Marble vs. Quartz Aggregate Epoxy Flooring: Which is Better?


Epoxy mixed with stone aggregate makes an extremely durable floor coating. The type of natural stone used can determine the overall success of the floors performance over time.

As a company that has used both, we know, through research and development as well as years of experience, that quartz is a superior stone when crushed and mixed with epoxy for back-of-house flooring. Here’s a breakdown.


a non-foliated metamorphic rock that forms when limestone is subjected to heat and pressure; composed primarily of the mineral calcite (

marble is usually light-colored (white, gray, pink, yellow, bluish, or black)

Marble retains limestone-like characteristics when it is crushed. The aggregate forms irregular chipped shapes. 


3 on the Mohs hardness scale


cheaper than quartz


lower hardness rating meaning if epoxy wears off it will be more susceptible to wear, stains, and it is more porous than quartz; darkens with age


a ubiquitous mineral with an enormous number of uses (



quartz occurs in virtually every color; common occurrences: brown, clear, white, gray, purple, yellow, black, pink, green, red


7 on the Mohs hardness scale


20%-40% more expensive than marble


very hard stone; chemical, stain, and heat resistant; yellows with direct sunlight; 

Summarily, marble is a softer stone than quartz and if subjected to extensive wear-and-tear will be more susceptible to corrosion resulting in visible wear and failure over time. As marble is more porous, there is greater potential for stains and bacteria growth. 

If considering an epoxy and quartz flooring system, be sure to choose one that is 100% quartz as opposed to a blend of marble. Also, consider a monolithic layer system instead of a broadcast which would be significantly more susceptible to failure, delamination, and erosion.
