Hire Professionals
Fitting large format porcelain slabs isn’t a DIY project since the slabs you’re dealing with are large in size. Make sure to hire professional and experienced installers who are familiar with the use of tools and installation to minimise the risks of loss or damage.
Prepare your Surface
The installation of slabs will be uneven if there are bumps, holes, or a need for levelling on the underfloor. Make sure to level the surface before installation to avoid gaps between slabs, especially if you’re installing them in places with the use of water.
Use Appropriate Cutting Tools
Cutting slabs to fit your floors and walls during the installation is important. It requires specialised cutting tools to get precise and accurate cuts. Arrange tools like wet saws and a continuous rim diamond blade for a perfect fit of slabs according to the floor.
Choose Right Adhesives
large format porcelain slabs are larger than average tiles and demand a special adhesive for a strong grip. Use high-quality adhesive between slabs and your surface. This will not only keep them in place over time, but also give room for slight movement to avoid cracking.

Test Your Slabs
Test the slabs with a dry layout to verify measurement and placement, matching your desired pattern. With this testing, you can get a visually appealing outcome after applying the adhesive without mistakes.
Consider Expansion and Contraction
Large format Porcelain slabs can expand and contract with temperature changes. If you don’t leave proper space for expansion or contraction, cracking can occur over time. Leave proper joints, especially in outdoor projects.
