Composition and Properties

  • GEMBOND EPDM is used as flexible sealant for concrete joints, and also as a coating for light service areas where some flexibility is required.
  • It has a convenient 1:1 mix ratio.

  • It is ideal for cool stores, pack houses, factory floors, dairy sheds, changing rooms, toilet & shower blocks etc.
  • It can be thinned with acetone and used as a flexible coating on substrates with relatively light traffic where some movement occurs e.g. changing rooms, toilet & shower blocks, plywood floors, plywood decks etc
