What Do You Use to Lay Porcelain Slabs Properly
What Do You Use to Lay Porcelain Slabs for a Flawless Finish?
Porcelain slabs have emerged as one of the most versatile and design-forward choices in interior and exterior luxury surfaces. Their ultra-compact, non-porous characteristics make them ideal for countertops, walls, floors, and even custom furniture. But when it comes to installing these stylish yet technical surfaces, understanding what you use to lay porcelain slabs is vital for achieving both exceptional aesthetics and long-term durability.
At Zicana Boutique’s Porcelain Slabs Collection, we cater to both discerning homeowners and elite design professionals who demand nothing less than precision in every detail. In this guide, we’ll explore the tools, techniques, and considerations involved in laying porcelain slabs the right way—from substrate prep to specialized adhesives and everything in between.
Why Choose Porcelain Slabs?
Before diving into the installation specifics, let’s briefly review why porcelain slabs are a top-tier surface material. Made from refined clays and fired at extremely high temperatures, porcelain is both aesthetically transcendent and structurally elite. Designed to mimic the look of natural stone, wood, or concrete, it’s a practical alternative for kitchens, bathrooms, floors, and walls where resilience is just as important as beauty.
- High durability and resistance to scratches, heat, and chemicals
- Low porosity makes it hypoallergenic and stain-resistant
- Eco-friendly production with recycled content options
- Ideal for seamless large-format installations
The popularity of porcelain is reflected in the popularity of luxury lines like our Raphael Porcelain Collection and Florim Collection, each offering masterful Italian craftsmanship and timeless texture.
Tools and Materials: What You Use to Lay Porcelain Slabs Effectively
Laying porcelain slabs requires precision and the right set of tools and materials to avoid mistakes such as uneven leveling, premature cracks, and weak bonding. Here’s what you need:
- Level Subsurface: SLU (Self-Leveling Underlayment) or cement backer board ensures the foundation is perfectly flat
- Flexible Thinset Mortar: Use a polymer-modified, non-sag mortar specifically rated for large-format porcelain tiles
- Large Format Tile Trowel: Typically 1/2" x 1/2" square-notch trowel for optimal adhesive coverage
- Suction Cups or Slab Lifters: For safe and accurate handling of large slab panels
- Tile Leveling System: To mitigate lippage between adjacent slabs
- Diamond Blade Wet Saw: For clean, precise cuts
- Grout and Caulking: Select a fine-grain, non-sanded grout for smaller joints, and high-silicone caulk for expansion joints
Every installation should start with cleanliness and dry fitting to ensure that the slabs are acclimated and positioned accurately before permanent placement.
Steps to Masterful Porcelain Slab Installation
Regardless of where your project lies—residential renovation, high-rise commercial build, or custom luxury furniture piece—the following steps will serve as the architectural blueprint for how to install porcelain slabs correctly:
- Prepare the Substrate: Ensure a fully cured, level surface with no movement. Moisture barriers may be required for wet zones.
- Dry Fit and Planning: Lay out your slabs without adhesive to plan cuts, joints, and patterns effectively.
- Apply Mortar: Use the large-format trowel to apply mortar evenly. Back-buttering the slab is also recommended to ensure 100% coverage.
- Set the Slabs: Use suction cups and leveling systems to place the slab firmly and evenly. Adjust to eliminate air pockets.
- Grouting and Sealing: Follow manufacturer guidance on cure times before applying grout or silicone caulk to joints. Use non-acidic cleaners afterward.

Frequently Asked Questions
Do I need a professional to lay porcelain slabs?
While it’s possible for experienced DIYers to install porcelain slabs, we always recommend hiring a certified installer, especially for large-format or vertical applications. The precision required for proper adhesion, leveling, and cutting can make professional labor a sound investment.
Can porcelain slabs be installed over existing tile?
Yes—provided the existing tile is flat, well-adhered, and clean. Use a bonding primer and check compatibility with your thinset mortar. However, many professionals prefer to remove old tile to reduce unnecessary height and ensure substrate integrity.
What adhesive works best for porcelain slabs?
A polymer-enhanced thinset mortar that meets ANSI A118.15 is ideal. This adhesive ensures maximum flexibility and bonding strength, particularly important for large-format porcelain applications.
How thick are porcelain slabs?
Porcelain slabs typically range from 6mm to 12mm in thickness. Thinner slabs (6mm) are often used for wall cladding and furniture, while thicker slabs (12mm) are better suited for countertops and flooring due to added durability.
