How to Resurface Garage Floor

Summary: Resurfacing your garage floor can help protect it from damage and make it look like new. To start the process, you’ll need to clean and prepare the existing surface by removing any debris or stains. Next, apply a concrete resurfacing product using a trowel or squeegee, spreading it evenly over the floor.

What Causes Garage Floors to Deteriorate?

Several factors can contribute to the deterioration of garage floors. First, cars are constantly coming and going, which can track dirt, oil, and other debris. Over time, this build-up can cause the concrete to crack and crumble. Weather can also play a role in the deterioration of garage floors. Extreme temperatures can cause the concrete to expand and contract, leading to cracks and other damage.

Second, if your garage is attached to your house, it may be subject to the same foundation problems that can plague any home. Third, shifting soil, settling, and other issues can cause cracks in the garage floor. These problems can be exacerbated if your garage is not properly sealed or insulated. Finally, even if your garage is in good repair, it may be old. Over time, concrete will degrade and become more susceptible to damage.

Step by Step How to Resurface Garage Floor

Step 1: Assess the Condition of the Garage Floor

Before starting the resurfacing process, carefully assess the condition of your garage floor:

  • Inspect the floor for cracks, chips, and other damage.
  • Check for signs of moisture or water seepage.
  • Identify areas with grease or oil stains that need to be cleaned.

Step 2: Choose the Appropriate Resurfacing Material

Based on the condition of your garage floor, choose the appropriate resurfacing material:

  • For minor cracks and damage, use a concrete resurfacer or patching compound.
  • For extensive damage or uneven surfaces, consider using a self-leveling concrete overlay.
  • For a more decorative finish, opt for an epoxy or polyaspartic coating system.

Step 3: Prepare the Garage

Before resurfacing the garage floor, prepare the area by following these steps:

  • Remove all items and vehicles from the garage.
  • Clean the floor thoroughly using a broom and a wet-dry vacuum.
  • Use a degreaser or a commercial garage floor cleaner to remove oil and grease stains.
  • Repair cracks, holes, or other damage with a concrete patching compound, following the manufacturer’s instructions.

Step 4: Prepare the Concrete Surface

For the resurfacing material to adhere properly, the concrete surface must be clean and rough:

  • Use a pressure washer to clean the surface and remove dirt, dust, and debris.
  • Apply a concrete etching solution to roughen the surface and ensure better adhesion of the resurfacing material. Follow the manufacturer’s instructions for application and rinsing.
  • Allow the floor to dry completely before proceeding. This may take 24 to 48 hours, depending on the weather and humidity.

Step 5: Mix the Resurfacing Material

Following the manufacturer’s instructions, mix the resurfacing material:

  • For concrete resurfacer or self-leveling overlay, mix the dry powder with water in a clean container, using a drill with a mixing paddle attachment.
  • For epoxy or polyaspartic coatings, mix the two components (resin and hardener) in the specified proportions.

Step 6: Apply the Resurfacing Material

Apply the resurfacing material to the prepared garage floor, following the manufacturer’s recommendations:

  • For concrete resurfacer or self-leveling overlay, pour the mixture onto the floor and spread it evenly using a long-handled squeegee or trowel. Work in small sections to ensure an even application.
  • For epoxy or polyaspartic coatings, use a roller or brush to apply the coating in thin, even layers. Start at the back of the garage and work your way towards the entrance, maintaining a wet edge to avoid visible seams.

Step 7: Add Texture or Decorative Elements (Optional)

If desired, add texture or decorative elements to the resurfacing material while it’s still wet:

  • For a slip-resistant surface, broadcast a fine layer of sand or specially designed anti-slip additive over the wet resurfacing material.
  • For decorative effects, such as color flakes or metallic pigments, scatter them evenly over the wet epoxy or polyaspartic coating.

Step 8: Apply a Topcoat or Sealer (Optional)

To protect and enhance the appearance of the resurfaced garage floor, apply a topcoat or sealer:

  • For concrete resurfacer or self-leveling overlay, apply a concrete sealer after the material has fully cured, following the manufacturer’s instructions.
  • For epoxy or polyaspartic coatings, apply a clear topcoat according to the product’s specifications, which may include additional layers for enhanced durability.

Step 9: Allow the Resurfacing Material to Cure

Allow the resurfacing material to cure fully before using the garage:

  • For concrete resurfacer or self-leveling overlay, follow the manufacturer’s recommended curing time, typically 24 to 48 hours, before allowing foot traffic.
  • For epoxy or polyaspartic coatings, allow the material to cure for at least 24 hours before walking on it and a minimum of 72 hours before driving or placing heavy items on the floor.

Step 10: Reinstall Garage Items

Once the resurfaced floor has fully cured, carefully move items back into the garage:

  • Inspect the floor for any issues or imperfections and address them as needed.
  • Replace shelving, workbenches, and other garage fixtures, taking care not to scratch or damage the new floor.
  • Organize your tools, equipment, and other items, ensuring they are properly stored and secured.

Step 11: Maintain the Resurfaced Garage Floor

To keep your resurfaced garage floor looking its best and prolong its lifespan, practice regular maintenance:

  • Sweep and clean the floor regularly to remove dirt, dust, and debris.
  • Clean spills and stains promptly using a mild detergent and water, followed by a thorough rinse.
  • Avoid dragging heavy items across the floor, which can cause scratches or gouges.
  • Periodically reapply a topcoat or sealer as needed to maintain the floor’s protective finish.

Step 12: Monitor the Floor for Signs of Wear or Damage

Regularly inspect your resurfaced garage floor for signs of wear or damage:

  • Check for cracks, chips, or peeling, which may indicate a problem with the resurfacing material or the underlying concrete.
  • Look for signs of moisture or water seepage, which can cause damage to the floor and promote the growth of mold and mildew.
  • Address any issues promptly to prevent further damage and maintain the integrity and appearance of the floor.

By following these steps, you can successfully resurface your garage floor and create a durable, attractive, and functional space. Regular maintenance and monitoring can help ensure the long-term performance and beauty of your resurfaced floor, providing you with a garage you can be proud of for years to come.

How Much Does It Cost to Resurface a Garage Floor?

The cost of resurfacing a garage floor depends on the size of the floor and the materials you use. Resurfacing products can range from $30 to $100 per gallon. Topcoats and sealers can also vary in price, depending on your product type. Generally, you can expect to spend between $200 and $600 to resurface a standard two-car garage floor.

Some Tips and Warnings on How to Resurface Garage Floor


  1. Patch any cracks or holes in the floor with a concrete patching compound. If you have large cracks or holes, you may need to use a concrete saw to cut away sections of the floor so that you can properly fill them in.
  2. Be sure to clean the floor thoroughly before you begin resurfacing. Any dirt, grease, or other debris will prevent the new surface from adhering properly.
  3. If your garage floor is very old and damaged, you may need to apply a concrete primer before resurfacing. This will help ensure that the new surface will adhere properly.
  4. When choosing a resurfacing product, be sure to select one that is designed for use on concrete floors.
  5. Be sure to wear proper safety gear, gloves, goggles, and a respirator, when working with chemicals.
  6. Apply the resurfacing material to the floor in thin, even layers. Be sure to follow the manufacturer’s instructions for drying times between coats.
  7. Once the resurfacing material is dry, you may need to apply a sealer to protect the new surface.


  1. Do not attempt to resurface your garage floor if it is structurally unsound. If the floor is cracked or otherwise damaged, it will need to be repaired before resurfacing.
  2. Never mix different products together. This could cause dangerous chemical reactions.
  3. Always ventilate the area when working with toxic chemicals.
