Concealing Cracked Concrete Patios: Creative Solutions For Homeowners

A cracked concrete patio is not only unsightly but can also be a trip hazard. Fortunately, there are several ways to hide and repair these cracks. For hairline cracks, a concrete stain or concrete paint can be used to camouflage the cracks. For deeper cracks, a concrete crack filler or concrete patching compound can be used to fill in the gaps before painting or resurfacing the patio. Alternatively, if you're looking for a more natural look, you can widen the cracks, fill them with soil, and plant ground cover seeds for a purposeful look.

Use a concrete crack filler

If you have a cracked concrete patio, you can use a concrete crack filler to repair it. This is a simple and relatively inexpensive DIY project. Here is a step-by-step guide on how to do it:

Prepare the Crack

Before applying the concrete crack filler, you need to prepare the crack. First, put on safety glasses and hearing protection. Then, use a heavy-duty flat mason's chisel and a hammer to widen the crack and create a V-shape. This will help the patch materials stick better. Tap the back of the chisel lightly with the hammer to force it about 1/4-inch into the crack, maintaining a width-to-depth ratio of 2:1. Continue to follow the crack as you tap, being careful not to chip out large sections of concrete.

Next, use a wire brush to vigorously brush the crack and dislodge any remaining small particles. Brush in the direction of the crack. Finally, use a shop vacuum to remove the smaller debris and dust.

Assess the Depth of the Crack

If the crack is deeper than 1/4-inch, you will need to fill it with a solid crack filler to bring it up to a 1/4-inch depth. You can use clean sand or a closed-cell backer rod. To use sand, dispense it by hand through a funnel, slowly adding small amounts at a time to control the height of the filler. For deeper cracks, use a 3/4-inch backer rod, forcing it into the crack with your fingers or a blunt tool such as a paint-stirring stick. Make sure the backer rod is firmly in place before proceeding to the next step.

Apply the Concrete Crack Filler

Now it's time to apply the concrete crack filler. First, cut off the end of the applicator tip and shake the container if necessary. Squirt a small amount of filler onto a piece of cardboard to ensure the consistency is correct. Then, force a bead of the filler into the crack, slowly drawing it along and ensuring it fully settles into the crack.

For high areas, use a putty knife to flatten the filler, drawing it in the direction of the crack. For low areas or pockets, add more filler and then trowel it down with the putty knife.

Let the patch material cure for at least 24 hours before use, painting, or surfacing.

Seal cracks with a caulk-based product

Sealing cracks with a caulk-based product is an effective way to hide a cracked concrete patio. This method is ideal for common hairline cracks that occur due to ground shifting, improper pouring conditions, or the nature of the concrete.

A flexible caulk-based product, such as Quikrete Concrete Repair, is recommended for this purpose. This acrylic-based caulk comes in a matte grey colour and has a textured finish designed to blend in with the surrounding concrete.

Before applying the caulk, it is important to prepare the crack to ensure the product adheres properly. Start by widening the crack with a heavy-duty flat mason's chisel and a hammer. Wear safety glasses and hearing protection during this step. Place the chisel into the crack at a 45-degree angle and tap the back of it lightly with the hammer to force it about 1/4 inch into the crack. Continue along the crack, maintaining a width-to-depth ratio of 2:1.

Once the crack has been widened, use a wire brush to dislodge any remaining small particles. Brush along the direction of the crack, and then use a shop vacuum to remove the smaller debris and dust.

After the crack is clean and prepared, it's time to apply the caulk. Cut off the end of the applicator tip and shake the container if necessary. Some crack fillers may need to be mixed, so be sure to follow the manufacturer's instructions. Squirt a small amount of filler onto a piece of cardboard and then force a bead of the filler into the crack, slowly drawing it along and ensuring it fully settles before moving on.

For flat areas that fill the crack from side to side, no additional tooling is needed. For high areas, use a putty knife or trowel to flatten the filler, drawing it in the direction of the crack. For low areas or pockets, add more filler and then trowel it down immediately.

Allow the caulk to cure for at least 24 hours before using the patio or performing any additional steps, such as painting or resurfacing.

Use concrete resurfacer

If you're looking to hide a cracked concrete patio, one option is to use a concrete resurfacer. This method will create a smooth, fresh surface by pouring a thin layer of concrete over the existing slab. Here's a step-by-step guide on how to do it:

First, assess the condition of your patio. If the cracks are hairline or less than 1/4-inch wide, you can proceed with resurfacing. However, if the cracks are deeper or wider, you may need to fill them before resurfacing. It's important to ensure that the underlying cause of the cracks, such as water collection or uneven ground, is addressed to prevent further damage.

Next, clean the patio thoroughly. Remove any debris, weeds, or grass from the cracks using a brush, chisel, or pressure washer. You can also use a concrete outdoor cleaning solution with a pressure washer to remove stains, mould, and dirt. Ensure the patio is completely dry before proceeding.

Now, it's time to mix your concrete resurfacer. Follow the manufacturer's instructions on the product you've chosen. In general, you'll want to mix the resurfacer with water to achieve a syrup-like consistency. Working in small sections, pour the mixture onto the patio and use a squeegee to spread it smoothly.

After a few minutes, it's time to add a non-slip texture to the surface. You can use a concrete broom or a push broom to create this texture. Simply drag the broom across the wet concrete in a consistent pattern.

Finally, allow the concrete resurfacer to cure completely. Follow the manufacturer's instructions for curing time, as it may vary depending on the product and environmental conditions. Once it's cured, your patio will have a fresh, uniform look, and the cracks will be hidden.

Keep in mind that while resurfacing can improve the appearance of your patio, it's important to address any underlying issues to prevent the cracks from reappearing. Proper maintenance, such as annual power washing and resealing the concrete every few years, can also help extend the life of your patio.

Cover the patio with pavers

Covering a cracked concrete patio with pavers is a great way to enhance the look of your outdoor space without breaking the bank. Concrete pavers come in a wide range of sizes, colours, and materials, offering endless design combinations. They are also a low-cost, DIY-friendly option that can be installed directly over your existing patio, saving you time and money.

Before installing pavers over your concrete patio, there are a few things to consider and prepare. Firstly, inspect your concrete for large cracks, dips, or rises. Minor hairline cracks are generally acceptable, but any significant cracks may require repair before proceeding. Ensure the slope of your patio meets or exceeds the Interlocking Concrete Pavement Institute (ICPI) standard of a 2% slope grade for proper water drainage. Check that the threshold, siding, or pillars around your concrete area can accommodate the thickness of the pavers. Finally, clean your concrete surface thoroughly to ensure proper adhesion.

Once your concrete patio is prepared, you can begin installing the pavers. This process typically involves the following steps:

• Install a patio paving stone border: Glue or mortar your chosen pavers to the outside perimeter of the concrete area. This provides a sturdy base for the rest of the pavers.
• Lay a geo filter fabric: Cover the concrete area with a geo filter fabric to retain joint sand and prevent it from settling through the paving stones.
• Spread a thin layer of sand: Apply a thin layer of sand over the filter fabric to create a smooth finish and reduce moisture transfer.
• Lay the patio pavers: Starting in a corner, lay the field pavers over the bedding layer, working your way towards the middle. Use the Click and Drop method to avoid disturbing the sand layer.
• Sweep in exterior joint sand: Spread polymeric sand evenly over the pavers and sweep it into the gaps with a broom. Remove excess sand and lightly mist the sand with water to activate the binders.

By following these steps, you can easily cover your cracked concrete patio with pavers, creating an attractive and functional outdoor living space.

Use concrete paint

If you're looking to hide a cracked concrete patio, one option is to use concrete paint. This method can help you achieve a fresh new appearance for your patio. Here's a step-by-step guide on how to do it:

Step 1: Clean and Prepare the Surface

Before painting, it's essential to clean the concrete patio thoroughly and remove any loose cement or debris. Power washing is an effective way to ensure the surface is clean and ready for painting. Make sure the patio is completely dry before moving on to the next step.

Step 2: Choose the Right Paint

Select a concrete paint that is specifically designed for outdoor use and can withstand temperature and moisture fluctuations. Consider the colour carefully—you can match it to your existing patio colour or choose a new shade to create a different look. Tinted cement paints are available in a wide range of colours.

Step 3: Fill the Cracks

Small cracks can be filled with a solid concrete stain or concrete crack filler before painting. Choose a filler that closely matches the colour of your patio to minimise its visibility. Allow the filler to cure completely according to the manufacturer's instructions before proceeding.

Step 4: Apply the Paint

Follow the instructions on your chosen concrete paint for proper application. Typically, you'll use a long-handled paint roller specifically designed for concrete paint or tinted cement. Work in sections, and spread the paint or tinted cement mixture by pulling it towards you or pushing it away from you. Avoid the back-and-forth rolling motion typically used for painting walls.

Step 5: Allow for Drying and Curing

Once you've finished painting, allow the concrete paint to dry and cure completely. Refer to the manufacturer's instructions for the recommended drying time. This may take several hours or even a full day, depending on the product and the weather conditions.

Maintenance and Care

To maintain the appearance of your painted concrete patio, it's important to take some preventative measures. Seal the cracks to protect them from freeze-thaw events, which can cause widening. Avoid using ice melt or de-icers on the patio, as these can potentially harm the concrete. Use a push-broom or a snow shovel without metal wear-strips to remove snow and ice.
