MasterSeal M 689 is used in a variety of waterproofing applications where a high degree of chemical resistance is required. This includes sewage effluent and secondary containment bunds within water the dirty water, chemical and petrochemical industries. MasterSeal M 689 is the most efficient solution for quick waterproofing of surfaces exposed both to mechanical and chemical aggressiveness.

MasterSeal M 689 is applied by means of a suitable two component spray machine. This allows the quick reaction to proceed and ensures a rapid and safe application of the membrane. It sets in few seconds and is fully hardened and operational only after 2 hours. Once hardened, it has high elasticity and crack bridging properties, necessary to avoid water leakages in case of moving cracks in substrates.

MasterSeal M 689 is a continuous membrane with no laps, welds or seams. The membrane shows high chemical / mechanical resistance and can be applied on the harshest environments with high durability.
