How To Point A Patio (Easy Professional Finish)

A patio is an essential element of any outdoor living space, providing a versatile and practical area for relaxation and entertainment. However, over time, the joints between the patio pavers can deteriorate due to weather exposure and general wear and tear. Re-pointing an existing patio (or pointing a new patio) involves filling these gaps to ensure stability and aesthetics. In this step-by-step guide, we'll walk you through the process of pointing a patio, helping you achieve a durable and professional finish without the need for professional help.

Preparing your Patio for Pointing

Preparing your patio before pointing is a crucial step to ensure a successful and durable finish. The first essential aspect of preparation involves ensuring that the joint depth is clear and free from debris. Using a jointing iron or a suitable tool, carefully remove any accumulated dirt, bedding mortar, and loose material from the gaps between the pavers. Additionally, if you are repointing an existing patio, it is imperative to thoroughly scrape out the old pointing to create clean and uniform joints. This will allow the new pointing material to bond effectively, preventing premature deterioration. Once the joints are cleaned, it is essential to inspect the patio surface for any cracks, damages, or unevenness, addressing these issues before proceeding with the pointing process. Adequate preparation will pave the way for a successful and long-lasting patio pointing application.

Choosing the Best Type of Pointing for Your Patio

When it comes to pointing your patio, there are various options available, each with its unique benefits and drawbacks. Making the right decision about the type of pointing material is crucial to achieve the desired finish and longevity. Here, we'll explore some popular options, including traditional sand and cement, brush-in compound, slurry mortar, and epoxy grout, to help you make an informed choice.

  1. Sand and Cement Pointing:

Sand and cement pointing is a tried and tested method that has been used for decades. It involves mixing sand, cement, and water to create a durable and robust mortar. This type of pointing is ideal for most patios and is suitable for gaps between pavers that are at least 5mm wide. It provides a natural appearance and is relatively easy to apply.

Pros:

  • Cost-effective and readily available materials.
  • Time-tested, proven to be durable and long-lasting.
  • Can be customised by choosing different pigment dye colours.

Cons:

  • More labour-intensive compared to other options and can be back-breaking work.
  • May crack over time due to natural movements in the patio.
  • Requires dry weather.

Installation Method:

  • Mix sharp sand, cement, and water in a bucket to create a workable mortar (4-6 parts sand, 1 part cement). Ensure the mixture has the consistency of toothpaste.
  • Using a pointing trowel, apply the mortar onto the patio, pushing it into the joints between the pavers firmly and evenly.
  • Once a section is filled, use the edge of the trowel or a striking iron to remove excess mortar and create a neat finish.
  • Brush away any loose mortar from the surface using a soft brush.
  • Allow the mortar to cure for at least 24 hours before allowing foot traffic on the patio.

  1. Brush-In Compound:

Brush-in compound, also known as jointing compound or patio grout, is a mixture of sand and resin. It comes in ready-to-use bags and is specifically designed to be swept into the joints between pavers.

Pros:

  • Quick and easy to apply; no need for mixing.
  • No significant bending to install.
  • Resistant to weed growth and water penetration.
  • Can be used in wet and dry weather conditions.
  • Ideal for concrete and natural stone paving.
  • Most jointing compounds allow for any spare compound to be stored for a period of time under water. 

Cons:

  • Generally more expensive than sand and cement.
  • Can set onto the surface of the paving if not applied and rinsed away with plenty of water.
  • Often too grainy in appearance to suit porcelain paving (see our guide to porcelain grouting)

Installation Method:

  • Completely wet the patio with a hose and ensure it remains wet throughout the process.
  • Pour the brush-in compound directly onto the patio and use a stiff broom to sweep the material into the joints between the pavers.
  • Ensure the joints are adequately filled with the compound, compacting it as you go.
  • Once all the joints are filled, sweep away any excess compound from the surface and rinse with a hose.
  • When all surplus compound is removed from the surface of the stone, allow it to dry and set hard.
  • Be sure to follow the manufacturer's instructions, and avoid foot traffic until it is fully cured.

  1. Epoxy Grout:

Epoxy grout is a two-part resin-based pointing material that offers exceptional strength and durability. It is ideal for areas with heavy foot traffic, exposure to chemicals, or frequent wash-downs. It's also the jointing option used by most professionals.

Pros:

  • Highly durable and resistant to cracking, staining, and weed growth.
  • The strongest option for paving pointing
  • Can be used with concrete, natural stone and porcelain paving (see our guide to porcelain grouting)
  • Also suitable for driveways.

Cons:

  • Expensive compared to other pointing options.
  • Requires careful mixing and application due to its fast setting nature.
  • Must be removed from the surface of the paving quickly. 

Installation Method:

  • Prepare the epoxy grout according to the manufacturer's instructions, ensuring proper mixing of the two-part resin.
  • Thoroughly wet the area to be pointed and ensure it remains wet during the installation.
  • Apply the epoxy grout into the joints using a squeegee, ensuring they are filled to the top.
  • Most epoxy grouts are self levelling/ compacting and therefore require no additional handling. 
  • Take care not to allow the epoxy grout to dry on the paver surface, as it can be challenging to remove once set.
  • Allow the epoxy grout to cure fully before allowing any foot traffic on the patio/ driveway.

Remember to follow the manufacturer's instructions and take appropriate safety measures when working with any pointing material. Adequate preparation and precise installation will ensure a polished and long-lasting result for your patio pointing project.

Making the Decision:

The best type of pointing for your patio depends on various factors, such as your budget, the width and condition of the joints, the level of foot traffic, and your desired aesthetic. If you seek a cost-effective and traditional approach, sand and cement pointing may be your best bet. On the other hand, if you value convenience and have a slightly higher budget, brush-in compound or slurry mortar could be more suitable options.

For high-traffic areas or overall strength, epoxy grout offers unmatched durability and customisation possibilities, albeit at a higher cost. Ultimately, the key is to weigh the pros and cons of each method against your specific needs to achieve the perfect balance of functionality and aesthetics for your patio.

Remember, regardless of the pointing material you choose, taking the time to properly prepare the patio surface and follow the correct application techniques will ensure a professional and long-lasting finish for your outdoor space.
