FLEXICLAD PC® is a two component, 100% solids, trowelable elastomeric polymer composite that has been specifically formulated to seal vertical expansion joints in concrete as well as other cementitious / mineral substrates including tiles, brick, slate, stone, etc. It also bonds very well to metal and wood surfaces.

FLEXICLAD PC requires no primer, bonds to most rigid substrates and cures at ambient temperatures. It has been specifically designed to resist countless freeze / thaw cycles – stretching to well over 600%. It is excellent for sealing between dissimilar materials which may expand and contract at different rates. It also has very good chemical resistance making it the ideal choice for use in secondary containment areas as well as walls in production areas, loading docks, etc.

FLEXICLAD PC incorporates revolutionary polyaspartic technology for sealing expansion joints where durability and flexibility are uniquely important:

  • Secondary Containment Areas
  • Bulk Transfer Areas
  • Production Room Walls
  • Loading Dock Walls
  • Vertical Joints On Roof Decks
  • Wide Joint Seals
