Removing epoxy from concrete surfaces can be a daunting task due to its strong adhesive properties and chemical resistance. Epoxy is built strong, and built to last! Its very strength comes from how difficult it is to peel away from any surface it's installed on. But, by following these steps, you can restore your concrete surface with minimal damage and effort.
Epoxy Resin Flooring on Concrete Removal Methods
Method 1: Chemically Remove Epoxy Resin
Chemical epoxy removers are formulated to break down the hardened epoxy, making it easier to scrape off. These aren't just specialized solutions made for epoxy resin though, even a common household chemical like acetone is effective.
Be careful, though - some resins have more chemical resistance than others and may require more solution.
- Choose the Right Remover: Select a high-quality epoxy remover that is suitable for concrete surfaces. Acetone should work fine on most applications, but only you know if you need something heavier duty.
- Apply the Remover: Follow the product instructions to apply the remover evenly across the epoxy surface.
- Wait and Scrape: Allow the remover to sit for the recommended time to soften the epoxy. Use a putty knife or scraper to remove the softened epoxy.
- Clean the Surface: After scraping, clean the surface thoroughly with a concrete cleaner to remove any residue.
Products to Consider: XPS Cleaners & Degreasers
Method 2: Soften & Remove Epoxy Resin with Heat
For some epoxy resin removals, solutions like industrial floor grinders or shot blasters may be overkill. If you're correcting a mistake on a DIY project or a small part of a larger flooring project, you may want to apply localized heat. The heat will soften the epoxy resin, which helps to break down its adhesion to the concrete. This will allow you to simply scrape the epoxy off.
- Safety First: Wear protective gear, including gloves and safety glasses, to protect against heat and debris.
- Apply Heat: Use a heat gun to apply heat evenly over the epoxy surface. Keep the heat gun moving to avoid burning the concrete.
- Scrape the Epoxy: Once the epoxy has softened, use a scraper to remove it from the concrete.
- Clean the Surface: After removal, clean the concrete to remove any leftover residue.
Tools to Consider: Heat Guns, Scrapers
Method 3: Mechanical Removal of Epoxy Resin Flooring
Mechanical methods involve using specialized grinders, scrapers or shot blasters to remove epoxy off concrete surfaces. This is often the most effective method for large areas or heavily bonded epoxy.
- Choose the Right Tool: Select from grinders, floor removal scrapers, or shot blasters based on the size and thickness of the epoxy.
- Prepare the Surface: Ensure the area is clear of debris and that you are wearing appropriate safety gear.
- Grind or Blast the Epoxy: Use the tool to mechanically remove the epoxy, starting with a lower setting and increasing as needed.
- Clean Up: After removal, clean the surface to remove dust and debris.

Common Difficulties During Removal
Removing epoxy with heat can present several challenges. Uneven heating can cause partial removal, leaving some areas still bonded to the concrete. Overheating may damage the concrete surface, leading to discoloration or even cracking.
It's essential to move the heat gun continuously and monitor the epoxy closely to avoid these issues. Additionally, working in well-ventilated areas is crucial to avoid inhaling fumes generated by heating the epoxy.
As always when working with chemicals capable of breaking down the epoxy resin polymers, work carefully and patiently. Wear gloves & glasses to prevent unnecessary exposure.
If you're going the mechanical route, work slowly. A grinder is a powerful tool and should be treated with respect. Consider gaining an epoxy resin certification to get truly comfortable with these machines.
