Learn how to repoint a patio with this easy, step-by-step guide. Discover professional tips to keep your patio looking flawless and why hiring experts like ADC Pressure Washing makes a difference.
Overview
Patios are one of the most cherished features of any UK garden, offering a perfect place to relax, host BBQs, or simply enjoy your outdoor space. However, over time, the joints between your paving slabs can become cracked, loose, or covered in weeds — making your beautiful patio look tired and unsafe.
That’s where repointing comes in. In this comprehensive guide, we’ll show you how to repoint a patio step-by-step, what materials you need, and why hiring a professional like ADC Pressure Washing & Exterior Cleaning can save you time and ensure long-lasting results.
What Is Patio Repointing?
Patio repointing is the process of replacing or renewing the mortar (also known as jointing compound or pointing) between paving slabs. Over time, weather, foot traffic, and general wear and tear cause the original mortar to degrade, which can lead to:
- Weeds growing in the joints
- Loose or wobbly slabs
- Water pooling and drainage issues
- A tired, neglected appearance
Knowing how to repoint a patio properly ensures structural integrity, prevents further damage, and restores your patio’s aesthetics.
Signs Your Patio Needs Repointing
Not sure if it’s time to repoint? Here are some clear signs to look for:
- Cracked or missing mortar between slabs
- Loose or uneven paving stones
- Weeds or moss growing in the joints
- Water not draining properly
- The patio seems generally worn and tired
If your patio shows any of these signs, it’s time to consider repointing before the damage worsens.
Tools and Materials You’ll Need
Before diving into how to repoint a patio, gather the following tools and materials:
Tools:
- Hammer and chisel or angle grinder (to remove old mortar)
- Pointing trowel
- Bucket
- Brush or broom
- Garden hose or water sprayer
- Protective gloves and goggles
Materials:
- Patio jointing compound (ready-mix or resin-based) OR
- Traditional mortar mix (sand and cement)
- Water (if using traditional mortar)
How to Repoint a Patio: Step-by-Step Instructions
Let’s walk through how to repoint a patio the right way. This process typically takes a few hours to a day, depending on the size of the area and weather conditions.
1: Remove the Old Mortar
Using a hammer and chisel or an angle grinder (for larger areas), carefully remove the old, crumbling mortar from between the slabs. Be careful not to chip or damage the paving stones.
- Clear to a depth of at least 15–20mm
- Sweep away all dust and debris once finished
Tip: A pressure washer can help clean out the joints before applying new mortar — and that’s something we at ADC Pressure Washing specialise in.
2: Clean the Joints Thoroughly
It’s crucial to clean out any remaining debris, moss, or weeds. A stiff brush and water or even a light pressure wash will ensure the new mortar adheres properly.
Let the area dry before proceeding if you’re using a dry jointing compound.
3: Mix Your Mortar (If Not Using Pre-Mix)
If you’re going the traditional route, mix three parts sand to 1 part cement with just enough water to create a stiff, workable consistency. Avoid making the mix too wet, as this weakens the final result.
Note: Resin-based or polymeric jointing compounds are easier to apply and require less labour. They’re especially effective for modern patios.
4: Apply the New Mortar
Using a pointing trowel, press the mortar or compound firmly into the joints.
- Work in small sections to avoid drying too quickly
- Press the material down to eliminate air gaps
- Smooth over the surface with a trowel or pointing iron
5: Finishing Touches
Once filled, smooth out the joints for a neat, uniform look. Brush away any excess material and lightly mist the area with water if required by your compound.
Let the patio cure undisturbed. This usually takes 24–48 hours, depending on the weather and the material used.
