Sika® Rugasol® C

Concrete surface retarder for horizontal surfaces

Sika® Rugasol® C is a liquid retarder for horizontal surfaces to exposed aggregate work or for producing a mechanical key to construction joints, stop ends or subsequent screeds applications. The retarding compound in Sika® Rugasol® C combines with cement at the surface and delays the normal hydration for approximately 1-2 days (high cement contents and temperatures will reduce the retardation).  After retardation has finished, the concrete cures to its full strength.

  • Provides the opportunity for decorative finishes to concrete and can be used in conjunction with many different natural aggregates to create opportunity for a wide range of colours and texturing effects
  • Provides and exposed aggregate finish leaving excellent anti-skid properties
  • Leaves an excellent key for further concreting, screeding or rendering
  • Eliminates the need for sandblasting, hacking and brush hammering, leaving the aggregate unbroken and firmly embedded
