    Big project may just want to remove loose/peeling areas then clean and repaint.....Epoxy is a strong adhesive or paint that was developed to withstand wear and tear. Because it is so strong, it can be very difficult to remove. Removing this product requires careful planning, consideration, preparation, and patience. Because the product is resistant to traditional paint removal methods, very strong chemical solutions then scraping or high-pressure abrasive tools must be used to remove epoxy paint. When removing epoxy paint, make sure you consider your removal options carefully and take the necessary safety measures.

    • Opt for a methylene chloride stripper. Since epoxy paint is strong and resistant to wear and tear, removing it with a typical paint thinner will not work. Working with a stripper that contains methylene chloride, also called dichloromethane, will work best for removing epoxy paint. [ These can be found at home improvement stores, industrial suppliers, and various online retailers.Methylene chloride is a carcinogen and can cause respiratory, eye, and skin irritations. In addition, exposure to high concentrations can cause dizziness, confusion, headache, nausea, and even unconsciousness and death.
    • It is important to follow the safety measures and instructions provided with the product.

    Consider using a caustic stripper. Caustic strippers are also an effective option for removing epoxy paint. These products work to break down the chemicals in the paint. They typically take longer to remove paint than methylene chloride strippers, but they carry fewer health risks. If the surface you are working with has several, thick layers of epoxy paint, consider using a caustic stripper.

    • Caustic strippers should not be used to remove epoxy paint on wood since they can break down the fibers in the wood and attract moisture.

    Wash the surface area. After you have removed the paint, wipe the surface area with a damp washcloth or towel to neutralize the pH balance. Caustic strippers can be cleaned with vinegar and water, while others can be cleaned with mineral spirits. If you used a methylene chloride stripper, use mineral spirits to clean the surface as water can damage the surface of wood.wear protective boots,gloves,eye wear,respirator. Use strong fans,open up area for maximum air flow figure out where to throw all scrapings when done.

    You'll definitely want to use some kind of stripper (deglosser) and/or liquid sandpaper. You can take pictures and show them to the people at your local hardware store and they should also be able to guide you in the right direction.
