LITHOS

A breathable, low-viscosity, highly penetrating, and particularly hydrophobic protective treatment containing siloxane oligomers in an aqueous solution. The nanometer-scale diameter of its particles allows the product to penetrate porous materials to a depth that cannot be achieved with standard water-based siloxane protective treatments. The product does not alter the breathability of the substrate and provides high resistance to UV radiation.

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