Operating manualProduct sheet

BNL7 is a stone sealer for masonry facades based on silanes/siloxanes and high-quality additives. After use, the product is invisible, highly water-repellent and remarkably durable. BNL7 belongs to the latest generation of stone sealers. It reacts with the substrate at the micro level and bonds closely to mineral substrates. It penetrates deep into porous brickwork and forms a highly hydrophobic, weather-resistant seal. BNL7 is based on a unique formula that repels moisture very quickly once dry.
