Professional Installation Guidelines

To ensure lifelong structural stability, Mountain White slabs must be laid on a full continuous wet mortar bed (approx. 30mm to 40mm thick) over a thoroughly prepared and compacted MOT Type 1 aggregate sub-base. Avoid spot-bedding under any circumstances; hollow voids beneath the slabs create localized stress points vulnerable to cracking under heavy pedestrian loads. Because vitrified stoneware cannot absorb moisture from the bedding layer, a dedicated porcelain bonding slurry primer must be painted over the reverse side of every slab right before laying to create a permanent bond.

Maintain precise joint gaps of 3mm to 5mm and fill using a high-quality outdoor jointing grout. For a detailed breakdown of the required masonry parameters, see our official Porcelain Paving Installation Guide and verify your site specifications match the UK Paving Standards and Guidelines.
