Marble is beautiful—but it’s not indestructible. Whether it’s on your floor, wall, or countertop, over time, cracks can appear in marble due to wear, heavy foot traffic, or the natural settling of buildings. These cracks don’t just take away from the beauty of the stone—they can also trap dirt, moisture, and bacteria, making them worse over time.
The good news? You don’t need to replace your marble. At NPSM Specialized Cleaning Services, we offer a complete marble restoration service that includes crack repair using mastic filler, full grinding, polishing, and sealing—bringing your marble back to life.
Let’s walk you through how we professionally repair cracks in marble and why mastic filler and our step-by-step restoration process are the best solutions.
Why Do Cracks Form in Marble?
Before jumping into the repair process, let’s understand why cracks appear:
Impact from heavy objects
Natural shifting or settling of structures
Moisture infiltration
Improper installation or uneven subfloor
Lack of maintenance or sealing
While some cracks are surface-level, others may go deeper. That’s why our marble restoration service isn’t just about patching cracks—it’s about bringing the whole surface back to a uniform, polished, and sealed condition.
Our Marble Restoration Process (Including Crack Repair)
We don’t just fix the crack—we restore the entire surface so the repair blends in seamlessly and your marble shines like new again.
We start by grinding the marble surface using diamond abrasive pads. This step helps to:
Level uneven tiles (lippage)
Remove minor scratches and dull spots
Open up hairline cracks for proper filling
Expose the raw surface for better adhesion
This grinding process gives us a clean, smooth base to work on.
2. Grouting & Crack Filling with Mastic Filler
Once the surface is prepared, we begin grouting and filling the cracks and any visible holes using mastic glue—a professional-grade filler specifically designed for natural stone like marble.
Why mastic?
It bonds well with marble
Can be color-matched for a seamless look
Long-lasting and non-yellowing
Flexible enough to move with minor shifts in the surface
We use high-quality mastic that’s either pre-mixed or tinted to match the exact shade of your marble, ensuring the repair blends in naturally.
3. Second Phase of Grinding
After filling and curing, we perform a second round of grinding. This step ensures:
The mastic filler is flush with the marble surface
Any remaining scratches or filler residue is removed
The surface is prepped for a high-gloss finish
This double-grinding technique is key to making sure your marble surface looks uniform and perfectly level.
4. Powder Polishing with Surfactant
Next, we apply a special marble polishing powder combined with a surfactant. This polishing compound reacts with the marble surface to:
Restore natural shine
Enhance color depth
Smooth out minor imperfections
Leave a glossy, elegant finish
We use polishing machines equipped with soft pads that glide over the surface, slowly revealing the natural sheen of the marble.
5. Rinsing with Neutral Stone Soap
After polishing, we carefully rinse the surface using a pH-neutral stone soap. This removes:
Residual polishing powder
Surface dust and mastic particles
Any oil or debris left from the polishing stage
Neutral cleaners are important because harsh chemicals can damage marble and strip away its natural finish.
6. Buffing with White Pad
Once cleaned, we buff the surface using a soft white pad. This step:
Emphasizes the natural veins and color
Enhances the final shine
Smooths out any remaining unevenness
Gives the surface a fresh, finished look
Buffing is what gives marble that luxurious “hotel lobby” shine that everyone loves.
7. Applying Marble Sealer
Finally, we apply a high-quality stone sealer to protect the surface. This seals the grout, the repaired cracks, and the entire marble surface, preventing:
Stains from liquids
Moisture intrusion
Dust and dirt build
Discoloration over time
Sealing is one of the most important steps and is often skipped in DIY repairs. But with Dubai’s climate and foot traffic, sealing helps your repair last longer.
Many people ask, “Should I use epoxy?” But for marble crack repair, we specifically use mastic glue because:
It’s designed for natural stone
It’s easier to sand and polish
It blends better with the marble’s texture
It stays flexible, reducing the risk of future cracks
Unlike epoxy, mastic is forgiving, especially during polishing. It becomes part of the surface rather than sitting on top of it.
Common Questions About Marble Crack Repair
Q1: Will the crack still be visible after repair? If color-matched and polished correctly, cracks are nearly invisible after restoration.
Q2: Can I fix marble cracks on my own? Small hairline cracks might be DIY-able, but full repairs require grinding, filling, polishing, and sealing—best done by professionals.
Q3: How long does the full restoration take? A standard villa or commercial floor takes about 1 to 2 days, depending on area and crack severity.
Q4: How long does the repair last? With proper sealing and maintenance, our crack repairs last for years—even under heavy foot traffic.
Don’t Just Patch It—Restore It Properly
Fixing a marble crack isn’t just about filling the line. It’s about restoring the entire surface so it shines, protects, and lasts.
At NPSM Specialized Cleaning Services, we don’t believe in shortcuts. Our full marble restoration process ensures that once we’ve repaired your marble, it looks and feels brand new—no mismatched patches, no dull spots.
