How to Resurface a Concrete Patio? (A Step-by-Step Guide)

Has the concrete patio outside your property lost its shine? Is the dull and cracked appearance making your property less appealing? If you’re facing this problem, this guide is for you. Today, we’ll learn how to resurface a concrete patio and make it aesthetically appealing and sturdy. The resurfacing process can turn it into a stunning and functional area, whether it’s cracked, stained, or general wear and tear.

Let’s get started.

How to Resurface a Concrete Patio?

Clean the Concrete

The first step to revamping your concrete patio is a thorough cleaning. You would need a pressure washer for this. But before using it, choose a 25-degree fan tip attachment and maintain a safe distance of 6-8 inches from the surface. This focused stream effectively removes dirt, grime, and stubborn rust stains.

As the water washes away years of buildup, look for loose or flaking concrete. These areas might require more TLC (or tender loving care). For minor issues, a wire brush or putty knife can help remove problematic patches. However, consider calling a professional for repairs if the damage is extensive or involves large, crumbling sections.

Repair/Fix Any Cracks in the Concrete

Once you have cleaned the concrete, it’s time to tackle any cracks, holes, or uneven surfaces.

After the concrete dries completely, select a patching material suitable for the size and depth of the imperfections. A pre-mixed concrete patching compound is user-friendly for minor cracks and shallow pits. Apply it with a trowel or putty knife, ensuring a smooth and level finish that matches the surrounding concrete as closely as possible.

You might need a cementitious patching material that requires mixing with water for larger or deeper gaps. Always follow the manufacturer’s instructions for proper mixing ratios and application techniques. Remember, a strong bond is essential, so ensure good adhesion between the patch and the existing concrete.

Use a Bonding Agent

This step is crucial for projects involving cement-based overlay materials like stamped concrete or micro-topping. It acts as a bridge, creating a stronger bond between the existing concrete and the new overlay.

After your patches have completely cured (refer to the manufacturer’s recommended drying time), it’s time to apply the bonding agent. Many of these products contain latex or polymers, which enhance the adhesive properties, ensuring the overlay adheres seamlessly to the concrete base.

There are several ways to apply the bonding agent, with rolling being the most common method. For optimal coverage, use a roller with a ⅜-inch nap. Remember to pay close attention to the manufacturer’s instructions. Some bonding agents require a specific tackiness before applying the overlay, so timing is key.

Mix the Materials

If applying a stamped overlay or micro-topping, carefully review the manufacturer’s instructions on the product packaging. This is crucial as the specific chemical makeup of the overlay material may dictate a limited working time before it hardens, making further adjustments difficult without causing damage or compromising its integrity.

The typical process involves:

 

• Emptying a bag of dry overlay mix into a seven-gallon bucket.
• Measure and add the specified amount of water.
• Potentially incorporating additional additives like liquid or powdered pigments for coloration.

 

Thorough mixing is essential, often achieved using a power drill equipped with a mixing paddle attachment. Adhere to the mixing guidelines provided on the packaging to avoid introducing air bubbles into the mixture. Trapped air can alter the chemical reaction and create voids within the overlay, potentially weakening the final product’s sturdiness.

Apply the Material

There are two options that you could use.

 

• Option 1: Cement Overlay

1. Prepare the base: Ensure your patio is clean and ready for the new layer.
2. Pour and spread: The cement mix is your star here. Pour it directly onto the patio and use a trowel for even distribution. Think thin layer, around ¼ to ⅜ inch thick.
3. Smooth finish: Work the surface to achieve a level and polished result.

 

• Option 2: Stain or Epoxy Paint

1. Read the manual: Each stain or paint has specific instructions. Follow them closely for the best outcome.
2. Roller or sprayer: Choose your application tool based on the product and your preference.
3. Watch the weather: Hot and windy conditions can dry the stain or paint quickly. Work in manageable sections to avoid unevenness, ensuring a seamless final look.

 

Important tip: Existing cracks or control joints in your patio may need attention. Whether you’re using an overlay or a coating, ensure these lines are continued through the new surface to prevent future cracking.

Apply the Finish to the Cement Overlay Material

The finishing process is delicate, as mistakes during this phase can leave permanent marks on the rapidly hardening cement surface. Accidental scratches from tools or debris, like leaves or sticks, falling onto the wet cement are common mishaps. You must know how to rectify these minor accidents, which tend to occur at the most inconvenient moments.

For those applying a cement overlay, this stage is where creativity comes into play. Stamping patterns into the cement or employing techniques like brooming or swirl troweling adds texture and visual appeal. These textures not only enhance the aesthetics but also improve safety by providing better traction. This stage demands experience and skill, so if you lack the necessary knowledge, it’s best to hire a professional. They can save you time and energy and ensure an amazing final result.

Apply the Sealer

After the cement overlay or stain/epoxy paint has fully cured, typically within 24-48 hours, it’s time to protect your hard work with a sealer. This critical step safeguards the new surface from stains, UV damage, and premature wear. Choose a sealer suitable for exterior concrete patios, such as an acrylic or polyurethane-based product. Read the manufacturer’s instructions carefully and follow the recommended application method – rolling, spraying, or using a squeegee.

Apply the sealer in thin, even coats, allowing each coat to dry completely before applying the next. Depending on the product and the desired level of protection, you may need two or three coats. During application, ensure adequate ventilation and wear protective gear like gloves and a respirator mask. Avoid applying the sealer in direct sunlight or extreme temperatures, as this can affect its performance.

Once the sealer has fully cured, typically within 24-48 hours, your resurfaced concrete patio is ready to withstand the elements and foot traffic, providing you with a beautiful and long-lasting outdoor living space.
