• During the cleaning procedure, the surface must be protected from water. 
• If required, BERO may be used neat and not to be allowed to dry on the surface.  
• It’s recommended that the surface is treated before installation so that the stone can be flushed with clear water to remove product residues from within the stone.

• Lithofin BERO - 1 LITRE must not be used on polished or fine honed marble, 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 cleaning with Lithofin MN Builder’s Clean.
