Concrete

Improved Durability

Epoxy over self-leveling concrete is a highly durable flooring system that can withstand heavy foot traffic, machinery, and other types of wear and tear.

The self-leveling concrete base provides a strong and stable foundation, while the epoxy coating acts as a protective layer that is resistant to scratches, cracks, and other types of damage.

This combination creates a long-lasting and durable flooring system that can withstand the demands of various environments.

Chemical Resistance

Epoxy over self-leveling concrete is highly resistant to chemicals, making it ideal for use in industrial and commercial settings.

It can withstand exposure to harsh chemicals, such as acids, solvents, and oils, without becoming damaged or discolored.

This chemical resistance also makes it easier to clean and maintain, as spills can be easily wiped up without leaving stains or marks.

Aesthetic Appeal

Epoxy over self-leveling concrete can also enhance the appearance of a space. The epoxy coating can be customized with a variety of colors, patterns, and textures to create a unique and attractive look.

This is particularly useful in commercial settings, where aesthetics are important in creating a welcoming and professional atmosphere.

Where Epoxy Over Self-Leveling Concrete is Used ?

Epoxy over self-leveling concrete is useful in a variety of settings, including industrial warehouses, commercial kitchens, hospitals, schools, and residential garages.

These environments require a durable and easy-to-maintain flooring system that can withstand heavy foot traffic, spills, and other types of wear and tear.

Epoxy over self-leveling concrete provides a reliable and long-lasting solution to these needs.

Will Epoxy Hide Imperfections?

While epoxy can provide a smooth, seamless surface that can hide some imperfections in the underlying concrete, it is not a miracle solution for all types of damage or deterioration.

For example, epoxy may not be able to hide cracks or other structural defects in the concrete substrate. It is important to properly prepare the surface before applying the epoxy coating to ensure that the final result is even and uniform.

Why Is My Epoxy Not Self-Leveling?

There are several possible reasons why an epoxy coating may not self-level properly:

  • Incorrect mixing ratios: If the epoxy resin and hardener are not mixed in the correct proportions, the coating may not cure properly or may not self-level as expected.
  • Low temperature: Epoxy coatings require a certain temperature range for proper curing and self-leveling. If the temperature is too low, the epoxy may not flow evenly across the surface.
  • Poor surface preparation: If the self-leveling concrete surface is not properly cleaned or primed before applying the epoxy coating, the epoxy may not adhere properly or may not self-level as expected.
  • Uneven substrate: If the underlying self-leveling concrete substrate is not level or is uneven in some areas, the epoxy coating may not self-level properly in those areas.
