MasterSeal 590 – Fast setting mortar to plug active water leaks in concrete and masonry


What is MasterSeal 590?

MasterSeal 590 is a single component hydraulic cement-based, fast-setting, repair mortar that instantly stops running water or active moisture seepage through holes or cracks in concrete or masonry.

Where does MasterSeal 590 work?

MasterSeal 590 is designed to be used:

  • To stop active water or seepage under pressure through joint, static cracks and holes in concrete or masonry, where a normal mortar would be washed away and resin would not bond.

  • As a seal for construction joints or floor joints prior to basement tanking with MasterSeal 581.

  • For scaling cracks and construction joints in reservoirs and other water retaining structures.

  • For instant sewer connections.

  • For rapid anchoring of bolts, conduits, pipes, railings, sanitary equipment, etc.

  • For joint filling and pointing between concrete segments in concrete and brick tunnels, sewage systems, pipes and mines.
