Summer is finally here, and that means one thing: BBQ season. But before you fire up the grill and invite your friends over, take a quick look at your garden patio and consider if now is the perfect time to clean and seal patio surfaces. In fact, ensuring your patio is cleaned and sealed helps it look its best for the season.

Over the winter and spring, paving can easily become covered in dirt, algae, moss, and stubborn weeds. A dull, dirty patio can dampen the vibe of your summer gatherings. The good news? With a little bit of elbow grease—and a good quality sealer—you can bring your paving back to life and protect it from inevitable dropped sausages and spilt drinks. Afterwards, you’ll see why a clean patio is worth the effort to seal and protect for the long term.

Here is a simple, step-by-step guide to cleaning and sealing your garden patio just in time for summer. Every step will help you with the process of cleaning and sealing patio spaces effectively.

Step 1: Clear the Deck and Sweep

Before you introduce any water or chemicals, you need a completely clear canvas. This will make it easier when you begin to clean and seal your patio area thoroughly.

  • Move everything: Take all furniture, plant pots, and the BBQ off the patio.

  • Pull the weeds: Remove any weeds growing between the joints. Make sure to pull them out by the root so they do not grow straight back.

  • Give it a hard sweep: Use a stiff-bristled brush to remove loose dirt, leaves, and debris. When the surface is free of debris, you’re ready to clean and then seal the patio for lasting results.

Step 2: Wash the Paving

Now it is time to remove the built-up grime and algae. Properly washing makes it easier to clean and seal patio stones and enhances their appearance.

  • Warm soapy water: For a lightly soiled patio, a bucket of warm water mixed with mild dish soap and a stiff brush works wonders.

  • Patio cleaner: For tougher stains or black spots, purchase a specialized patio cleaner. Always follow the manufacturer’s instructions for the best cleaning and sealing patio outcomes.

  • Pressure washing: A pressure washer is highly effective, but you must be careful. Hold the nozzle at a 45-degree angle and do not hold it too close to the paving, as extreme pressure can damage the surface of the stone and blast out the jointing sand. Once done, you’re paving the way for sealing your clean patio for summer.

Step 3: Top Up the Jointing Sand (For Block Paving)

If you have a block paving driveway or patio, cleaning will likely wash away some of the sand between the blocks. Wait for the patio to dry completely, then sweep fresh kiln-dried sand over the surface, making sure it fills all the joints. This keeps the blocks secure and prevents new weeds from taking root. After this, the clean and seal patio process is almost finished.

Step 4: Seal for Ultimate Protection

Applying a sealer is the secret to a long-lasting, low-maintenance patio. Once you clean and seal patio stones, your maintenance tasks become so much easier.

Why seal before a BBQ? Unsealed stone and concrete are porous. If a guest drops a greasy burger or spills a glass of red wine, it will soak straight into the stone and leave a permanent stain. A good sealer creates an invisible barrier that stops stains in their tracks!

  • Ensure the patio is 100% dry before starting. Dry, clean patio surfaces are essential before sealing for the best finish.

  • Apply the sealer using a roller or a sprayer, working in small sections. Carefully sealing a patio that is fully cleaned will maximize protection.

  • Leave it to dry completely (usually 24 hours) before moving your furniture and BBQ back into place. That’s all it takes to clean and seal your patio efficiently.
