Polyurea WCS

Fosroc Polyurea WCS is a cartridge-packed, 100% solids, flexible, two-component, rapid curing Pure Polyurea system available in two grades.

Standard grade is low pressure spray or pour-applied, designed as a waterproofing and protective coating for small areas including repair work. It combines the advantages of seamless coating with long life cycle and high durability.

Gun Grade is a thixotropic version, designed as an excellent seam seal for the Fosroc Proofex Engage waterproofing system.
