Step-by-Step Guide to Laying a Patio

Porcelain paving is durable, low-maintenance, and stylish, but laying it correctly is essential for a long-lasting and professional finish. Follow this step-by-step guide to ensure a secure, level, and visually stunning installation.

Step 1: Gather Your Tools & Materials

✔ Porcelain Paving Slabs – Ensure you have the correct sizes and quantities.
✔ Sub-Base Material – MOT Type 1 or compacted hardcore for stability.
✔ Priming Slurry – Essential for strong adhesion between the porcelain and mortar bed.
✔ Full Mortar Bed – A mix of sharp sand and cement (4:1 ratio).
✔ Tile Spacers – To maintain consistent joint widths (3-5mm recommended).
✔ Notched Trowel & Rubber Mallet – For precise levelling.
✔ Spirit Level & String Line – To maintain even paving levels.
✔ Jointing Compound – A high-quality exterior grout for porcelain paving.

Step 2: Prepare the Base

1️⃣ Excavate the Area – Dig down at least 150-200mm below the final surface level to allow space for the sub-base, mortar, and paving.
2️⃣ Lay the Sub-Base – Fill the area with 100-150mm of MOT Type 1 hardcore, compacting it in 50mm layers using a vibrating plate compactor.
3️⃣ Ensure a Solid Foundation – The sub-base should be firm, level, and well-compacted to prevent sinking or shifting over time.

Step 3: Apply a Priming Slurry to the Paving Slabs

Porcelain paving is non-porous, meaning it won’t naturally bond to the mortar like sandstone or limestone. Applying a priming slurry creates a strong bond between the porcelain and the mortar bed.

✔ Mix the Priming Slurry – Follow the manufacturer’s instructions for a thick, paint-like consistency.
✔ Apply to the Back of Each Slab – Use a brush or roller to coat the entire underside before laying.

Tip: Don’t let the priming slurry dry before placing the slab onto the mortar!

Step 4: Lay the Paving on a Full Mortar Bed

1️⃣ Mix the Mortar Bed – Combine sharp sand and cement at a 4:1 ratio, adding water until it forms a firm but workable consistency.
2️⃣ Lay a Full Bed – Spread the mortar at least 30mm thick over the prepared base.
3️⃣ Position the Paving Slabs – Carefully place each slab onto the mortar bed, gently tapping with a rubber mallet to level.
4️⃣ Maintain Consistent Joints – Use 3-5mm tile spacers between slabs for a uniform, professional finish.
5️⃣ Check Levels – Use a spirit level and string line to ensure even surfaces with a gentle fall (1:60 gradient) for drainage.

Step 5: Allow the Mortar to Set

✔ Leave the paving undisturbed for at least 24-48 hours, avoiding foot traffic to allow the mortar to fully cure.
✔ Check for any slight movements or misalignment and adjust before the mortar sets completely.

Step 6: Jointing & Sealing (If Required)

Once the paving is firmly set, it’s time to fill the joints and ensure a clean, weatherproof finish.

1️⃣ Choose the Right Jointing Compound – Use a porcelain-compatible grout or brush-in jointing compound.
2️⃣ Apply the Grout – Work in small sections, using a grout float or brush to press the grout into the joints.
3️⃣ Clean Off Excess Grout – Wipe off residue immediately with a damp sponge or cloth before it dries.
4️⃣ Final Rinse – Once fully cured, rinse the paving with clean water.

Optional: Porcelain paving is low-maintenance and doesn’t require sealing, but for added protection, you may apply a porcelain sealer to prevent long-term staining.

Final Tips for a Perfect Porcelain Paving Installation

✔ Plan Your Layout First – Dry-lay the slabs before installation to ensure the best visual arrangement.
✔ Ensure Proper Drainage – A slight gradient will prevent water pooling.
✔ Work Efficiently – Once mortar is spread, lay the slab immediately to ensure strong adhesion.
✔ Keep the Surface Clean – Regularly wipe off grout residue and mortar splashes during installation to avoid stains.

By following this step-by-step guide, you’ll achieve a flawless porcelain paving installation that’s not only stunning but also durable, long-lasting, and easy to maintain.

How to Clean & Maintain Indian Sandstone 

Routine Cleaning – Keeping Your Porcelain Paving Looking Fresh

Step 1: Sweep Away Dirt & Debris

✔ Use a soft-bristle broom or brush to remove dirt, leaves, and loose debris regularly.
✔ If the area is dry, a leaf blower can help clear dust and small particles quickly.

Step 2: Wash with Warm Soapy Water

✔ Mix warm water with a pH-neutral cleaner or mild washing-up liquid.
✔ Use a soft mop or sponge to clean the surface—avoid abrasive materials that could scratch the finish.
✔ Rinse thoroughly with clean water to prevent residue build up.

Step 3: For Deeper Cleans, Use a Pressure Washer (Carefully!)

✔ Use a medium pressure setting and keep the nozzle at least 30cm away from the surface.
✔ Avoid using high pressure on jointing compounds, as it may weaken the grout between slabs.

Tip: Unlike natural stone, porcelain paving is non-porous, meaning it won’t absorb water or stains, making deep cleaning much easier!

Removing Stubborn Stains from Porcelain Paving

Porcelain paving is highly stain-resistant, but some stubborn marks may still require extra care.

🛑 Avoid acidic or bleach-based cleaners, as they can damage the surface.

Tip: Always test any new cleaner on a small area first to check compatibility with your paving.

Seasonal & Long-Term Porcelain Paving Care

Spring & Summer – Keeping It Looking Perfect

✔ Regularly sweep and wash to keep dust and pollen from settling.
✔ Check for weeds between joints (although porcelain paving with proper jointing has minimal weed growth!).

Autumn – Preparing for Colder Weather

✔ Remove fallen leaves to prevent organic stains.
✔ Give the surface a final wash before winter to remove dirt that could become slippery in damp conditions.

Winter – Preventing Ice & Slips

✔ Avoid using rock salt, as it can leave residue—opt for grit or sand instead.
✔ If needed, use warm water and a mild cleaner to remove frost build up.

Do I Need to Seal Porcelain Paving?

No! One of the biggest advantages of porcelain paving is that it doesn’t require sealing. Unlike natural stone, which is porous and needs protection, porcelain tiles are non-absorbent, meaning:
✔ No risk of staining from spills.
✔ No water absorption leading to frost damage.
✔ Minimal maintenance compared to sandstone, limestone, or concrete paving.

However, if you’re using grout between the slabs, some people choose to seal the grout to reduce the risk of dirt build up over time.

Final Tips for Long-Lasting Porcelain Paving

✔ Clean regularly to keep the surface free from dirt and debris.
✔ Avoid harsh chemicals like bleach or acidic cleaners.
✔ Use the right tools – soft brushes, mops, and non-abrasive cleaners are best.
✔ Rinse thoroughly after cleaning to prevent streaks and residue.

By following these simple maintenance steps, your porcelain paving will stay looking as fresh and stunning as the day it was laid.
