Concrete is everywhere – driveways, sidewalks, patios, and floors. Over time, it can become cracked, pitted, or just plain ugly. So, can you resurface bad concrete? Yes, you can! This article will explain how to do it, why it’s a cost-effective solution, and the steps involved. We’ll also answer some common questions to help you make an informed decision. Let’s dive in and see how you can give your concrete a fresh, new look without breaking the bank.
What Is Concrete Resurfacing?
Concrete resurfacing is a method used to repair and rejuvenate old, damaged concrete surfaces. Instead of tearing out the existing concrete and starting from scratch, a new layer of concrete or a special resurfacing compound is applied over the old surface. This process can fix cracks, pits, and other imperfections, giving the concrete a brand-new appearance.
Why Should You Consider Resurfacing Concrete?
Saves Money
Resurfacing concrete is much cheaper than replacing it entirely. You save on labor, materials, and disposal costs. Plus, it takes less time, which means lower costs overall.
Improves Appearance
A fresh layer can make old, worn-out concrete look new again. You can even add colors and patterns to enhance its appearance.
Extends Lifespan
Resurfacing adds a protective layer to the concrete, making it more durable and resistant to wear and tear.
Eco-Friendly
By reusing the existing concrete, you reduce waste and the need for new materials. This makes resurfacing a more environmentally friendly option.
How Do You Resurface Bad Concrete?
Step 1: Clean the Surface
Before you start, the concrete surface must be clean. Remove any dirt, debris, grease, or oil stains. A power washer can be very effective for this step.
Step 2: Repair Major Damage
Fill in large cracks and pits with a concrete repair mix. This ensures a smooth, even surface for the new layer.
Step 3: Prepare the Resurfacing Mix
Follow the manufacturer’s instructions to mix the resurfacing compound. It should have a consistent, spreadable texture.
Step 4: Apply the Resurfacing Layer
Use a trowel or squeegee to spread the mix evenly over the concrete. Work in small sections to ensure even coverage and avoid the mix drying out before you spread it.
Step 5: Finish the Surface
Once applied, you can add texture to the surface if desired. Use a broom or a special texture roller for this. Allow the surface to dry according to the manufacturer’s instructions.
What Are the Best Conditions for Resurfacing Concrete?
Concrete resurfacing works best in mild, dry weather. Avoid extremely hot or cold temperatures and ensure there’s no rain in the forecast for at least 24 hours after application. Ideal temperatures range between 50°F and 80°F.
Can You Resurface Concrete Yourself?
Yes, you can resurface concrete yourself if you’re handy and have the right tools. However, for large areas or if you’re not confident in your DIY skills, hiring a professional is a good idea. They have the experience and equipment to do the job quickly and efficiently.
What Are the Common Mistakes to Avoid When Resurfacing Concrete?
Skipping Surface Preparation
Improper preparation can lead to poor adhesion and a short lifespan for the new surface.
Incorrect Mixing
Follow the manufacturer’s instructions carefully when mixing the resurfacing compound. Too much or too little water can affect the strength and durability of the new surface.
Poor Application Technique
Apply the resurfacing compound evenly. Uneven application can lead to an unattractive finish and weak spots.
Ignoring Weather Conditions
Resurfacing in bad weather can lead to premature drying or moisture issues, which can compromise the integrity of the new surface.
How Long Does Resurfaced Concrete Last?
Resurfaced concrete can last 8-15 years if properly applied and maintained. Regular cleaning and sealing can extend its lifespan even further.
Can You Add Color to Resurfaced Concrete?
Yes, you can add color to the resurfacing mix or apply a concrete stain after the surface has cured. This allows you to customize the look of your concrete to match your style and preferences.
What Are the Alternatives to Resurfacing Concrete?
Concrete Overlay
A concrete overlay is a thin layer of new concrete applied over the old surface. It can be stamped, stained, or textured to create a new look.
Epoxy Coatings
Epoxy coatings are durable and come in various colors and finishes. They’re great for garage floors and commercial spaces.
Polyurethane Coatings
Polyurethane coatings offer high durability and resistance to chemicals. They’re often used in industrial settings.
Is Resurfacing Concrete Environmentally Friendly?
Yes, resurfacing concrete is an environmentally friendly option. It reduces waste by reusing the existing concrete and minimizes the need for new materials. Additionally, it often uses less energy and resources compared to full replacement.
How Do You Maintain Resurfaced Concrete?
Regular Cleaning
Keep the surface clean by sweeping and washing it regularly to remove dirt and debris.
Sealing
Apply a concrete sealer to protect the surface from stains, moisture, and wear. Reapply the sealer every 1-2 years, depending on the level of use.
Avoid Heavy Impacts
Prevent heavy objects from dropping on the resurfaced concrete to avoid cracks and damage.
What Are the Signs That Concrete Needs Resurfacing?
Visible Cracks and Pits
If your concrete has visible cracks and pits, it might be time to resurface.
Discoloration
Stains and discoloration that can’t be cleaned away are another sign.
Uneven Surface
An uneven surface can be hazardous and is a good reason to consider resurfacing.
How Much Does Concrete Resurfacing Cost?
The cost of concrete resurfacing varies depending on the area size, the condition of the concrete, and the materials used. On average, you can expect to pay between $3 to $10 per square foot.
Can You Resurface All Types of Concrete?
Most types of concrete surfaces can be resurfaced, including driveways, patios, sidewalks, and interior floors. However, if the concrete is severely damaged or structurally unsound, resurfacing may not be a viable option.
FAQs
1. Can you resurface concrete in cold weather?
- It’s best to avoid resurfacing in temperatures below 50°F as the mix may not cure properly.
2. How long does it take for resurfaced concrete to dry?
- It typically takes 24-48 hours for the resurfacing compound to dry, but full curing can take up to a week.
3. Can you resurface a concrete driveway?
- Yes, driveways are one of the most common surfaces to resurface.
4. What tools do I need for concrete resurfacing?
- You’ll need a power washer, trowel or squeegee, mixing bucket, and a broom or texture roller.
5. Is resurfacing concrete a permanent solution?
- While not permanent, it can extend the life of your concrete by many years.
6. Can you resurface stamped concrete?
- Yes, but it’s essential to follow specific steps to maintain the stamped pattern.
7. Does resurfacing work on heavily damaged concrete?
- It depends. Small cracks and pits can be fixed, but severely damaged concrete may need replacement.
8. What are the benefits of sealing resurfaced concrete?
- Sealing protects against stains, moisture, and wear, extending the surface’s lifespan.
9. Can you resurface concrete more than once?
- Yes, you can resurface concrete multiple times as long as the base is still sound.
