Artificial stone disease treatment methods

Shanghai Jiani Material Technology Co., Ltd. is a professional company specializing in the production of stone tiles.

Even with protective treatment, artificial stone will develop various defects due to natural aging. The frequent defects include whitening, yellow stains, oil contamination, cement slurry residue, mortar residue, rust spots and miscellaneous stains.

- Whitening: Tiny crystalline white specks occasionally appear on some dark-colored artificial stone, resembling the efflorescence of natural stone from a distance.

- Yellow stains: Caused by contamination from straw ropes, cardboard, timber, or chemical reactions between cement and internal components of artificial stone.

- Oil contamination: Penetration of vegetable oil, engine oil, hydraulic oil on and inside artificial stone.

- Cement & mortar residue: Dried cement and mortar dirt adhering to the stone surface.

- Rust spots: Oxidation stains formed by iron substances on artificial stone.

- Miscellaneous stains: Contamination from cola, tea, soy sauce and other daily condiments & beverages.

2. Remediation Methods for Common Artificial Stone Defects

Specialized stone cleaners shall be adopted for different stone defects, and all cleaning work must be performed by professional stone maintenance contractors.

Remediation Process for Yellow Stains, Oil Contamination & Miscellaneous Stains

1. Rinse dust and debris off the artificial stone surface with clean water;

2. Apply stone cleaner evenly and thoroughly;

3. Cover the surface with soft cloth to allow sufficient chemical reaction;

4. Rinse the surface completely with clean water;

5. Fully air-dry the stone;

6. Apply protective sealer.

Remediation for Whitening

Coat the affected area with our exclusive color enhancer to eliminate whitening effectively.

Remediation Process for Cement & Mortar Residue

1. Apply specialized cleaner evenly;

2. Let it react fully until the mixed solution changes color;

3. Scrub and rinse the surface thoroughly with clean water;

4. Fully air-dry the stone;

5. Apply protective sealer.

3. Precautions for Artificial Stone Defect Remediation

1. If the cleaner is acidic or weakly acidic, consult the stone manufacturer and professional maintenance company before use on artificial stone.

2. Cleaning is meant to remove surface dirt, coatings and dust. The stone must be completely dried prior to applying cleaner.

3. For optimal cleaning results: After coating cleaner, cover the surface with paper towels or cotton cloth, reapply cleaner over the covering material, and seal with plastic film to isolate air exposure.

4. Conduct a small-area test patch before full-scale construction; only proceed if the test delivers satisfactory results.

5. After cleaning and thorough drying, protective sealing treatment is mandatory.

4. Post-Remediation Protective Treatment for Artificial Stone

Protective sealing must be implemented immediately after removing all stone defects to prevent re-contamination within a short period.
