Repair and Maintenance of Marble Surface Pits

Marble is widely used in architectural decoration for its elegance and beauty, but pits or holes may appear over time. Here are the methods for repairing and maintaining pits on the marble surface:

Repair Methods

1. Deep Cutting

• Perform a 1.5-2CM deep cut on the pit, adjusting the cutting machine for the stone thickness.

2. Vacuum Cleaning

• Thoroughly remove surface dust and debris with vacuum cleaning twice.

3. Moisture Detection

• Detect and record moisture peak values to determine the drying time of the stone.

4. Drying the Stone

• Calculate the drying time based on moisture peak values and use physical methods to dry the stone.

5. Pit Cleaning

• Use physical methods like dry brushing to clean the pit surface, and use chemical cleaning if necessary.

6. Stone Strengthening

• Take measures to improve the loose stone, laying the foundation for later repairs.

7. Stone Patching

• Use special glue (such as epoxy resin glue) and stone powder for patching to ensure full bonding.

8. Rough Grinding to Remove Excess Glue

• Remove excess glue and ensure sufficient water to prevent rapid heat and contraction.

9. Dry the Floor

• Ensure the floor is completely dry.

10. Apply Protection

• Evenly apply high-quality oil-based or water-based protective agents and maintain for 24-48 hours.

11. Neutral Cleaning

• Use neutral cleaners to clean the floor and remove residue from the protective agent.

12. Micro-crack Patching

• Use strengthening agents or filling agents for micro-crack patching.

13. Detailed Grinding and Polishing

• Carry out detailed grinding and polishing of the floor.

14. Crystal Polishing

• Polish the floor with crystal polishing treatment.

15. Enhanced Protection

• If conditions permit, apply a second round of waterproof, oil-proof, and stain-resistant treatment.

Maintenance Methods

• Regular Cleaning: Regularly clean the marble surface with neutral cleaners.

• Avoid Scratches: Avoid wearing high heels or carrying hard objects when walking on the floor.

• Immediate Stain Removal: Clean stains immediately to prevent penetration.

• Regular Protection: Apply protective treatment every six months or once a year.
