Whether you are looking to clean or protect, our StoneSeal™ nanocoating solution is ready to help rejuvenate stone and mineral-based products throughout your home. Prevent unsightly scale build-up on your concrete fountain, eliminate staining on your brick patio, and enjoy a soot-free fireplace both indoors and out. Our StoneSeal™ solution is specifically designed to prevent grime and weathering on mineral-based porous surfaces and to maintain their appearance for years to come. This solution can be used on terracotta rooftops to prevent typical wear and tear over time, saving future maintenance and cleaning costs down the road. Also consider using on your mineral-based pool decks, flooring, kitchen counters, art pieces, and more.

This product is invisible to the eye and will not damage your stone or mineral-based surfaces. It’s designed to seal and protect from water and salt absorption, as well as environmental damage caused by UV and heat. This coating will protect against discoloration and stains, as well as prevent mold and mildew growth.

StoneSeal™ is eco-friendly, biodegradable, and is comprised of more than 75% renewable, raw materials. It provides outstanding resistance towards water, liquids, stains, oil, and grease; and protects the surface from scratching, marring and fading. Our StoneSeal™ coatings is water-based and non-toxic, making them easy to work with and family-friendly.

Application & Storage

  • Surface Preparation: Ensure a clean, dry surface before application.
  • Application: Spray on the surface and let it dry.
  • Dry/cure time: This coating completely adheres to the surface after 24 hours. The coating will only exhibit the hydrophobic property after this curing period.
  • Coverage: 30-200 mL/m2 depending on the absorbency of the substrate.
  • Storage: 2-year unopened shelf life. (3°C to 30°C).



Stone & Porous is a water-based, non-toxic, and eco-friendly hydrophobic and oleophobic stone nanocoating.

It is breathable and virtually invisible to the human eye at a thickness of 100-150 nm.

Stone & Porous can be applied onto a dry, clean surface by means of using a spray bottle.

After 24 hours, the coating will have cured completely and will fully adhere to the surface and exhibit hydrophobicity.

Stone & Porous can be applied to any type of porous surface with a mineral-based origin, including concrete, limestone, sandstone, concrete blocks, porous granite/marble, and roof tiles/clay terracotta.

Stone & Porous binds to the surface at a molecular level to greatly increase the lifespan of surfaces while preventing weathering and grime buildup.

30-200 mL per m2  (depending on absorbency of the material).

Stone & Porous is water, contamination, chemical, and abrasion resistant as well as UV stable. It is also resistant to temperature change.

Stone & Porous has a shelf-life of 2 years (unopened) when stored at a temperature between 3ºC to 30ºC
