KOSTER BD 50 is a ready-for-use, solvent-free and easy to spread sealing compound for waterproofing surfaces under tile and/or coverings in damp and wet rooms. Once applied to the substrate, it cures to a highly flexible, waterproof synthetic membrane which is highly elastic and crack-bridging. All customary solvent-free tile adhesives may be applied on top of KOSTER BD 50. The tile may be laid in mortar or using the thick-bed or the standard thin-bed method.
