From a compatibility perspective, the answer is yes, it is possible to do so. However, several factors should be considered to ensure a successful application.
Surface Preparation
The key to achieving a good bond between the concrete bonding adhesive and the epoxy coating lies in proper surface preparation. The surface must be clean, dry, and free from any contaminants such as grease, oil, or loose debris. Abrasive methods like shot blasting or diamond grinding are often used to mechanically prepare the surface and promote adhesion.
Priming
After the concrete bonding adhesive has been applied and allowed to dry according to the manufacturer’s instructions, it is recommended to apply a primer specifically formulated for epoxy coatings. This step will further enhance the adhesion, ensuring a solid bond between the adhesive and the epoxy layer.
Choosing the Right Epoxy System
When selecting an epoxy coating, it is essential to choose a system that is compatible with the concrete bonding adhesive. Some epoxy formulations are explicitly designed to work over primers or bonding agents, while others may not provide the desired adhesion. Consult with the manufacturer or a knowledgeable professional to determine the most suitable epoxy system for your specific application.
Application Procedure
Once the surface has been prepped and primed, the epoxy coating can be applied following the manufacturer’s instructions. It is crucial to apply the coating uniformly, avoiding puddling or excessive build-up in certain areas. Proper curing time should be allowed to ensure the epoxy fully sets and develops its desired properties.
It is possible to apply an epoxy coating on top of a concrete bonding adhesive, provided that proper surface preparation, priming, and selection of a compatible epoxy system are done. Following the recommended application procedure will ensure a strong and durable bond, resulting in an enhanced concrete surface that is both functional and visually appealing.
