When planning to renovate your patio or deck, it is crucial to have the right tools to ensure the job is done correctly. Among the tools you might need are a concrete mixer or a hand-held mortar mixer, an angle grinder with a construction-level vacuum cleaner and head attachment, a bucket with a flat bottom, trowels, a concrete spatula, a broom, a level, a measuring tape, gloves, goggles, dust masks, and clothes that can get a little dirty.

Before starting any work, clearing the patio area of any debris, such as leaves, twigs, or other objects, is vital. Afterward, sweep the area thoroughly to ensure it is spotless and free of any obstructions.

Checking for cracks, holes, or other damage on the surface of your concrete patio or deck is essential before starting any renovation work. Repairing any damage will ensure that the new surface is smooth and even and prevent any further damage from occurring in the future.

If you have a deck with a surface coating, you may need to grind it off using a large grinder. It is crucial to wear a breathing mask and vacuum to avoid inhaling concrete dust during this process. After removing the coating, thoroughly wash the surface with a garden hose to remove any debris or dust. This ensures the new surface adheres appropriately and provides a clean foundation for further work.

Key points:

  1. Clear the patio area of any debris
  2.  Inspect the surface for cracks, holes, and damage
  3.  Grind off decking surface coating if necessary
  4.  Wear a breathing mask and use a vacuum during grinding
  5.  Wash the surface thoroughly after coating removal
Don’t need too complicated tools for this job.

Assess the Slope of the Patio

To properly assess the slope of the patio, you will need to use a level.

Place the level in various patio areas to determine where the slope is uneven. This will help you identify the specific areas that need to be leveled.

Take note of any significant slopes or dips in the patio surface, as these will require special attention during the leveling process.

Once you have identified the areas that need to be leveled, you can begin planning the following steps to ensure your patio is safe, functional, and aesthetically pleasing.

Apply Self-Leveling Compound, or if you need a slope regular compound that doesn’t level by itself.

When applying a self-leveling compound to your patio, it’s essential to follow the instructions provided by the manufacturer to ensure that the mixture is prepared correctly.

Start by mixing the compound according to the recommended ratios, using a mixing paddle to blend the powder and water until they form a smooth consistency. 

Next, pour the mixture onto the lowest areas of the patio, covering all the spots that need to be leveled. The compound should be spread evenly across the patio’s surface using a trowel. This will ensure it fills gaps and creates a smooth, level surface. 

It must work quickly when applying the compound, as it sets relatively fast. Overworking the mixture can cause air bubbles, leading to an uneven surface. You’ll also need to wear protective gear like gloves and a mask to avoid contact with the compound and prevent inhalation of particles. 

If you need a slight tilt to your deck:

  1. Use straight wood as “benches” on the sides.
  2. Set them so that they lower in the direction where you want the water to go. This same philosophy can be applied if you have drainage.
  3. Set “benches” on the side, use a low drainage point, and screed around the deck, pointing in that direction. This will ensure that any water on your deck is drained correctly away, preventing damage and prolonging the life of your outdoor space.

Key points:

  1. Follow the manufacturer’s instructions when applying self-leveling compound
  2. Mix compound according to recommended ratios for a smooth consistency
  3. Pour mixture onto the lowest areas of the patio and spread evenly with a trowel
  4. Work quickly to avoid air bubbles and wear protective gear
  5. Use straight wood to create a slight tilt for drainage on the deck

Allow the Self-Leveling Compound to Dry

After applying the self-leveling compound, it is essential to let it dry completely before proceeding to the next step. This will ensure that the surface is level and smooth. 

The drying time will depend on a few factors, such as the type of compound used, the thickness of the layer applied, and the temperature and humidity in the room. Typically, the compound can take a few hours to a full day to fully dry. 

To check if the compound is dry, gently touch the surface. It is ready for the next step if it feels complex and dry.

Alternatively, you can use a level to check the levelness of the surface. Place the level in different directions and see if it indicates any unevenness. If the surface is still not level, additional layers of self-leveling compound may be needed. 

Remember, it is crucial to wait for the self-leveling compound to dry completely before proceeding to the next step to ensure a smooth and level surface.

Key points:

  1. Let the self-leveling compound dry completely before proceeding to the next step.
  2. Drying time depends on compound type, layer thickness, temperature, and humidity.
  3. It can take a few hours to a full day for the compound to fully dry.
  4. To check if the compound is dry, touch the surface gently or use a level to check for levelness.
  5. Additional layers may be needed if the surface still needs to be level.

Finishing Touches

When working on a concrete project, focusing on the finishing touches is crucial to achieve a polished and long-lasting result. To begin with, inspect the surface for any rough spots or imperfections and sand them down thoroughly.

This will ensure the surface is smooth and even, providing a solid foundation for the final touches.

Once the surface is smooth, it’s time to apply a concrete sealer to protect it from potential damage and wear and tear. The sealer is a barrier between the concrete and external factors such as water and other substances.

This barrier helps to prevent the penetration of water and other substances into the concrete, which can lead to cracks and other forms of damage over time.

By taking these critical steps, you can ensure that your concrete project is aesthetically pleasing but also durable and resilient. With a smooth surface and proper protection, your concrete project will look great and last years.


Maintaining your patio is essential to keeping it looking its best and ensuring it stays in good condition for years to come. To begin with, cleaning your patio regularly is crucial.

This involves sweeping away any debris or dirt that may accumulate on the surface and washing it with a mild detergent and water to remove any stains or marks. 

Apart from cleaning, monitoring your patio for any cracks or damage that may occur over time is essential. This can happen due to weather conditions, heavy traffic, or general wear and tear.

If you notice any cracks or damage, it is crucial to repair them as soon as possible to prevent further damage from occurring. You can do this by filling in any cracks or replacing damaged pavers, depending on the severity of the damage.

It is also important to note that different types of patios may require different types of maintenance. For instance, a wooden deck may need to be sealed or stained periodically, while a concrete patio may require periodic power washing to remove any stubborn stains.

By following these maintenance tips, you can ensure that your patio remains safe and enjoyable for you and your family to spend time together. Additionally, a well-maintained patio can add value to your home and enhance the overall aesthetic appeal of your outdoor space.


In the end, if you wish to renovate your concrete patio, there are a few essential steps to follow. Although it may appear daunting, it is a manageable and rewarding project as long as you have the right tools, materials, and preparation.

First and foremost, inspect the surface for any damage or cracks that may require repair.

Additionally, assess the slope to ensure proper drainage and prevent water accumulation.

Once the surface is ready, use the appropriate compound for your specific needs and allow it to dry completely before moving on to the next step.

Lastly, remember to pay attention to the finishing touches, such as smoothing out any bumps or uneven surfaces, to ensure a visually appealing and smooth surface. These tips will assist you in transforming your patio into a functional and beautiful outdoor space you can enjoy for years.
