Lithofin BERO

Rust Remover and Stone Cleaner

Natural stones often contain traces of iron, which may oxidise when they come in contact with water either through rain or cleaning. The result of this oxidation is that the stone develops rust and discolouration. Lithofin BERO is specifically formulated to remove these blemishes.

Description
Acid based stone cleaner which contains special rust preventing components designed for long-term effect.

Technical Data:
Density: 1.2 g/cm³
pH-Value: <1 (concentrate)
Appearance: clear, yellowish
Odour: odourless
Solubility in Water: very good, complete

Properties
Lithofin BERO chemically changes the rust particles, thereby removing rust discolouration regardless of whether it is a result of the iron in the stone or of environmental influences. Cement residues and similar dirt are also removed.

Field of Use
Lithofin BERO removes rust and rust discolouration and is also suitable for removing cement residues from iron containing natural stones. Suitable for acid resistant hard stones such as serizzo, cresciano, calanca, and for granites such as sardo white, etc. On polished surfaces, the effectiveness of the product is limited. Suitable for indoor and outdoor use.

Directions for Use
Dilute Lithofin BERO up to 1:3 with water depending on the type and stubbornness of the blemish. Apply the solution to the surface and spread it evenly. After approx. 4 to 8 hours, rinse with plenty of clear water. In case of very stubborn rust discolouration, repeat this procedure after several days. During the cleaning procedure, the surface must be protected from water.
Please Note: always test the product in an inconspicuous area prior to use. Lithofin BERO must not be used on polished or fine honed marble and limestone, engineered stone or other acid sensitive surfaces. Enamel, zinc and other acid sensitive materials are attacked by the product. Some natural stones may become slightly darker, this effect will disappear after some time. However, always treat the entire surface to ensure an even appearance. In case of single spots, we recommend Lithofin MN Builder’s Clean.
Coverage: approx. 7 to 15m² depending on the surface.
Advice: iron containing stones should always be cleaned with Lithofin MN Builder’s Clean because this product removes light rust discolouration and prevents them from forming. Should Lithofin CEMENT-AWAY be needed because of extreme dirt deposits, an after treatment with Lithofin BERO may become necessary.

Further Treatment
Treating the surface with Lithofin STAINSTOP >W< will render it resistant to the penetration of water, thereby greatly reducing the risk of dirt accumulation and rust discolouration.

Storage
Keep closed and cool. Shelf life of up to five years.
