Key Takeaways
- Chlorine and Flash chemically destroy marble surface through an acid reaction that dissolves calcium.
- Crystal polishing is a chemical reaction forming a permanent glass-like layer, not just wax.
- Graded diamond pads (400-800-1500) must be used to remove the damaged layer.
- Preventive maintenance with pH-neutral cleaner weekly preserves shine for years.
- Re-polishing costs 80% less than completely replacing the marble.
Have you noticed that the marble floors in your home have lost their original shine? Has the surface become rough and dull despite frequent cleaning? If you're using cleaners like "Flash" or chlorine, you're unfortunately destroying your marble without knowing it. In this comprehensive guide, we'll explain the scientific reason behind this problem and the ultimate solution to restore your floors' beauty.
What is Marble and Its Chemical Composition?
Marble is a metamorphic rock primarily composed of Calcium Carbonate (CaCO₃), the same material found in eggshells and chalk. This chemical composition makes it a beautiful, shiny stone, but it also makes it extremely sensitive to acids.
When calcium carbonate is exposed to any acidic substance, an immediate chemical reaction occurs resulting in partial surface dissolution. This reaction is scientifically called "Acid Etching", and it's the main reason marble loses its shine.
Why Flash and Chlorine Destroy Marble?
Most common household cleaners in Saudi Arabia, such as Flash, chlorine, and even vinegar, contain strong acids. When you use these materials on marble, the following happens:
- Chemical Reaction: The acid dissolves a thin layer of the marble surface
- Microscopic Etching: Thousands of tiny invisible pits form
- Light Scattering: The rough surface scatters light instead of reflecting it
- Shine Loss: Marble appears dull and faded
- Dirt Accumulation: Small pits trap dust and stains

How to Know If Your Marble Is Damaged?
There are several clear signs that your home's marble has been acid etched:
- Surface feels rough when touched with fingertips
- Stains don't disappear even with deep cleaning
- Circular dull spots (from juice or coffee spills)
- Varying degrees of shine across different areas
- Floor no longer reflects light or images as before
The Ultimate Solution: Diamond Grinding and Crystal Polishing
Applying wax or surface polishes is not enough to fix damaged marble. The only solution is marble resurfacing using diamond grinding followed by crystal polishing.
Phase One: Diamond Pad Grinding
We use professional grinding machines with graduated diamond pads:
- Grit 400 (Coarse): Removes damaged layer and deep scratches
- Grit 800 (Medium): Smooths surface and removes coarse grinding marks
- Grit 1500 (Fine): Prepares for final stage
- Grit 3000 (Super Fine): Achieves glass-smooth surface
Phase Two: Crystallization
This is the magic step! We use a special crystalline material that chemically reacts with the calcium carbonate in marble to form a hard glass-like layer called Calcium Fluorosilicate. This layer:
- 3 times harder than original marble
- Scratch and erosion resistant
- Reflects 95% of light
- Lasts for years with proper maintenance
Marble Polishing Cost in Saudi Arabia
Costs vary depending on marble condition and work area, but generally:
| Service Type | Price (SAR/m²) |
|---|---|
| Light Polish (Maintenance) | 15 - 25 SAR |
| Grinding + Polish (Moderate Damage) | 35 - 50 SAR |
| Deep Grinding + Crystal (Severe Damage) | 60 - 80 SAR |
Tips to Maintain Your Marble After Polishing
- Use pH-neutral cleaner: Avoid any acidic or strong alkaline cleaners
- Wipe spills immediately: Especially juices, coffee, and vinegar
- Place doormats at entrances: To prevent sand and gravel entry
- Use pads under furniture: To prevent scratches
- Schedule maintenance every 6-12 months: To preserve shine
