Concrete Patio Resurfacing & Repair

SUNDEK has been resurfacing concrete patios for almost 50 years.

Why resurface a concrete patio?

If your patio surface is uneven or has stains, cracks, or other damage, resurfacing it is often the best solution. You can also resurface your patio to upgrade its design. SUNDEK has a variety of colors, textures, and patterns to choose from.

About cracks in concrete surfaces

If your existing patio has cracks, you need to make sure they’re filled before resurfacing. It’s also important to understand why the cracks appeared so that you can address any issues. Cracks arise for a variety of reasons. Here are some possibilities:

Decorative Concrete Patio

  • Improper installation
  • Problems with the concrete mix
  • Freeze/thaw damage
  • Soil that was poorly compacted before the concrete installation
  • Roots from a nearby tree

Your local SUNDEK contractor can help you figure out the best way to resolve cracks, if necessary.

About uneven concrete surfaces

Even if you have a concrete patio that’s not level, SUNDEK can resurface it. We will apply a thicker coating wherever needed to make the surface even. The result will be a patio without trip hazards or spots where water puddles.

Concrete Overlayed Patio

Frequently asked questions

What is concrete resurfacing?

Concrete resurfacing begins with an existing concrete surface. After preparing the surface, a concrete overlay (also called a concrete coating) is applied to the existing concrete. See some of the colors, textures, and masonry effects that can be added.

Does concrete resurfacing last?

A concrete overlay will last for many years when its correctly applied and protected by a sealer, even if there’s heavy foot traffic. By keeping up with maintenance and reapplying sealer, you can keep your patio looking fresh longer.

How much does it cost to resurface a patio?

Costs vary by region, and the current state of your concrete patio. When working with one of our dealers, you’ll receive a customized quote based on a price per square foot. Contact your local dealer to get an estimate.

Resurfacing your patio is less expensive than ripping out and replacing your concrete surface. It’s also less messy and time consuming. SUNDEK can resurface a patio in just a few days.

Is it possible to resurface stamped concrete?

Yes, SUNDEK can apply a concrete coating over a stamped concrete surface. Additionally, we can create a stamped concrete overlay over any existing concrete surface.

Can you epoxy a concrete patio?

Epoxy flooring is typically used for commercial spaces and garages, but you can also apply it to patios. Contact your local SUNDEK authorized installer to find out if epoxy is right for your patio.

Designing your concrete patio

When spending time outside, people tend to gravitate toward the patio. So make yours picture-perfect and slip-resistant, too! SUNDEK offers a variety of design options. You can choose from many colors, textures, and masonry effects. 

To create a cohesive look, you can also apply a decorative concrete overlay to surrounding walls, fire pits, countertops, and fireplace surrounds. Talk with your local SUNDEK installer about options available. We pride ourselves in our customer service, and are here to guide you through the whole process. 

Resurfaced Patio with Pool Deck

Why resurfacing is better than installing pavers over your concrete surface.

Pavers can easily become uneven, causing tripping hazards and spots for water to puddle and weeds to grow through. Also, hiring a professional to lay pavers is expensive.

If you like the look of pavers, SUNDEK can create the same look. We can mimic the look of bricks, wood, flagstone, slate, brick, granite, and more. We can also seal the surface for protection from stains and UV damage.

Resurafed Patio

Why resurfacing is better than painting your concrete surface.

Painting your concrete surface is no simple task. Concrete is porous, so paint tends to peel. Using water-based stains, concrete dyes, or tinted sealers is a possibility, but some color variation is likely to occur.

SUNDEK can apply a concrete coating to your current surface with color already mixed in. We have a variety of colors to choose from. We can also seal the surface for protection from stains, UV damage, and other elements.

Installation of a SUNDEK patio coating

Here’s an overview of the installation process (details vary depending on which products are used):

  • Prepare & Repair. Etch, grind, or shot blast the concrete surface to make it porous. Fix cracks or other existing damage.
  • Clean & Prime. Pressure wash and let surface thoroughly dry. Apply primer if necessary.
  • Mix Product. Following instructions, mix the product to prepare it for application. Mix in color if necessary.
  • Apply overlay. Depending on the desired look, apply the overlay by spraying, rolling, or troweling.
  • Add Patterns & Texture. This is completed using hand-trowels, rakes, stamps and other specialty tools.
  • Cure & Seal. After the overlay cures, add a sealer for additional protection. Customers often ask us if a concrete patio needs to be sealed, and our answer is always yes. A sealer will preserve the look of your patio for longer. It also enhances its stain resistance and makes it easier to maintain. Read more about why you should seal your concrete patio.

The best way to lengthen the lifespan of your patio is to invest in a sealer. Keep in mind that even high-quality sealers need to be reapplied (reapplying a sealer is less expensive than having to get your patio resurfaced again). Talk to your SUNDEK dealer about how often you’ll need to reseal your surface.

Aside from applying a sealer, maintenance includes using an ordinary broom or mop to remove dust, grass clippings, or other debris every few weeks. You can simply spray off the surface with a hose to resolve any dirty spots. If you live in a location with harsh winter weather, it’s important to protect your patio during freezing temperatures.

Although several of our top coatings are chemical and moisture resistant, we recommend that you clean chemical spills as quickly as possible. For stubborn spots, you can use commercial cleaners, but they need to be non-abrasive and formulated for the surface. You can also use a pressure washer if necessary.
