Whether you're working with large living room installations or intricate bathroom spaces, proper laying techniques determine both the aesthetic outcome and long-term performance of the surface.


What is the proper way to install large porcelain slabs?


The foundation of successful porcelain slab installation begins with meticulous surface preparation. Professional installers start with a sub-base or substrate that is sound and stable, followed by a mortar / glue base layer of between 10 and 20 mm thickness – depending on the thickness and size of the slab. This careful preparation ensures structural integrity and prevents future movement or cracking.


It is also crucial that the areas to be laid or fixed with large format slabs be calculated based on how many slabs will be required, rather than the traditional method of how many m2 of area is to be covered. In most cases the wastage from cutting of large slabs will be greater than that of smaller tiles, and this must be allowed for when calculating and ordering slab materials.


Large format slabs require specialized handling techniques that only skilled professionals can provide. During installation, contractors use precision tools including spirit levels, high-quality mortars / glues, and spacers to maintain consistent 3-5 mm gaps between slabs - depending on the surfaces being covered.


For marble-effect porcelain stoneware, strategic positioning ensures veining patterns catch light optimally, enhancing the natural texture that makes these surfaces so beautiful in contemporary design.


How do you lay porcelain slabs?


The grouting phase plays a vital role in creating stable, long-lasting surfaces. Expansion joints between slabs absorb natural movement and contractions, preventing structural stress. Professional application techniques ensure clean, uniform joints that complement the overall design aesthetic.

Post-installation finishing involves carefully removing adhesive residue and debris, followed by thorough cleaning to reveal pristine surfaces. The low-maintenance nature of porcelain slabs makes them ideal for both high-traffic commercial spaces and residential applications.
