Understanding Pitted Garage Floors
Before diving into the repair process, it’s important to understand what causes pitted garage floors. Pitting occurs when the surface of the concrete deteriorates, resulting in small holes and craters. This damage can be caused by a variety of factors such as exposure to the elements, heavy vehicle traffic, and improper surface preparation.

5 Authoritative Steps for How to Repair Pitted Concrete Garage Floor
Here are the 5 steps you need to take for how to repair pitted concrete garage floor:
Step 1: Assessing the Damage
The first step in repairing a pitted garage floor is to assess the extent of the damage. Thoroughly inspect the floor, looking for areas with pits, cracks, and spalling. Spalling refers to the separation and crumbling of the concrete surface, often caused by freeze-thaw cycles or the use of corrosive substances like road salts.
Step 2: Cleaning and Preparing the Surface
Before starting any repair work, it’s crucial to clean and prepare the surface of the garage floor. Remove any loose debris, dirt, and oil stains using a concrete cleaner and a stiff brush. Pay special attention to the pitted areas, ensuring they are free from loose material.
Step 3: Filling and Repairing Pits and Cracks
Once the surface is clean, it’s time to fill and repair the pits and cracks in the garage floor. There are several options available for this step, depending on the size and depth of the damage.
Option 1: Self-Leveling Concrete Compound
For smaller pits and cracks, a self-leveling concrete compound can be an effective solution. Follow the manufacturer’s instructions to mix and apply the compound, ensuring it fills the pits and cracks evenly. Use a trowel or a putty knife to smooth out the surface, removing any excess compound.
Option 2: Epoxy-Based Patching Compound
For larger pits and cracks, an epoxy-based patching compound is recommended. These compounds provide excellent adhesion and durability. Mix the epoxy compound according to the manufacturer’s instructions and apply it to the damaged areas using a trowel or putty knife. Smooth the surface and allow it to dry and cure completely before proceeding.
Step 4: Resurfacing the Garage Floor
Once the pits and cracks have been filled and repaired, it’s time to resurface the entire garage floor. This step will ensure a uniform and seamless finish, hiding any remaining imperfections and providing a durable and attractive surface.
Option 1: Self-Leveling Concrete
Self-leveling concrete is a popular choice for resurfacing garage floors. It is easy to apply and provides a smooth and level finish. Mix the self-leveling concrete according to the manufacturer’s instructions and pour it onto the garage floor. Use a trowel or a squeegee to spread the concrete evenly, working it into any remaining pits or low spots. Allow the self-leveling concrete to dry and cure completely before moving on to the next steps.
Option 2: Concrete Overlay
Another option for resurfacing a pitted garage floor is to apply a concrete overlay. This involves applying a thin layer of concrete over the existing surface, providing a fresh and uniform appearance. Before applying the overlay, ensure the surface is clean and free from any debris. Mix the concrete overlay according to the manufacturer’s instructions and apply it using a trowel or a concrete float. Smooth out the surface and allow it to cure completely.
Option 3: Polyaspartic Floor Coating
For a more durable and long-lasting finish, consider using a polyaspartic floor coating. This type of coating provides excellent resistance to chemicals, abrasion, and UV damage. It can be applied directly over the repaired and resurfaced garage floor, providing a high-gloss and professional-looking finish. Follow the manufacturer’s instructions for mixing and applying the polyaspartic coating, ensuring a smooth and even application.
Step 5: Finishing Touches and Maintenance
Once the resurfacing process is complete, it’s important to take some additional steps to ensure the longevity and durability of your repaired garage floor.
- Allow the resurfaced floor to cure fully before subjecting it to heavy use or placing any objects on it.
- Apply a concrete sealer to protect the surface from stains, moisture, and damage. Follow the manufacturer’s instructions for application.
- Regularly clean the surface using a mild detergent and warm water. Avoid using harsh chemicals or abrasive cleaners that can damage the sealer.
- Avoid dragging heavy objects or using sharp tools that can scratch or gouge the surface.
- Place protective mats or pads under heavy equipment or vehicles to prevent damage to the surface.
- Periodically inspect the surface for any signs of wear or damage. Address any issues promptly to prevent further deterioration.

FAQs About How to Repair Pitted Concrete Garage Floor
Can Pitted Concrete Be Repaired?
Yes, pitted concrete can be repaired. Pitting in concrete can occur due to various factors such as freeze-thaw cycles, chemical exposure, age and wear, and improper installation. The repair process for pitted concrete depends on the severity of the pits. For minor pitting, surface-level repairs can be done using a concrete patch. However, for deeper pits, resurfacing the concrete with a concrete overlay is recommended. The repair process involves cleaning the surface, priming it, mixing and applying the overlay, and allowing it to cure. Polymer-modified cement patches are ideal for repairing garage floors, while deeply pitted concrete may require cementitious patching materials like epoxy or polyurea.
Can Pitting Be Fixed?
Yes, pitted concrete can be repaired. The repair process depends on the severity of the pits. For minor pitting, surface-level repairs can be done using a concrete patching compound or epoxy to fill the pits and smooth out the surface. Deeper pits may require resurfacing with a concrete overlay. The repair process typically involves cleaning the surface, priming it, mixing and applying the repair material, and allowing it to cure. Different materials like polymer-modified cement patches or epoxy and polyurea may be used depending on the extent of the pitting. Hiring a professional may be necessary for more extensive damage.
Can You Epoxy Over a Pitted Garage Floor?
Yes, you can epoxy over a pitted garage floor. The severity of the pits will determine the repair process. For minor pitting, you can use a concrete patching compound or epoxy to fill the pits and create a smoother surface. Deeper pits may require resurfacing with a concrete overlay. The repair process involves cleaning the surface, priming it, applying the repair material, and allowing it to cure. Different materials like polymer-modified cement patches or epoxy and polyurea may be used depending on the extent of the pitting. Hiring a professional may be necessary for more extensive damage.
Why is My Garage Floor Pitting?
Your garage floor may be pitting due to various factors. Some common causes of pitting in garage floors include freeze-thaw cycles, chemical exposure, age and wear, and improper installation. Freeze-thaw cycles can cause the concrete to expand and contract, leading to pitting over time. Chemical exposure, such as from oil or other corrosive substances, can also degrade the concrete surface and cause pitting. Age and wear can weaken the concrete, making it more susceptible to pitting. Lastly, if the garage floor is not installed properly, it may be more prone to pitting.
What Causes Pitting in Garage Floor?
Concrete pitting in a garage floor can be caused by several factors, including freeze-thaw cycles, chemical exposure, age and wear, and improper installation. Freeze-thaw cycles occur when moisture penetrates the concrete, freezes, and expands, leading to cracking and pitting. Chemical exposure, such as the use of harsh cleaning agents or gasoline spills, can erode the concrete surface and create pits. Over time, the natural aging process and regular wear can also contribute to pitting. Additionally, improper installation techniques, such as inadequate concrete mix or improper finishing, can result in a weak surface that is prone to pitting.
