Breathable, low-viscosity, highly penetrating and particularly hydrophobic protective treatment with siloxane oligomers in water solution. The nanometric diameter of its particles allow the product to penetrate porous materials to a depth that cannot be reached with generic water-based siloxane protective treatments. The product does not modify the breathable nature of the substrate, guarantees elevated resistance to UV radiation.

LITHOS is a protectant for natural stone and artifacts of all kinds and nature, unpolished and unpolished lead, plaster, concrete, skim coatings or absorbent mineral finishes. The product does not alter the color appearance of the substrates, making it particularly suitable for protective operations in the conservative restoration of artistic and monumental stones and artifacts and in the protection of exposed masonry. Do not apply to non-absorbent substrates or those previously treated with water-repellent product and not removed.
