How to Lay Porcelain Paving: A Step-By-Step Guide

Porcelain paving slabs have become a popular choice for outdoor spaces due to their durability, low maintenance, and luxurious appearance. From Italian porcelain to wood effect porcelain and large format tiles, there are many different options to choose from. However, cutting these slabs to fit your specific design can be challenging if you’re not equipped with the right tools and techniques. 

In this guide, we will help you navigate your porcelain paving, walking you through the step-by-step process of how to safely cut your tiles to ensure a precise and professional finish.

Tools and Materials You Will Need

• Diamond Blade Wet Saw or Angle Grinder: A wet saw with a diamond cutting blade is ideal for cutting porcelain slabs. An angle grinder with a diamond blade can also be used, but it may not provide as clean a cut.
• Measuring Tape: Accurate measurements are crucial for ensuring your slabs fit perfectly.
• Straight Edge or Ruler: Useful for marking straight lines on the slab.
• Pencil or Marker: For marking where you need to cut.
• Clamps: To hold the slab in place while cutting.
• Protective Gear: Safety glasses, gloves, and ear protection are essential to protect yourself from dust and noise.
• Water Source: If you’re using a wet saw, you’ll need a water source to keep the blade cool and reduce dust.

Step-by-Step Guide to Cutting Porcelain Paving Slabs

Step 1: Measure and Mark Your Chosen Area

Start by measuring the area where the porcelain slab will be placed. Use a measuring tape to get precise dimensions. Transfer these measurements onto the slab using a pencil or marker. Ensure your lines are straight and clear; using a straight edge or ruler will help.

Step 2: Set Up Your Cutting Area

Choose a large, flat surface for cutting to ensure maximum stability when cutting. If using a wet saw, ensure it’s positioned near a water source. If using an angle grinder, make sure you are in a well-ventilated area to manage the dust.

Step 3: Secure the Slab

Place the porcelain slab on the saw or workbench and secure it with clamps. This prevents the slab from moving during cutting, ensuring a clean and accurate cut.

Step 4: Cut with a Wet Saw

If you’re using a wet saw:

1. Turn on the water supply to the saw.
2. Align the marked line with the saw blade.
3. Gently push the slab into the blade, applying steady pressure. Let the saw do the work—forcing it can lead to uneven cuts or damage to the slab.
4. Follow through with the cut slowly and consistently until the slab is divided.

Step 5: Cut with an Angle Grinder

If you’re using an angle grinder:

1. Fit the grinder with a diamond blade designed for porcelain.
2. Hold the grinder with both hands and turn it on.
3. Begin cutting along the marked line, applying light and even pressure.
4. Make several passes along the line, gradually deepening the cut with each pass until the slab is completely cut through.

Step 6: Smooth the Edges

Once you’ve made your cut, the edges of the slab may be rough. Use a diamond polishing pad or a sanding stone to smooth out any rough spots. This will ensure the edges are safe to handle and provide a more professional look.

Tile Cutting Safety Tips

Safety is paramount when it comes to cutting porcelain tiles. Ensure you adhere to the recommended safety precautions by taking the following precautions:

• Always wear protective gear, including safety glasses, gloves, and ear protection.
• Work in a well-ventilated area to avoid inhaling dust.
• Keep fingers and hands away from the cutting blade at all times.
• Follow the manufacturer’s instructions for your tools to ensure safe and proper use.
