Understanding Quartz Tiles: How They Differ from Marble and What to Expect When Polishing

Quartz, a versatile material in tiling, comes in various forms with distinct properties and applications.

What is Quartz?

People often confuse these types of quartz due to their similar names and appearances. The main distinctions lie in their composition (natural vs. engineered), porosity, durability, and polishing capabilities. Understanding these differences is crucial when choosing the right type of quartz for a project.

Quartz is a widely used material in the tile industry, but there are different types of quartz-based tiles that often cause confusion. Here are the main types and how they differ:

Terrazzo Quartz

  • Composition: Made from crushed quartz, marble, glass, or other glittery aggregates set in a cement or resin matrix. Resin quartz is usually cut into smaller tiles, often confused as being marble. Terrazzo floors are usually poured directly on the floor or into a mould for countertops, forming whole sheets rather than smaller tiles.
  • Appearance: Speckled with visible chips, sometimes with glittery or glass-like flecks.

 

Engineered Quartz

  • Composition: A man-made tile mostly used for countertops.
  • Appearance: Available in various colours and patterns, often mimicking natural stone but with marbled patterns.

Quartzite

  • Composition: A natural metamorphic rock formed from sandstone and silicon dioxide, exposed to heat and pressure. Quartzite has fewer limestone shells than marble but quartz can still etched by acidic spillages. 
  • Appearance: Usually has a leathery, textured surface which may have clear or white non-reflective quartz crystals. Quartzite has fewer crystalline features than gneiss, which is compressed granite.

So, which of these Quartz Tiles can be polished like marble?

If you’re looking to polish quartz-based tiles like marble, it depends on the type of quartz and its composition. Here’s how each type reacts to polishing:

Can Be Polished Like Marble

✅ Quartzite Tiles (Natural Stone)

  • Polishability: Yes, quartzite can be honed and polished similarly to marble. It can achieve a glossy or honed finish with the right polishing techniques.
  • Process: Requires diamond polishing pads and sealing afterward since it’s porous.
  • Consideration: Some quartzite is harder than marble, making it more challenging to polish.

✅ Cement-Based Terrazzo Quartz Tiles

  • Polishability: Yes, cement-based terrazzo can be polished like marble using grinding and diamond polishing techniques.
  • Process: Similar to marble restoration—grind the surface, polish it with finer abrasives, and seal it.
  • Consideration: Requires maintenance and sealing due to its porous nature.

Cannot Be Polished Like Marble

❌ Resin-Based Terrazzo Quartz Tiles

  • Why Not? The resin component limits how much polishing can be done. Over-polishing can burn the surface or create uneven gloss levels.
  • Alternative: Light buffing or resealing rather than full grinding and polishing.

❌ Engineered Quartz Tiles (Quartz Composite Tiles)

  • Why Not? The resins make it resistant to polishing. Unlike natural stone, polishing won’t remove scratches or restore shine in the same way.
  • Alternative: Use specialized cleaners or mild buffing with non-abrasive compounds.

❌ Sparkly Quartz Tiles (Resin-Bonded)

  • Why Not? These tiles are factory-finished with a resin coating, and aggressive polishing can damage the finish or reduce the sparkle effect.
  • Alternative: Clean with a pH-neutral cleaner and buff lightly if needed.

Conclusion

If you want true polishability like marble, choose natural quartzite or cement-based terrazzo. Resin-based quartz tiles and engineered quartz do not respond well to traditional polishing methods and may require alternative maintenance solutions.
