Proper surface preparation is crucial for the longevity and appearance of china glazed polish porcelain big slabs. Beyond cleaning and priming, it is important to check the moisture content of the substrate. Excess moisture can lead to adhesive failure and slab detachment. Use a moisture meter to ensure the substrate is dry enough before proceeding.
If the substrate is uneven, consider using a self-leveling compound to create a perfectly flat surface. This step is especially important for large slabs to avoid cracking or uneven adhesion.
A. Dry Laying
- Lay out the china glazed polish porcelain big slabs without adhesive to determine the best arrangement and minimize visible cuts.
- Mark reference lines using a chalk line or laser for alignment.
B. Expansion Joints
- Plan for expansion joints around the perimeter and at intervals to accommodate movement.
Cutting large porcelain slabs requires precision and care. For complex shapes or cutouts, such as around plumbing fixtures or electrical outlets, use a water-cooled diamond blade to prevent overheating and chipping. Always wear protective gear and work in a well-ventilated area.
Consider practicing on a spare slab to perfect your cutting technique before working on the actual pieces.
The double spreading technique not only improves adhesion but also reduces the risk of voids under the slab. When applying adhesive, use a trowel size recommended by the adhesive manufacturer to ensure proper coverage.
For outdoor installations, use adhesives rated for exterior use and consider weather conditions during installation to avoid premature curing or washout.
A. Handling
- Always lift china glazed polish porcelain big slabs with suction cups or slab lifters, and have at least two people handle each slab.
B. Placement
- Carefully position the slab onto the adhesive bed, aligning with your reference lines.
C. Tapping and Leveling
- Tap the slab gently with a rubber mallet or use a tile beater/vibrator starting from the center outward to remove air pockets and ensure full contact.
- Use spacers to maintain even joints (3-5 mm).
- Check the level and flatness with a spirit level.

A. Waiting for Adhesive to Cure
- Allow the adhesive to cure according to the manufacturer's instructions (usually 24 hours).
B. Applying Grout
- Remove spacers and fill joints with suitable grout using a rubber float.
- For minimal joints and color stability, epoxy grout is recommended.
C. Cleaning
- Wipe off excess grout with a damp sponge before it hardens.
- Perform a final cleaning with a soft cloth or diluted acid cleaner if needed.
A. Final Inspection
- Check all joints, edges, and surfaces for uniformity and cleanliness.
B. Sealing (If Required)
- Some polished porcelain slabs may require sealing; consult the manufacturer's recommendations.
C. Protection
- For ongoing construction, cover the installed slabs with protective film or cardboard to prevent damage.
A homeowner installed china glazed polish porcelain big slabs on their kitchen countertop to achieve a sleek, modern look. They followed the recommended surface preparation and adhesive application steps. The slabs were cut precisely to fit around the sink and stove. The result was a durable, stain-resistant surface that enhanced the kitchen's aesthetic.
In a commercial building lobby, large porcelain slabs were chosen for their seamless appearance and durability. The installation team used suction cups and multiple installers to handle the heavy slabs safely. Expansion joints were carefully planned to accommodate building movement. The finished floor received positive feedback for its elegance and ease of maintenance.
- Regularly inspect grout lines for cracks or discoloration and repair promptly to prevent water infiltration.
- Use furniture pads under heavy items to avoid scratching the surface.
- Avoid dragging heavy objects across the slabs to prevent damage.
- Clean regularly with warm water and mild soap.
- Avoid harsh chemicals or abrasive pads.
- For outdoor installations, use gentle power washing if needed.
| Problem | Cause | Solution |
|---|---|---|
| Slabs shifting/moving | Uneven substrate, wrong adhesive, premature traffic | Ensure level base, use correct adhesive, cure fully |
| Poor adhesion | No primer/slurry, wrong adhesive | Always prime, use porcelain-specific adhesive |
| Cracks in slabs | Improper cutting, substrate movement | Use wet saw, allow for expansion joints |
| Grout discoloration | Incorrect cleaning, incompatible grout | Use recommended grout, clean promptly |
| Uneven slabs | Inadequate adhesive coverage or substrate issues | Ensure full adhesive coverage and level substrate |
| Slab chipping | Improper handling or cutting | Use proper tools and handle slabs carefully |
| Grout cracking | Movement in substrate or improper grout mixing | Use flexible grout and allow proper curing time |

Installing china glazed polish porcelain big slabs offers a modern, elegant look with unmatched durability. Success depends on meticulous preparation, the right tools and materials, and careful handling throughout the process. Whether for floors, walls, or countertops, following these steps will help you achieve a flawless, long-lasting installation.
For floors and countertops, 10-20 mm thickness is recommended for durability. For wall cladding, 3-6 mm is often sufficient.
Yes, these slabs are suitable for outdoor use due to their low porosity, UV resistance, and durability. Ensure proper substrate and adhesive for outdoor conditions.
Most glazed porcelain does not require sealing, but some polished finishes may benefit from a penetrating sealer. Always check the manufacturer's guidelines.
Use a wet saw with a diamond blade for straight, clean cuts. For intricate shapes, an angle grinder with a diamond blade can be used.
Apply adhesive to both the substrate and the back of the slab, then tap from the center outward with a tile beater or rubber mallet to remove trapped air.
