Lithos

Lithos It is a solvent-based deep water repellent. Its use is suitable for both interior and exterior. It protects the stone material for many years, resists UV rays and does not yellow the treated surfaces.

LITHOS is a low viscosity deep water repellent based on silane oligomers mixed with hydrocarbon solvents with high water repellent capacity of penetration into stone materials and for all absorbent building surfaces, such as marble, granite, travertine, natural stone, terracotta, terracotta, agglomerates, grit, cement, both for internal and external use. LITHOS reduces rising damp from the substrate thus avoiding the formation of saline efflorescence on the surface, reduces water absorption, inhibits the formation of borraccia, mould and algae. It repels the adhesion of atmospheric pollution stains, thus allowing easy subsequent cleaning. LITHOS does not alter vapour permeability and allows the treated material good breathability providing the treated surface with excellent resistance to atmospheric agents, sunlight and acid rain. The product does not yellow and lasts for over ten years

Description

HOW TO USE

Dilution: The product is used as received.
Application: Before using LITHOS, it is necessary to carry out a basic cleaning with DETERGON R3 or CLEAN SPECIAL or with SANNY KAL. When the surface is perfectly clean and dry, apply LITHOS with a brush or roller, distributing the product abundantly and evenly in 1/2 coats, 3-4 hours apart. For the continuation of the finish (oil repellent), it is recommended that when using solvent-based products, such as: REP–OIL-NEW, CTF/40, KEOS/928 or KERASTONE, or water-based products such as: IDROBASE 303, they are applied the following day, in 1 or 2 coats, 4-6 hours apart, depending on the absorption power of the support. For any application on vertical surfaces, we recommend the airless spray system, dispensing the product in 2 coats a few hours apart on dry surfaces and outdoors, expect it not to rain for at least 2 days after its application. LITHOS is suitable for application on the back of marble with any cement-based adhesive compatible with the following characteristics: C2ES1; C2TES1; C2ES2; C2TES2. Federchemicals recommends stone suppliers / contractors to verify this compatibility with the glue manufacturer. Therefore, the compatibility between the glue and our impregnating / sealant can only be confirmed by the glue manufacturer.

PRECAUTIONS

Never apply LITHOS water repellent in full sun. Always do a small test sample on a surface to check for any changes in color of the material.

INDICATIVE COVERAGE

Highly absorbent natural stone: approximately 10 to 12 litres per 100 m2 per coat.
Medium porosity natural stone: approximately 5 to 10 litres per 100 m2 per coat.
Cement: approximately 12 to 15 litres per 100 m2 per coat, always depending on the absorption of the type of material.

STORAGE

The product must be stored in the original containers, hermetically sealed, at temperatures between 0 and 25°C, protected from direct sunlight. In these conditions the product has a shelf life of 24 months from the date of the delivery note. If the material has been kept beyond the recommended shelf life, it is not necessarily unusable but a quality control must be performed beforehand on the characteristics relevant to the application.
