Your garage floor might be showing signs of wear and tear like cracks, stains, and uneven surfaces can make your once-pristine garage look neglected. Thankfully, resurfacing your concrete garage floor is a DIY project that can dramatically improve both the appearance and durability of the space. Whether you’re looking to tackle it as a weekend project or hire a professional, this guide walks you through everything you need to know for successful concrete garage floor resurfacing.
Why Resurface Your Concrete Garage Floor?
Before diving into the steps, it’s important to understand why you should consider resurfacing your garage floor. Concrete floors are durable, but they are not immune to damage. Over time, exposure to moisture, vehicle traffic, oil spills, and harsh weather conditions can cause cracks and surface degradation. Resurfacing your concrete floor not only improves its appearance but also increases its lifespan, prevents further damage, and adds value to your home.
Materials You Will Need
Before you start, gather all the materials and tools that you will need for the garage floor resurfacing. This will save you time and frustration later on:
- Concrete resurfacing compound (specific for garage floors)
- Concrete cleaner or degreaser
- Pressure washer or hose
- Scrub brush and mop
- Painter’s tape (optional)
- Large bucket for mixing
- Trowel or squeegee
- Power sander (if there are high spots)
- Concrete patching compound (for deeper cracks)
- Protective gloves, safety glasses, and a dust mask
Step 1: Clean the Concrete Surface
The first and most crucial step in resurfacing your concrete garage floor is thorough cleaning. The surface must be free of dirt, oil, grease, and other contaminants to ensure the resurfacing compound adheres properly.
Start by sweeping the floor to remove debris. Next, use a concrete cleaner or degreaser to scrub away any stubborn stains or grease marks. A pressure washer or hose with a high-pressure nozzle can be particularly helpful in flushing out dirt from the pores of the concrete.
Once you've cleaned the floor, let it dry completely before moving on to the next step. If there are any oil stains, consider using a degreaser or a concrete oil stain remover to get rid of them.
Step 2: Repair Cracks and Potholes
If your space has deep cracks, potholes, or chips, you will need to repair them before garage floor resurfacing. Using a concrete patching compound, fill in the cracks with a trowel. For larger holes, you may need a bit more compound and extra time to smooth it out.
Allow the patching material to dry according to the manufacturer’s instructions. Once it's set, lightly sand the patched areas to level them with the surrounding floor.
Step 3: Etch the Concrete Surface
To ensure the garage floor resurfacing compound bonds well with the concrete, you’ll need to etch the surface. This can be done with an etching solution, which is typically a mix of muriatic acid and water. Always wear protective gloves, goggles, and a mask when handling etching solutions.
Apply the etching solution generously to the concrete floor and scrub it with a stiff brush to help open up the pores. Once the floor has been etched, rinse it thoroughly with water and allow it to dry completely. If you used a power washer, this step should be easy, as it will help remove any residue from the etching solution.
Step 4: Mix the Resurfacing Compound
Concrete resurfacing compounds are often in powder form, and you will need to mix them with water before applying them to your floor. Always follow the manufacturer’s instructions for the exact ratio of compound to water, as too much or too little water can affect the finish.
Mix the compound in a large bucket until it has a smooth, pourable consistency. It is best to mix in small batches as the compound can dry quickly, depending on the temperature and humidity. This will keep the garage floor resurfacing process running smoothly.
Step 5: Apply the Resurfacing Compound
Now for the fun part: applying the resurfacing compound! Start in one corner of the garage and work your way out to avoid getting trapped in a corner. Use a trowel or squeegee to spread the compound evenly across the floor, making sure it fills any low spots and smooths over the surface.
Work quickly but carefully, as the compound can begin to set in as little as 10-15 minutes. If necessary, go over the surface a second time to ensure complete coverage. For best results, apply the resurfacing compound in sections, overlapping each area slightly to avoid seams.
Step 6: Smooth and Level the Surface
After applying the resurfacing compound, use a trowel to smooth out any imperfections or uneven areas. Be sure to level out the compound to create an even surface. If you notice any large bubbles or imperfections, smooth them out gently with the edge of the trowel.
If the area is large for garage floor resurfacing, you may want to use a long-handled squeegee to spread the compound more efficiently.
Step 7: Allow Time to Dry
Once the resurfacing compound has been applied, it’s time to let it cure. This typically takes about 24 hours, depending on the weather conditions. Avoid walking on the floor during this time, and do not drive or park vehicles on it for at least 72 hours.
If you live in an area with high humidity or rainy conditions, consider using a fan or dehumidifier to speed up the drying process.
