Cutting and Finishing Large-Format Tile: Tools and Technologies

Cutting large-format tile is the art of precision

Large-format tile impresses with its beauty and monolithic look, but working with it needs a special approach, especially when it comes to cutting. A slab of 120×240 cm or 160×320 cm is not a material you can cut with an ordinary tile cutter on your knee.

M-STONE is equipped with a full set of professional equipment for cutting and finishing large-format tile and natural stone. Our craftsmen make cuts of any complexity, from straight lines to complex curved cut-outs.

Features of cutting large-format tile

Why a large format is a special challenge

Size and weight

• A 120×240 cm slab weighs 50-70 kg
• At least two people are needed to handle it
• It is awkward to work without special equipment
• A high risk of damage with careless handling

Fragility

• Thin porcelain stoneware (6-10 mm) cracks easily
• Stress from a wrong cut spreads across the whole slab
• Internal defects may show up during cutting
• Tool vibration can cause a chip

Precision

• On a large slab any deviation is multiplied
• An error of 1 mm per metre = 2.4 mm on a 240 cm slab
• Crooked cuts cannot be hidden
• Joints with other slabs will reveal every inaccuracy

The cost of a mistake

• A damaged slab cannot be repaired
• There may be no spare (especially for exclusive collections)

Types of cuts

A straight cut The simplest type: cutting along a straight line parallel or perpendicular to the edge of the tile.

Use:

• Trimming the edge slabs at walls
• Forming the required size
• Splitting a slab in half

A diagonal cut Cutting at an angle to the edges of the tile.

Use:

• Diagonal laying
• Fitting to angled walls
• Decorative elements

An L-shaped cut-out A cut-out in the shape of the letter “L” to go around obstacles.

Use:

• Going around door frames
• Going around boxings and niches
• Fitting to wall projections

A U-shaped cut-out A cut-out in the shape of the letter “U”.

Use:

• Going around columns
• Going around large-diameter pipes
• Niches

A round cut-out (hole) A round hole of various diameters.

Use:

• Holes for pipes
• Holes for sockets
• Cut-outs for mixers
• Holes for spotlights

A curved cut-out Cutting along a complex curved line.

Use:

• Going around rounded elements (columns, baths)
• Decorative shapes
• Fitting to arches

A shaped cut-out Complex shapes: triangles, trapezoids, non-standard figures.

Use:

• Mosaic compositions
• Decorative panels
• Non-standard architectural solutions

Tools for cutting large-format tile

Technology of cutting large-format tile

Preparing to cut

1. Planning

• Determining all the necessary cuts
• Calculating the cutting layout of the slabs
• Minimising waste
• Planning the sequence

2. Marking

• Accurate measurements
• Marking with a pencil or marker
• Checking the dimensions before cutting
• Allowing for the joint width

3. Preparing the workplace

• A flat, stable surface
• Enough room to manoeuvre
• Good lighting
• Access to water and electricity

4. Preparing the tool

• Checking the condition of the blade / wheel
• Checking the water level (for wet saws)
• Setting up the stops and guides

Technique for a straight cut with a manual tile cutter

Step 1: positioning

• Place the tile face up
• Align it with the cutting line
• Fix it with the stop

Step 2: scoring

• Set the wheel at the start of the line
• Press evenly
• Run the wheel along the whole line in one motion
• Do not repeat the scoring!

Step 3: snapping

• Set the breaker in the centre of the line
• Press evenly on both sides
• The tile breaks along the score line

Important for large formats

• Support the slab on both sides
• Even pressure when scoring
• Do the snap with two people

Technique for a cut with an electric tile cutter

Step 1: preparation

• Fill the tray with water
• Check the condition of the blade
• Set the stop to the required size

Step 2: positioning

• Place the tile on the table
• Align the cutting line with the blade
• Press against the stop

Step 3: cutting

• Switch on the machine
• Wait for full speed
• Feed the tile slowly to the blade
• Do not push: let the blade cut
• A steady feed speed
• Cut through to the end

For large formats

• One worker feeds the tile
• The other receives it on the other side
• Support the slab so it does not sag
• Large slabs only on large machines

Technique for a 45° cut (mitre)

For forming corner joints without a visible edge.

Equipment

• An electric tile cutter with a tilting blade
• Or a special mitre machine

Technique

• Tilt the blade to 45°
• Do not cut up to the glaze: leave 0.5-1 mm
• The glaze must stay intact on the edge
• Finish the edge with sandpaper

Application

• External wall corners
• Windowsills
• Countertops
• Stairs (nosing)

Technique for curved cuts

Tool: an angle grinder with a diamond blade

Technique

• Mark the curved line on the tile
• Make a series of cuts up to the line (stopping 1-2 mm short)
• Break out the segments
• Grind the edge down to the line

Alternative: cut out with straight cuts, then finish the edge by grinding.

Technique for round cut-outs

Small holes (up to 12 mm)

• A ceramic drill bit
• A diamond drill bit
• Low speed, with water

Medium holes (12-120 mm)

• A diamond core bit of the right diameter
• Drilling with water
• Low speed
• Do not press hard

Large holes (over 120 mm)

• Marking the outline
• Drilling holes along the outline
• Joining the holes with an angle grinder
• Grinding the edge

For sinks and hobs

• Accurate marking from a template
• Drilling the corners
• Cutting the sides with an electric cutter
• Grinding for a clean edge

Finishing edges and surfaces

Types of edge finish

A factory edge An edge finished at the factory. For rectified tile it is perfectly straight.

A cut edge (unfinished) The edge after cutting. It may have micro-chips and needs finishing for visible areas.

A ground edge Finished with grinding tools. Smooth, but matt.

A polished edge Ground and polished to a shine. For visible edges of countertops and windowsills.

A bevel An edge cut at 45° or another angle. It removes the sharp edge and prevents chips.

Tools for finishing edges

Grinding discs and attachments

• Diamond pads of various grits
• From coarse (50) to fine (3000)
• Sequential working from coarse to fine

Polishing attachments

• Felt wheels
• Polishing pastes
• For the final finish

Routers for bevels

• Hand routers with diamond bits

Technique for grinding an edge

Step 1: coarse grinding (grit 50-100)

• Levelling the edge
• Removing the cutting marks

Step 2: medium grinding (200-400)

• Smoothing the surface
• Removing the scratches from coarse grinding

Step 3: fine grinding (800-1500)

• Preparing for polishing
• A smooth surface

Step 4: polishing (3000 + paste)

• Achieving the shine
