Analysis of Five Common Causes of Sintered Stone Detachment and Prevention Methods

Detachment of sintered stone is a common issue that can lead to severe property damage and safety hazards. Here are five common causes of sintered stone detachment and corresponding prevention methods:

Substrate Internal Separation

• Cause: The substrate is not sturdy and may be experiencing sand loss.

• Solution: Remove loose substrate and level with cement mortar before proceeding to the next construction step.

Separation of Waterproof Layer from Substrate

• Causes:

  • The selected materials do not meet standard requirements and lack sufficient bonding strength.

  • The substrate does not meet requirements, such as being uneven, dirty, cracked, or sandy.

• Solutions:

  • Choose materials that meet national standards.

  • Check the substrate before construction to ensure it is clean, smooth, and free of cracks and sand.

  • Treat the substrate as needed, such as repairing cracks and using primer to enhance bonding strength.

Internal Rupture of the Waterproof Layer

• Causes:

  • The waterproof material has quality issues.

  • The wrong type of waterproof material is chosen, such as the improper use of rigid and flexible materials.

  • The substrate is overly dry.

• Solutions:

  • Choose the appropriate waterproof material.

  • Ensure the substrate is moist before construction.

  • Use suitable materials to adapt to different substrate conditions.

Detachment of Tile Adhesive from Waterproof Layer

• Causes:

  • The tile adhesive does not meet bonding strength requirements.

  • Improper cement mortar ratio.

• Solutions:

  • Choose high-quality tile adhesive.

  • Ensure the correct cement mortar ratio.

Detachment of Sintered Stone from Tile Adhesive

• Causes:

  • The tile adhesive is not suitable for sintered stone.

  • The back of the sintered stone is not cleaned properly, and there is mold release agent residue.

• Solutions:

  • Choose tile adhesive suitable for sintered stone.

  • Clean the back of the sintered stone before installation to ensure no mold release agent remains.

Conclusion

The issue of sintered stone detachment requires a comprehensive consideration of material selection, substrate treatment, construction methods, and other factors. The correct choice of materials and standardized construction processes are key to preventing sintered stone detachment. Adequate preparation and inspection before construction, the use of appropriate materials, and ensuring construction quality can effectively prevent the problem of sintered stone detachment.
