The Comprehensive Guide to Silestone Quartz Surfaces

Silestone is a premium brand of quartz surfaces that are used for countertops, flooring, wall cladding, and other interior design applications. Composed mainly of natural quartz, Silestone surfaces are highly durable, stylish, and low maintenance. In this comprehensive guide, we will explore everything you need to know about Silestone quartz, from its composition and manufacturing process to design options, pros and cons, costs, maintenance, and more.

What is Silestone?

Silestone is the market-leading brand of quartz surfaces, manufactured by the Spanish company Cosentino. It is made from 90% natural quartz crystals combined with polyester resins, pigments, and other proprietary compounds. This combination results in a non-porous, highly resilient surface that retains the look and feel of natural stone, while offering greater consistency and durability.

Unlike granite and marble which are mined in quarries as natural stone slabs, Silestone is engineered and manufactured in state-of-the-art production facilities in Spain and the USA. This gives Cosentino much greater control over the aesthetic and performance qualities of the final product. Silestone has become an industry leader, with its surfaces installed in over 100 million properties across the globe since its inception in 1990.

Composition of Silestone

As mentioned above, Silestone derive its unique qualities foremost from its high natural quartz content. Quartz crystals make up over 90% of the material by weight. Here is a breakdown of the other key components:

  • Quartz – Gives surfaces hardness, scratch resistance, and lustrous appearance
  • Polyester Resins – Bind the quartz crystals and provide structural integrity
  • Pigments – Added to achieve different colors and patterns
  • Crystalline particles – Enhance shine and depth of appearance
  • Other Proprietary Compounds – Improve workability, durability and performance

This optimal combination of quartz aggregates and high-tech polymers allows Silestone to offer a tailored balance of aesthetics and functionality for different applications.

How Silestone is Made

Silestone quartz surfaces are made using Bretonstone® technology developed by Breton S.P.A, pioneers in engineered stone manufacturing. The process starts with rigorously inspected raw quartz crystals of precise sizes and high purity. These are combined with the other components outlined above using a high pressure vacuum vibrocompaction process.

The resulting slabs are then cured, precision cut, polished and finished to specifications. State-of-the-art processes ensure minimal variability between batches, delivering consistent quality and appearance.

Here is a brief overview of the manufacturing process:

  • Quartz crystals, resins and pigments precisely measured and blended
  • Mixture compacted under vacuum conditions
  • Slabs produced in specific sizes and thicknesses
  • Computer-controlled cutting for precision
  • Polishing and finishing of surfaces
  • Quality inspections at every stage
  • Packaging and shipping

The dedication to advanced technology and quality control has enabled Silestone to become a top choice for quality quartz surfaces.
