With the rapid growth of interior renovation and space upgrading projects, sintered stone installation over existing tiles has become a highly efficient and environmentally responsible construction method. This advanced technique allows sintered stone slabs to be installed directly on old ceramic tile surfaces, without removing or demolishing the existing tiles.
By combining professional bonding technology with the superior performance of sintered stone, this system offers a faster, cleaner, and more sustainable solution for interior wall and floor renovation.
Professional Sintered Stone Installation Process (Tile-Over-Tile System)
Below is the standardized construction workflow used for sintered stone renovation applications, ensuring safety, durability, and long-term performance:
Step 1: Existing Tile Surface Inspection
The original ceramic tile surface is carefully inspected to ensure:
-
Firm adhesion to the substrate
-
No hollow or loose tiles
-
Acceptable flatness and structural stability
Any unstable areas are reinforced before proceeding.
Step 2: Interface Treatment (Bonding Primer Application)
A professional interface treatment agent is applied to the old tile surface to enhance bonding strength between the existing tiles and the new sintered stone layer.
Step 3: Cleaning the Back of the Sintered Stone Slab
The bonding surface on the back of the sintered stone slab is thoroughly cleaned to remove dust and impurities, ensuring maximum adhesive performance.
Step 4: Tile Adhesive Preparation (For Sintered Stone)
High-performance sintered stone tile adhesive, designed for large-format slabs, is prepared according to technical specifications.
Step 5: Double-Sided Parallel Adhesive Application
Adhesive is applied:
-
On the existing tile surface
-
On the back of the sintered stone slab
Using a parallel troweling method on both sides ensures full coverage and minimizes air pockets.
Step 6: Sintered Stone Slab Installation
The sintered stone slab is precisely positioned and installed over the old tile surface, maintaining correct alignment and joint spacing.
Step 7: Pressing and Vibration Leveling
The slab is pressed and vibrated to:
-
Eliminate trapped air
-
Ensure full adhesive contact
-
Achieve optimal flatness
Step 8: Joint Cleaning and Finishing
Excess adhesive is removed, joints are cleaned, and finishing work is completed to achieve a seamless, refined appearance.
Step 9: Final Inspection and Acceptance
The completed installation is inspected for:
-
Bonding integrity
-
Surface flatness
-
Overall construction quality
Once approved, the renovation is complete.
