How to Prep and Recoat an Older Epoxy Floor for a New Coat

On August 31, 2022

An epoxy coating creates a durable, firm, and impermeable surface that is harder than concrete and wood substrate. However, like other flooring materials, epoxy doesn’t last forever.

The wear and tear from heavy foot traffic, vehicles, furniture, and lawnmowers can take a toll on an epoxy coating. If you have an epoxy garage floor that has seen better days and lost its shine, garage floor resurfacing or garage floor refinishing offers a cost-effective way to give your floor a new lease on life.

As long as the existing floor coating is a two-part resin product such as epoxy, polyurea, polyurethane, or polyaspartic, you can apply an additional coat of a compatible product with no issues. However, always consult the manufacturer of the new coating before beginning your project.

How you prep the surface determines the outcome. You must prepare the surface thoroughly so the new epoxy can adequately adhere to it. Keep reading to learn how to prep and recoat an older epoxy floor for a new coat.

How to Prep Epoxy for a Fresh Coat

The most critical part of prepping for a new coat is to rough up the surface of the older coat to create enough grip for the fresh coat to adhere to. You can achieve this in two ways:

  1. Use 120-grit sandpaper on an orbital or pole sander. Rather than remove the surface, you merely want to rough it up. After sanding, the floor should look deglossed.
  2. Rent a buffer with a 100-grit sanding screen. Buffers work faster than sanders, allowing you to cover larger floor spaces in less time.

After priming the surface, sweep up the dirt and debris, then thoroughly vacuum the entire floor with a shop vac.

Next, wipe the surface with a cleaning solution such as denatured alcohol on a microfiber mop or small towel. The denatured alcohol will remove all the fine dust particles, leaving the surface squeaky clean in preparation for the application process.

If you have an older coating that needs resurfacing, use a 60-80 grit sanding screen or 80-100 grit sandpaper. The sanding screen or sandpaper will eliminate any deep scratches or embedded dirt by removing a small layer of the coating.

The same treatment works well for a worn coating that has adhered well but has spots where the coating has worn through to the concrete slab. The more aggressive grit also preps the bare concrete.

Applying the Epoxy

After properly preparing the floor surface, follow these steps for a smooth epoxy application:

  • Mix your epoxy according to the manufacturer’s instructions, then pour it onto the surface in small stripes.
  • Next, use an appropriate floor roller to spread the epoxy mix evenly throughout the floor surface.
  • Once complete, give the garage floor epoxy ample time to cure before using the surface.

Can You Recoat Your Epoxy Floor?

Remember, you can’t recoat all epoxy surfaces.

Inspect the existing coat thoroughly to ensure all the epoxy is attached. Don’t recoat an extensively cracked, peeling, or bubbling finish. Such a damaged finish prevents the new finish from adhering properly.

You also want to look for areas where the epoxy has pulled away from the concrete surface and sections of severe unevenness or excessive wear. In such cases, you’ll want to use a shot blaster or floor grinder to remove the existing coating and lay a fresh coat of epoxy.
