Removing epoxy coatings from concrete is common practice in the epoxy flooring business. But although common, it never easy, and can often be a big gamble when estimating time and material.
Epoxy coating removal is a necessary step when polishing concrete, or when a failed coating needs to be removed. However, although saying “removing epoxy” is easy, the actual process is much more difficult.
The most important thing to look for when assessing a demo floor job, is how thick the existing coating is. Epoxy thickness is measured in mils. And the more mils of epoxy on the floors, the more difficult it will be to remove that epoxy.
But for reference, a 20-30 mils of epoxy is about as thick as a credit card. So if you’re able to remove some coating during your site visit, compare it to your credit card to determine how thick the existing floor is. But keep in mind that the floor temperature needs to be considered. So when visiting potential job opportunities, be sure to bring your industrial infrared thermometer to gauge the temperature for the floor.
