Removing Epoxy Coatings with a Ride-On Scraper

Removing epoxy from a foundation before grouting is essential for a clean and strong bond between the grout and the foundation. A ride-on scraper can be highly effective for removing tough epoxy layers, especially over larger areas. Here’s how you might approach the process with a ride-on scraper:

Steps to Remove Epoxy Coatings with a Ride-On Scraper

1. Select the Right Blade:

   • For epoxy removal, use a high-strength, sharp blade compatible with your ride-on scraper. Heavy-duty or carbide blades can handle the rigidity of epoxy coatings.

   • Ensure the blade is set at the correct angle to avoid damaging the foundation surface.

2. Prepare the Area:

   • Clear the area of any loose debris and ensure proper ventilation, especially if indoors.

   • Mark out sections to work on for efficient removal.

3. Operate the Ride-On Scraper:

   • Start in one corner and work methodically across the area. Keep steady control of the scraper to maintain even pressure on the epoxy layer.

   • Allow the scraper to do the work, avoiding excessive force that could damage the foundation surface underneath.

4. Remove Residual Epoxy:

   • For any remaining stubborn patches, a hand-held scraper or heat gun can help.

   • Alternatively, chemical epoxy removers may be necessary in spots where the scraper cannot reach, but ensure compatibility with your specific surface.

5. Clean and Prepare the Surface for Grouting:

   • Once the epoxy is removed, thoroughly clean the surface to remove any residue or dust.

   • Check for levelness and any imperfections that might affect grouting, and repair these as needed.
