Quartz comprise over 93% natural quartz, which is hard, strong, and resistant to scratch, shock and compression and 7% of pigments and resins.
The prescribed mixture results in a product that is non-porous, exceedingly durable, and more than twice as strong as granite. Moreover, it is durable and maintenance-free, resistant to heat, staining and acid damage.
Quartz stone owes its inherent gloss to the natural sheen of quartz. It does not require additional polishing and maintains its shine and smooth structure for long years. The gloss of the surface is measured with a gloss-meter denoting the percentage of light reflected from the surface.
Surface finishing
Quartz stone is available in a choice of three main finishes; polished, matte and sandblasted.
How to clean quartz tops
In order for polished Quartz stone surfaces to maintain the first day shine for long years, a neutral detergent soluble in water would suffice for a simple and periodic cleaning. Yet, remember to use all the detergents and cleaning agents in amounts as instructed by the producers and rinse thoroughly with water after treatment. Otherwise, any residual cleaning agents that would accumulate on the surface may chemically harm the surface in the long run causing a dirty and dingy appearance.
