Sika® Rugasol® S

Horizontal Surface Concrete Retardant

  • Chemically delays surface mortar setting to allow time for easy removal of retarded mortar.
  • 3 mm (1/8 in) uniform penetration over surface of entire placement.
  • Aggregate is exposed without being undercut and loosened.
  • Provides high shear resistance and is less costly than chipping, scarifying, hammering, sandblasting or green-cutting.
  • Surface mortar setting is not “killed”, but merely retarded.
