Description
Lithofin BERO is an acid based stone cleaner which contains special rust preventing components designed for long-term effect.
Lithofin BERO is specifically formulated to remove the blemishes that natural stones often contain such as 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 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.
Lithofin BERO removes rust and rust discolouration and is also suitable for removing cement residues from iron containing natural stones.
Lithofin BERO is 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.
Lithofin BERO is suitable for indoor and outdoor use.
Technical Data:
Density: 1.2 g/cm³
pH-Value: Appearance: clear, yellowish
Odour: odourless
Solubility in Water: very good, complete
Directions for Use:
Dilute product 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 acids contained in 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 MN Builders Clean.
Coverage: approx. 7 to 15m² depending on the surface. Advice: iron containing stones should always be cleaned with MN Builders Clean because this product removes light rust discolouration and prevents them from forming. Should CEMENT AWAY be needed because of strong dirt deposits, an after treatment with Lithofin BERO is necessary.
Further Treatment:
Impregnating the surface with SPLASH STOP or MN Colour Intensifier 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.
