Crystalline / Capillary

MasterSeal® 530 (formerly known as MasterSeal 530 FC)

Fast curing surface applied capillary waterproofer for concrete and mortar


MasterSeal 530 fast curing consists of a blend of moisture-activated chemicals, high-grade silica aggregates and selected cements. It waterproofs through the formation and development of crystals in water bearing capillaries and interstices, effectively blocks the further passage of water and ensures permanent water tightness of the structure.

MasterSeal 530 application on vertical construction and day work joints RECOMMENDED USES
MasterSeal 530 is recommended for areas such as:
 Static construction joints (new construction)
 Water tanks and towers, reservoirs, dams,
 Water treatment works, harbours
 Concrete pipes, sumps, foundations
 Retaining walls, lift shafts
 Sea defence walls, bridge decks, jetties,
 Fast curing membrane for internal wet area




  • Forms crystals in concrete pores - Waterproofs by becoming an integral part of the structure. Active ingredients will not delaminate, peel off or wear away.

  •  Vapour permeable -Allows surface to breathe, preventing build up of vapour pressure.

  • Brushable consistency - Easy to apply by brush or spray.

  • Unrestricted application - Effective against both positive and negative water pressure.

  • One component - Economical to use.
