Stone impregnation
for Stone Surfaces & Facades

Invisible protection for concrete, natural stone, artificial stone, and mineral plasters/paints
Nanotol for mineral surfaces: Long-lasting protection against dirt, moisture, and aging

The facade is the face of a building—and it deserves special protection. Nanotol nano sealing for mineral surfaces effectively protects stone or plaster facades from moisture, dirt deposits, and environmental influences. The sealant forms an invisible, breathable protective layer that significantly extends the life of the facade – without any visual changes.

Nano Coating for stone surfaces like facades

Nanotol Nanocoating is an invisible, hydrophobic coating for stone facades made of concrete, plaster, or natural stone.
Use Nanotol as a stone surface sealer to prevent water and dirt penetration.
Nanotol can be applied to any stone facade or facade paint that absorbs water. The surface then repels water and dirt but remains permeable to water vapor. The adhesion of dirt particles is reduced, so rain has a self-cleaning effect. Dirt beads off with the rain. The simple application on facade paint has many advantages.
  • Reduces the penetration of moisture and thus moss and mold formation
  • Our eco-friendly nano coating is safe, odorless, and alcohol-free.
  • Cheaper than a facade paint with lotus effect
  • Protects not only the facade paint but also the masonry and the plaster

The product is amazing - unfortunately a bit expensive but very, very good. Impregnates cleanly and without problems.
Works very well! Great product, very easy to use, and great results. I find the price-performance ratio totally acceptable.
Excellent lotus effect on tiles and paving stones!
Will definitely order this again.

Key Benefits of Nanotol Impregnation for Stone Surfaces & Facades

Water and Dirt Repellent

Rain beads off the surface, carrying away dirt thanks to the easy-to-clean effect. Nanotol penetrates deep into the facade paint and coats the pores with nanoparticles.

Affordable & Effective

Compared to a facade paint with lotus effect, Nanotol offers a cost-effective solution—only about 30% of the price—with a lifespan of up to 10 years.

Invisible Finish

This stone surface sealer does not alter the appearance of your facade. It’s a smart, eco-friendly nano coating that preserves the natural look.

Anti-Moss & Anti-Algae Protection

By keeping the surface dry, Nanotol removes the moisture moss and algae need to grow. It’s a reliable anti-moss coating for long-term cleanliness.

Weather & Frost Resistant

The nano sealant for concrete withstands ice, snow, and pressure washing (up to 60 bar) without damage.

Safe & Easy Application

Odorless and alcohol-free, Nanotol is food-safe and requires no protective gear. Just spray and let dry for 24 hours.

How to Test Compatibility with Your Surface

To check if Nanotol is suitable for your facade:

  1. Drip water onto the surface.
  2. If it absorbs the water (even with light pressure), Nanotol will bond effectively.
  3. If water doesn’t absorb, the surface may already be sealed or glazed.

Cleaning a Coated Facade

Once coated, your facade becomes dirt-repellent. Often, a rain shower is enough to clean it. You can also use a garden hose or pressure washer—Nanotol’s coating remains intact.

Advantages of Nanotol facade protection coating

  • Less dirt adhesion on the roof – dirt cannot penetrate the surface and can be easily removed (easy-to-clean effect)
  • Water repellent but vapor permeable (no barrier layer, no trapped moisture)
  • Resistant to pressure washers (roof cleaning with a pressure washer (50–60 bar) is possible without damaging the nanocoating)
  • Reduction of moss/algae formation on the surface (plants lack the necessary moisture to grow)
  • Odorless, no protective equipment needed during application (food-safe, alcohol-free)
  • Weather-resistant (no damage to the stone coating from ice and snow)
  • Reduction of frost damage (water cannot penetrate the coated surface of the roof tile and cause damage during frost)
  • Invisible (no change in appearance)
  • Long-lasting effect – Nanotol Protector (stone coating) is more effective and sustainable than a conventional impregnation
  • Easy to apply (spray on and let dry for 24 hours)

Container Sizes - Nanotol Stone Impregnation

The Protector can be used universally on all open-pored stones or their mineral paint coatings. The only requirement is that water can penetrate so that the nano-impregnation can enter the stone. Depending on the size of the surface to be impregnated, we therefore offer different sizes.

Larger quantities (200 or 1000 L) can be requested directly.

1 Liter

Depending on absorbency, for approximately 20 m²

5 Liter

Depending on absorbency, for approximately100 m²

25 Liter

Depending on absorbency, for approximately 500 m²

Suitable for

  • Roof tiles made of clay or concrete
  • Open-pored stone surfaces
  • Cement, gypsum, plaster
One product for all water-absorbing stone surfaces.

Nanotol coated roof tiles remain like new for longer because dirt is repelled and discolorations are prevented.

Easy to apply

  • No solvents, no odor
  • Spray onto the clean surface
  • Let dry for 24 hours
  • DONE
Coating with the Nanotol Stone Impregnation is quick and easy.

How to Coat Your Facade with Nanotol Stone Impregnation

  • The facade must be clean and free of moss and dust.
  • Then let the stone dry completely.
  • Spray Nanotol Protector for stone surfaces evenly onto the clean surface.
  • Apply two coatings by applying a second layer before the first one dries (wet-on-wet) to cover any missed spots.
  • Let the coating dry and cure for 24 hours. It should not rain during this time.

FAQ

Frequently Asked Questions about Nanotol Nano Coating for Stone Surfaces

There is a simple drop test to try this out:

  • Drip water onto the surface you want to coat
  • Wait to see if the water is absorbed
  • If the water doesn’t absorb on its own, you can apply slight pressure (sponge, cloth, brush)
  • If the surface has absorbed the water, then Nanotol Stone Impregnation can also penetrate and bond. You can coat your surface with Nanotol Protector for stone surfaces.

Nanotol is not suitable if the water could not be absorbed. In that case, there may already be a coating on the surface or the surface is sealed, e.g., glazed, so it cannot absorb water. In this case, Nanotol cannot penetrate and would not work.

Nanotol is only worn off by abrasion. Without abrasion, the effect of the coating lasts at least 10 years. Abrasion occurs through wind and rain. On a side sheltered from the weather, abrasion is lower than on the weather-facing side. Therefore, a general statement about the duration of the effect cannot be made easily.

Nanotol makes the facade dirt-repellent. Therefore, the facade can be cleaned very easily. Usually, a rain shower is enough. You can also use a garden hose or pressure washer. The Nanotol coating is not affected by this.
