Comprehensive Guide to Concrete Resurfacing

Concrete resurfacing is a process that involves applying a new concrete on top of an existing concrete surface to improve its appearance, functionality, and durability. Commonly resurfaced concrete surfaces include driveways, patios, walkways, garage floors, and pool decks.

In this article we will tell you what to look for to know that it is resurface your old concrete with a new surface. We will also go over the resurfacing process and materials needed so you will be ready for your concrete resurfacing project!

Signs You Need to Resurface Your Concrete

Any old concrete can start to show signs of aging. Usually, concrete has a lifespan of 25-30 years, but there are factors that can speed up or slow down that process. Regardless of how long you have had your concrete, or what you use your concrete for, there will be tell-tale signs that signal you are ready for some concrete repair:

• Cracks and Spalling: These are common signs of wear and tear, particularly in older concrete surfaces. Cracks can be caused by the freeze thaw cycle - when concrete absorbs water and the water freezes, the concrete expands. Be sure to check your concrete driveways and walkways, as these areas tend to show their ages the fastest!
  Usually minor cracks can be fixed with a concrete sealer, but if your concrete surface has multiple deep cracks that is when it is time to resurface your concrete.

• Discoloration: Fading or staining can diminish the aesthetic appeal of your concrete floor. For this tell tale sign, you will want to keep an eye on places like concrete patios and walkways - any concrete surface that you have used colored or tinted concrete. The sun’s UV rays can make that color fade over time.
  Homeowners should check on their concrete driveways, especially in the areas where they park their cars most often. These spots are most likely to be stained, especially with oil or gas leaks.

• Uneven Surfaces: Unevenness can be a tripping hazard and affect the overall look of your property. This is common when there are large trees nearby that have roots growing under your concrete surface. The roots’ movement can push the concrete up from its usual flat surface.

Benefits of Concrete Resurfacing

• Cost-Effective: Resurfacing is often more affordable than replacing the entire concrete surface.
• Enhanced Curb Appeal: A fresh, resurfaced concrete surface can significantly improve your property's appearance. You can even choose to add some color to your concrete at the same time you resurface using concrete stains or even creating a stamped concrete pattern.
• Increased Durability: A properly resurfaced concrete surface can withstand heavy foot traffic and harsh weather conditions. The new concrete surface means that its lifespan extends by a couple decades too!

Step-by-Step Guide to Resurfacing Concrete

Now that you have a good understanding of how resurfacing can benefit your concrete surface, let’s go over the steps for your concrete resurfacing project.

1. Prepare the Surface

• Clean Thoroughly: Remove any dirt, debris, grease, or old coatings from the concrete surface. Then, use a pressure washer or a combination of soap or detergent and water to clean the surface well.
• Repair Damage: Fill in any cracks or holes with a concrete patching compound. Make sure you let the repairs cure completely before moving on to the next step.

2. Choose the Right Resurfacing Product

Be sure to carefully consider which type of resurfacing product you want to use. Some are known for exceptional durability, while others are more decorative. In some cases, a resurfacing product may only cover minor cracks, while others can level out uneven concrete surfaces!

• Concrete Resurfacer: This is a popular choice for adding a new layer of concrete to your existing surface. It is available in various thicknesses and can be used to level uneven surfaces. Concrete resurfacer can also be used to create decorative patterns like stamped concrete!
• Self-Leveling Compound: This product is ideal for smoothing out minor imperfections and creating a level surface. This compound is easy to apply and self-levels to a smooth finish. This might be a doable diy project for the motivated homeowners out there!
• Epoxy Coatings: Epoxy coatings are highly durable and resistant to chemicals. These are ideal for garage floors and industrial applications where you might find those types of concrete-staining chemicals.
• Polymer-Modified Concrete Overlay: This product is a popular choice for repairing damaged concrete. It is known for adding a new, durable surface that will stand up to the freeze thaw cycle, scratches, water and more!
• Microtopping: A thin, decorative concrete overlay that can be used to create a variety of finishes, including smooth, textured, or stamped concrete.

3. Mix the Concrete Resurfacer

For whatever concrete resurfacer product you decided on, be sure to follow the manufacturer's instructions for mixing the resurfacer. Try to get the right consistency, which should be thick enough to stick to the surface but also thin enough to spread easily.

4. Apply the Resurfacer

Use a trowel or squeegee to spread the concrete resurfacer evenly over the prepared surface. Not to put too much pressure on you, but you will need to work quickly because the material will be drying in real time. For textured finishes, use a broom or a textured roller to create the desired effect.

5. Cure the Resurfaced Concrete

Again, this step will depend on which type of concrete resurfacer you used. Allow the resurfaced concrete to cure properly according to the manufacturer's instructions. Keep the surface moist to prevent premature drying and cracking. There are several ways to do this, one example is watering your concrete for about a week every few hours.

Common Mistakes to Avoid When Resurfacing Concrete

Let’s go over some common mistakes so that you do not have to go through them! Here are a few ways that a concrete resurfacing project can go wrong:

• Inadequate Surface Preparation: If you do not thoroughly clean and prepare the surface it can cause problems with the concrete adhering to the surface. If the concrete resurfacer cannot stick then it does not work.
• Using the Wrong Product: Make sure you choose the right product for your needs - all concrete resurfacers are not alike. Choose a product that is suitable for your specific project and the condition of your concrete. Think about the thickness, durability, and aesthetics you want and choose accordingly.
• Incorrect Application: Applying the concrete resurfacer too thinly or unevenly can affect the final result. Be sure to check the manufacturer’s instructions for the product you choose and follow them carefully regarding how thickly to pour on the product.
• Skipping the Curing Process: Proper curing is essential for the durability of the resurfaced concrete. Without this step, concrete can crack more easily and will not be as durable. Also, the concrete surface can end up being more porous, soaking up more water - making the freeze thaw cycle even more damaging.

Cost of Concrete Resurfacing

The cost of resurfacing concrete can vary depending on several factors, including how many square feet the area is, the type of product used, and labor costs. DIY resurfacing can be a cost-effective option, but hiring a professional contractor may be better - or even necessary! - for larger or more complex projects. It mat be worth it to weight the pros and cons of replacing your concrete based on overall concrete costs.

Maintenance Tips for Resurfaced Concrete

• Regular Cleaning: Clean your resurfaced concrete regularly to remove dirt and debris.
• Sealing: Apply a concrete sealer to protect the surface from stains, water damage, and UV rays.
• Minor Repairs: Address minor cracks or chips as soon as you see them to prevent further damage.

By following these guidelines and addressing common concerns, you can successfully resurface your concrete surfaces and improve the overall functionality and curb appeal of your property!
