What is Silestone N-Boost? (A Simple Explanation of Their Stain Protection)

By Tudor Granite, Worktop Specialist | Updated: October 2025

What does 'N-Boost' actually mean? This technology is a key reason why we recommend Silestone. This article provides a simple, jargon-free explanation of how their N-Boost treatment works at a molecular level to repel liquids, making the surface even more stain-resistant and easier to clean.

What is N-Boost?

N-Boost is not a coating or a sealant. It's a patented treatment applied during the manufacturing process that modifies the surface of the quartz at a molecular level. It works by filling in any nano-pores that may exist on the surface, making it even more uniform and impenetrable than standard quartz.

What Are the Benefits for You?

• Easier Cleaning: Because liquids are repelled, spills can be wiped away effortlessly without leaving a residue.
• Greater Colour Intensity: The treatment enhances the richness and depth of the colour, making it appear more vibrant.
• Improved Shine: N-Boost gives the surface a more brilliant lustre that catches the light beautifully.

Is it a Gimmick?

No. As fitters, we can physically feel the difference. A Silestone slab with N-Boost feels slicker and smoother to the touch compared to quartz without it. For homeowners, it provides an extra layer of confidence against tough stains like red wine and curry.
