MasterSeal NP 472 has been developed specifically for sealing dynamically moving joints such as expansion and control joints. MasterSeal NP 472 demonstrates high elasticity and recovery properties and therefore may be used to bond and seal most common building materials including concrete, glass, wood, stone, metal and anodised aluminium. In addition MasterSeal NP 472 has excellent tear resistance and good weathering characteristics.
