B1 700 is a protective, solvent-based, stain-proof treatment fast drying and specifically formulated to not alter the appearance of the materials on which it is applied in any way, leaving the surface with high stain-proof performance. The product is particularly recommended on all surfaces that are sensitive to colour changes following the application of an impregnating agent.
Due to these characteristics, B1 700 is a great solution for treating natural stone, such as limestone, which are generally difficult to protect due to changes in colour. It's quick and easy to apply, it doesn't create any film and therefore, it does not change the original breathability of the treated surface. It's UV resistant, it won't end up yellowing over time and is suitable for use indoors and outdoors.
