Black Limestone

Black Limestone is a beautiful and durable natural stone. Made of layers of sediment, it is perfect for outdoor use in walkways, patios, and pool areas. Its dark color and texture adds a touch of elegance to any outdoor space. With its natural strength, Black Limestone is low maintenance and long lasting, making it a wise investment for any home or business owner.

Black Limestone Cleaning & Maintenance Solutions

Solution One: Using Stone-Specific Cleaning Products

For general cleaning and stain removal, it is recommended to use stone-specific cleaning agents with a pH of around 10.5.

Steps for Cleaning Black Limestone:

1. Select a Strong Concentrated Cleaning Agent

• This type of cleaner decomposes organic pollution on the surface.
• It also removes surface protective agents effectively.

2. Enhancing Cleaning Power

• If necessary, mix the cleaning agent with detergent powder.
• This prolongs the reaction time and allows the compound to absorb stains into the paste.

3. Perform a Test Patch First

• Apply the solution to a small, inconspicuous area (e.g., a wall corner).
• Ensure that no dark flower marks appear on the limestone surface.

4. Polishing Minor Scratches

• Minor scratches can be removed using polishing powder, available in the market.
• A polishing machine or a single-wiping machine is usually required for effective results.

Solution Two: Using Enzyme-Based Liquid Cleaners

For deeper stains, liquid enzyme cleaners are recommended. These cleaners:

• Penetrate into the bottom layer of the black limestone.
• Extract dirt and dust to the surface.
• Are particularly effective on vegetable stains.

Steps for Deep Cleaning with Enzyme Cleaners:

1. Obtain a Two-Component Enzyme Cleaner

• These are available from high-quality black limestone cleaning agents.

2. For Stubborn Stains, Use a Thickened Paste Method

• Mix the enzyme cleaner with decontamination powder to form a thick paste (similar to peanut butter consistency).
• Apply the paste to the contaminated area.
• Cover it with plastic film and seal the edges with tape.
• Let it sit for 24 to 72 hours.
• Once dried, scrape off the paste using a small bamboo plank.
• Repeat if necessary.

3. Apply a Permeable Protective Agent

• Once the stain is removed, apply a stone protector to prevent future contamination.

Handling Scratches on Black Limestone

• If scratches are present, polishing is necessary.
• The choice of grinding powder depends on the construction party, which may include:
  • Brick soil
  • Cinder
  • Sandpaper
  • Emery
    
• Since the polishing process can be complex, professional handling is recommended.

Special Consideration for Thin Limestone Sheets

• For 305 x 305 x 10mm sheets, high heel damage may penetrate deep into the stone, making it difficult or almost impossible to polish away scratches.
• In such cases, seek expert assistance for proper restoration.
