Transform Your Cracked Concrete: The Complete Guide to Installing Epoxy Flooring Over Existing Concrete Cracks
If you’ve been staring at unsightly cracks in your concrete floor and wondering whether you can simply install epoxy flooring over them, you’re not alone. This is one of the most common questions homeowners and business owners ask when considering a flooring upgrade. The good news is that with proper preparation and techniques, epoxy flooring can be successfully installed over existing concrete cracks, transforming your damaged surface into a beautiful, durable floor.
Understanding Why Concrete Cracks
Before diving into the installation process, it’s important to understand why concrete develops cracks in the first place. Concrete naturally cracks over time, and these cracks vary by type and severity. The curing process decreases the volume of the concrete mass due to the evaporation of water content and forces the concrete to develop cracks in the weaker parts of its construct. Concrete cracks are often caused by flexures, shrinkages, or defective materials, such as an incorrect amount of concrete in the mix or inadequate curing.
Common types of cracks include shrinkage cracks, settlement cracks, and hairline cracks. Most garage or basement floors develop some form of cracks due to the nature of concrete. They may be so small as to go unnoticed or the cracks may be “hidden” within the control joints.
Can You Install Epoxy Over Cracks? The Answer is Yes, But…
The short answer is yes, you can install epoxy flooring over existing concrete cracks, but it requires proper preparation. Can epoxy fill the cracks? Not directly. Cracks are prepped and filled with specialized repair materials before coating. In order to apply epoxy floor coatings properly, concrete must be inspected and any damages repaired, including cracks sealed. Taking this step will help the epoxy coating cure properly and not bubble or peel over time.
Simply applying epoxy over cracks without proper preparation is a recipe for failure. Preparation of your floors by filling all cracks before epoxy coating is a crucial step to the overall look of your completed project. Skipping this step can lead to cracked floors down the road, bubbles in your epoxy, or uneven flooring.
The Crack Repair Process
Professional epoxy installation begins with thorough crack assessment and repair. Before applying epoxy, polyurea-polyaspartic flooring, damaged concrete (hairline cracks, spalling, “pitting” and major cracks) must be repaired first. The repair method depends on the size and severity of the cracks.
Small Hairline Cracks
For minor hairline cracks, the repair process is relatively straightforward. Once the epoxy primer coat has been applied, small hairline concrete cracks (smaller than the width of dime) require a little elastomeric sealant and a quick scrape with a putty knife. These small repairs can often be handled with specialized epoxy crack fillers.
Larger Cracks
Bigger cracks require more substantial repair methods. It should be clear at this point that repairs to large cracks (cracks exceeding the width of a dime, large concrete indentations, broken concrete edges), are a very different animal. If you attempt to repair these problems with an elastomeric sealant alone, you’ll be back for repairs. These issues require the preparation and application of more complex repair mixtures.
