Adding Texture To Patio Concrete: A Step-By-Step Guide

how to put a texture top on a patio concrete

Adding a texture top to a patio concrete can be a great way to enhance the look and feel of your outdoor space. There are several ways to achieve this, ranging from simple do-it-yourself (DIY) methods to more complex processes that may require professional assistance. One common approach is to use a concrete overlay product, such as the one offered by SUNDEK, which allows for a wide range of colours, patterns, and textures to be applied to the existing concrete surface. This method is often faster and more cost-effective than complete replacement. Additionally, you can consider using outdoor epoxy paint with a non-slip additive, or clear outdoor paint mixed with clear/grey grit to create a textured finish. Before beginning any texturing project, it is important to ensure that the concrete surface is thoroughly cleaned and prepared, as this will impact the final result.

Using a concrete overlay

If your patio concrete is worn out and damaged, you can consider a concrete overlay to resurface it. Concrete overlays can be applied from feather edge thin up to 2" thick in some cases. They can be finished smooth, broom finished, or even coloured and stamped to create texture.

To apply a concrete overlay, you will need to prepare the existing concrete surface by cleaning and repairing it. This includes pressure washing the concrete, fixing any cracks, and applying a primer. Once the surface is prepared, you can mix and apply the concrete overlay according to the manufacturer's specifications.

There are various types of concrete overlay mixes available, such as:

  • Trowel mix: Used for overlay applications like broom finish and skip trowel finish.
  • Flat Top: Can be used as a self-levelling underlayment mix, concrete repair, and resurfacing.
  • Pro Micro-Top: A micro-thin concrete resurfacer that can be coloured and stained.
  • Stamp Mix: Used for stamped concrete finished surfaces.
  • Spray Mix: Used for smooth finishes, knockdown finish, stencilling, and texture coats.

After applying the overlay, you will need to seal it with a concrete sealer to protect it. With the right decorative concrete products, you can create an unlimited array of colours, patterns, and textures to make your patio stand out.

Adding colour with concrete stain or dye

Adding colour to your concrete patio is a great way to enhance the look and feel of your outdoor space. There are a variety of concrete stains and dyes that can be used to achieve different effects.

Concrete Stain

Concrete stain is a popular choice for colouring concrete patios as it soaks into the concrete, resulting in a permanent and durable finish. There are two main types of concrete stain: acid-based and water-based.

Acid-Based Stain

Acid-based stain chemically reacts with the concrete to create a natural-looking, permanent finish. It is long-lasting, resistant to fading, and will not peel or chip. This type of stain produces a mottled look similar to natural stone.

Water-Based Stain

Water-based stain is available in a wider range of colours and is generally easier to apply. It bonds to the concrete surface, filling the pores to create a coloured film. Water-based stain is less toxic, dries more quickly, and can be layered with multiple colours to create a unique look.

Concrete Dye

Concrete dye is another option for colouring concrete. Dye particles penetrate the concrete surface and spread out to create a uniform colour. Dye is available in both water-based and solvent-based formulas and can be applied with a sprayer, roller, or brush.

Tips for Applying Concrete Stain or Dye

  • Choose a concrete stain or dye that fits your needs and test it on a small section of concrete to ensure you are happy with the colour and coverage.
  • Prepare the concrete surface by removing any previous coatings, cleaning it thoroughly, and repairing any cracks.
  • Protect surrounding areas from overspray by covering them with plastic drop cloths or paper.
  • Apply the stain or dye in even, overlapping sprays or coats, working in sections as needed.
  • Allow the concrete to dry thoroughly before applying a sealer to protect the finish and enhance the colour.

By following these steps and choosing the right products, you can successfully add colour to your concrete patio and create a unique and inviting outdoor space.

Using a stamped concrete product

Stamped concrete is a great way to add texture to your patio. This process involves imprinting, patterning, or embossing concrete to resemble brick, slate, flagstone, stone, tile, or wood. The technique of stamping concrete dates back to ancient Roman times, but it became popular for decorative use in the late 20th century.

Stamped concrete overlays are a durable and economical option for upgrading, repairing, or enhancing existing concrete. They can be applied over old concrete to create permanent patterns and textures, saving you the cost and hassle of tearing out and replacing concrete.

Here's a step-by-step guide to using a stamped concrete product for your patio:

  • Evaluate the current concrete surface: Inspect the existing concrete for any structural damage, such as large cracks, settling, or significant surface deterioration. Ensure that the underlying concrete is structurally sound before proceeding.
  • Surface preparation: Remove any loose or weakened material from the surface. Clean the surface and ensure it is free of contaminants to facilitate a strong bond with the overlay. Refer to technical guidelines for surface preparation.
  • Choose a stampable overlay product: Select a product specifically designed for stampable overlays, such as the Brickform Stampable Overlays (OL-60 or SC-60). These overlays are thicker than micro-toppings and are made from a blend of polymers, fine aggregates, and cement, making them durable and easily workable.
  • Mix and install the overlay: Follow the manufacturer's instructions for mixing and installing the chosen product. Apply the overlay using the appropriate tools, such as a gauge rake, squeegee, and/or trowel.
  • Texture the overlay: Once the overlay has set sufficiently, it's time to add texture. Use traditional stamps, texture skins, or rollers to create the desired pattern or texture. Be mindful of the impression depth to avoid bottoming out with the stamp.
  • Add color (optional): Stamped concrete can be coloured using integral colours, colour hardeners, stains, or antique release agents. You can choose to add colour to the overlay before texturing or apply stains after the texturing process to add depth and uniqueness to your design.
  • Seal the concrete (optional): While sealing is not mandatory, it can provide added protection and enhance the appearance of your stamped concrete patio.

By following these steps and choosing the right stamped concrete product, you can transform your plain concrete patio into a beautiful and durable surface that resembles natural stone, brick, or wood.

Removing old paint with a pressure washer

To put a texture top on a patio concrete, you may first need to remove old paint. Here is a guide on how to do this using a pressure washer:

Pressure washing is an efficient way to remove paint from concrete due to its speed and force. Here are the steps to pressure wash your concrete surface and remove paint:

  • Prepare the pressure washer: Set up the pressure washer with a 15-degree nozzle and adjust the pressure to 2,500–3,000 PSI.
  • Start at the highest point: Begin pressure washing at the highest point of the concrete and work your way down.
  • Maintain a safe distance: Keep the nozzle about 12 inches from the surface and move it in a back-and-forth motion over the paint.
  • Adjust as needed: For stubborn areas, increase the pressure or decrease the distance, but be cautious not to damage the concrete.
  • Seal the concrete: Once the paint is removed and the concrete is completely dry, seal the concrete.

Pros and Cons of Using a Pressure Washer

Pros:

  • Power washing is a safer and more environmentally friendly alternative to chemical strippers.
  • It can remove paint, grime, and dirt.

Cons:

  • Pressure washing may not be as effective at removing paint as other methods.
  • It has low production rates, meaning it is the least efficient method for removing paint.
  • If not used carefully, it can cause damage to the concrete, including cracking, breaking, or chipping.

Ensuring a clear edge by cutting back overgrown grass

To ensure a clear edge when cutting back overgrown grass, it is important to use the proper tools and follow a systematic process. Here is a step-by-step guide to help you achieve a neat and tidy edge:

  • Assess the Overgrowth: Before beginning, evaluate the extent of the overgrowth. If there is significant overgrowth on the hard surface, consider using a stick edger or a hula-hoe (also known as a scuffle hoe or "action" hoe) to cut through the grass efficiently.
  • Prepare the Area: Ensure the grass is dry to make the cutting process easier. If there is dirt buildup along with the grass overgrowth, use a square-point shovel to loosen and remove the dirt, working from the middle of the walkway towards the edge.
  • Use a Stick Edger: Run the stick edger along the edge of the concrete to separate the grass from the hard surface. Make multiple passes if needed, especially if the grass is densely overgrown.
  • Trim with a String Trimmer: Use a string trimmer to cut away any remaining grass that is sticking to the concrete. This step will help ensure a clean edge.
  • Blow or Rake Debris: Once the majority of the grass has been cut away, use a blower or rake to remove any remaining grass clippings and debris from the concrete.
  • Wash the Area (Optional): For a more professional look, consider washing down the area with a hose or pressure washer to remove any remaining dirt or residue.

By following these steps, you can effectively cut back overgrown grass along a concrete edge, creating a neat and well-defined border. Maintaining a clear edge not only enhances the appearance of your outdoor space but also helps prevent grass from encroaching onto the concrete surface.
