How To Repoint A Patio? Find Out Here!

Are you tired of looking at your worn-out patio? Do you want to give it a fresh new look without spending a lot of money? Repointing your patio might just be the solution you're looking for!

Repointing is the process of removing old and damaged mortar from between the bricks or paving stones on your patio, and replacing it with new mortar. It's an easy DIY project that can be completed in just a few hours, depending on the size of your patio.

In this article, we'll guide you through the steps needed to repoint your patio. We'll cover everything from assessing the condition of your patio to applying new mortar and finishing touches. Whether you're a seasoned DIY-er or have never picked up a trowel before, we've got you covered.

So grab some gloves and let's get started!

Essential Highlights

  • Assess the condition of the patio and mortar joints before beginning the repointing process.
  • Use the appropriate tools and materials, including a pointing trowel, mortar mixing tool, safety goggles and gloves, and an appropriate mortar mix.
  • Carefully remove old mortar using a cold chisel or brick set, then fill gaps with new mortar and press down firmly on each piece.
  • Allow at least 24 hours for the new mortar to set before walking on the patio, then seal the joints with a waterproof sealant and regularly clean the surface to extend the lifespan of the repointed patio.

Assessing the Condition of Your Patio

Before you start repointing, take a good look at your patio to see if there are any cracks or loose stones that could cause problems down the line. You don't want to spend time and effort repointing only to have the same issues arise again in a few months.

Check for areas where water may be pooling or where there is unevenness in the surface. These can be signs of underlying problems that need to be addressed before starting work.

Also, assess the condition of your current mortar joints. If they're cracked, crumbling, or missing entirely, then it's definitely time for some repointing. However, if they're still intact but just showing some wear and tear, then you may be able to get away with just touching up certain areas rather than redoing all of the joints.

Once you've done a thorough assessment of your patio's condition, it's time to gather the necessary tools and materials for the job ahead.

Gathering the Necessary Tools and Materials

First, you'll need to grab all the essential tools and materials to get started on this project. You'll want to have a pointing trowel, a mortar mixing tool or drill with paddle attachment, a bucket for water, a stiff brush, safety goggles and gloves, as well as the appropriate type of mortar mix for your patio.

It's important to wear gloves and goggles when handling the mortar mix as it can cause skin irritation and eye damage.

Once you've gathered all the necessary items, you can move on to removing the old mortar. This step is critical in ensuring that your repointed patio will be sturdy and long-lasting.

Removing the Old Mortar

Now that you've got all your tools and materials ready, it's time to roll up your sleeves and get to work on chiseling away at the old mortar. This is a critical step in repointing your patio because if you don't remove the old mortar properly, the new mortar won't adhere well, and your efforts will be wasted.

To effectively remove the old mortar, follow these steps:

  • Assess the area to see if building a conservatory on a patio is feasible
  • Consult with a professional builder for advice and guidance
  • Materials options for building a conservatory include uPVC and aluminium
  • Regular maintenance, such as cleaning glass panels and checking for leaks, is necessary for longevity.

With patience and persistence, you'll eventually have all of the old crumbling material removed from between your patio stones or bricks.

Now it's time for the fun part - applying new mortar!

Applying New Mortar

Ready to get your hands dirty? It's time to start applying the fresh new mortar to your patio stones or bricks!

First, mix up a batch of mortar according to the instructions on the bag. You want it to be a thick consistency that can hold its shape without sagging.

Use a trowel or similar tool to scoop up some mortar and apply it in between each stone or brick, filling the gaps completely. Be sure to press down firmly on each piece as you go along, so that the mortar spreads evenly and sets properly.

Continue this process until all of the joints are filled with fresh mortar. Once you've finished, give it at least 24 hours for the new mortar to set before walking on your patio again.

Now that you're done applying the new mortar, let's move onto finishing and maintaining your repointed patio by sealing it with a waterproof sealant for added protection against weathering and wear!

Finishing and Maintaining Your Repointed Patio

Once you've completed the mortar application, it's important to protect your hard work by sealing the joints with a waterproof sealant. This will prevent water from seeping into the pores of the mortar and causing it to crack or break down over time. Apply the sealant using a brush or roller in thin layers, being careful not to leave any gaps.

To maintain your repointed patio, it's important to regularly clean it and remove any debris that may accumulate on the surface. You can also apply a protective coating every few years to ensure that the joints remain sealed and water-resistant. Additionally, make sure to avoid using harsh chemicals or abrasive tools when cleaning, as these can damage both the sealant and the mortar itself. With proper maintenance, your newly repointed patio will provide many years of enjoyment for you and your guests.

Frequently Asked Questions

Can I repoint a patio without removing the old mortar?

Yes, you can repoint a patio without removing the old mortar. However, it's important to note that this method is not as effective and long-lasting as removing the old mortar and starting fresh. Consider your options carefully before proceeding.

How long does the new mortar take to dry before I can use the patio?

You can use your patio again within 24-48 hours after repointing the mortar. However, it's best to wait for at least a week before placing heavy objects on it. This allows the mortar to fully cure and set, ensuring a strong bond.

What is the best time of year to repoint a patio?

The best time to repoint a patio is during mild weather conditions, typically in the spring or fall. Avoid extreme heat or cold, as it can affect the curing process of the mortar and impact its durability.

Should I seal my repointed patio to protect it from the elements?

Yes, you should seal your repointed patio to protect it from weather damage. It will help prevent water absorption and keep it looking great for longer. Use a high-quality patio sealer and follow the manufacturer's instructions for best results.

Can I use regular cement instead of mortar for repointing my patio?

No, regular cement is not suitable for repointing a patio. Mortar has better bonding properties and is specifically designed for this task. Using cement may result in cracking or crumbling over time, so stick with mortar for best results.


Congratulations, you've successfully repointed your patio! By following these steps, you've restored the structural integrity and aesthetic appeal of your outdoor living space.

To ensure that your new mortar sets properly, it's important to allow it to dry thoroughly before walking on or using your patio.

After a few days, you can apply a sealant to protect against water damage and further deterioration.

With proper maintenance and occasional touch-ups as needed, your repointed patio can last for years to come.

Enjoy your revitalized outdoor oasis!
