Attic Stock Recommendation: Trade practice recommends ordering 1 extra unopened box (1.44 m²) to preserve matching production dye lots for future architectural alterations.

Craftsman Trade Advice

Essential technical rules from master tilers for durable tile installations.

Substrate Prep

Uncoupling Membrane & 100% Adhesive Wetting

Long 120×60 cm slabs require crack-isolation membranes on heated screeds. Back-butter every slab with a flat trowel coat before embedding into notched adhesive ribs to eliminate hollow points.

Sightline

Run Long Slab Dimensions Parallel to Light

Orient the 120 cm length parallel to incoming window natural light. This highlights the grand proportions of the slab and conceals minor perpendicular joint micro-variations.

Joint Physics

1/3 Offset Rule & Leveling Spacers

Never install 120 cm slabs in a 50% brick bond. Restrict staggered offsets to 33% or 25% to break crowning apexes, and use screw-cap leveling systems across all slab intersections.

Frequently Asked Questions

How many 120×60 cm tiles are in one square meter?

There are exactly 1.39 tiles of 120×60 cm in one square meter. Factoring in a 2 mm joint and 10% cutting allowance, calculate approximately 1.55 tiles per square meter.

Can 120×60 cm tiles be laid in a 50% brick bond pattern?

No, 120×60 cm tiles must not be set in a 50% brick bond. Long porcelain tiles crown naturally during firing, so a 50% offset creates excessive lippage. A 1/3 offset or straight grid is recommended.

What grout joint width should I use for 120×60 cm tiles?

A 2 mm to 3 mm grout joint width is standard for rectified 120×60 cm slabs. A 2 mm joint delivers an architectural luxury appearance while accommodating thermal substrate movement.

Are 120×60 cm tiles suitable for floors or walls?

Yes, 120×60 cm slabs are versatile for both floors and walls. On bathroom walls, vertical orientation creates dramatic ceiling height, while horizontal floor layouts elongate open spaces.
