Flexseal PS660

Flexseal PS660 is a two-part polysulphide sealant which
when the components are mixed together, cures to form
a flexible rubber seal. It has good adhesion to concrete,
stone, metals and many other common building substrates.

Applications

For sealing structural floor joints in various applications such as:

  • Parapet wall joints.
  • Road and tile joints.
  • Structural Floor Joints.
  • Runway aprons and runways
  • Expansion and construction joints.
  • Joints in metal and concrete sea walls.
  • Joints in water retaining structures (including potable water when using gun grade).
