- The retarding compound in Sika® Rugasol C combines with cement at the surface and delays the normal hydration on the surface of the concrete (high cement contents and temperatures will reduce the retardation).
- After retardation has finished, the concrete cures to its full strength.
- Sika® Rugasol C can provide decorative finishes to concrete and can be used in conjunction with many natural aggregates.
- It can provide an exposed aggregate finish leaving excellent anti-skid properties.
- Sika® Rugasol C leaves an excellent key for further concreting, screeding or rendering.
Sika® Rugasol C is a liquid retarder for horizontal construction joints and surfaces for use in cooler conditions or low retardation conditions. Sika® Rugasol C is an easy to use, economical product applied to obtain a mechanical key for “kicker” joints, renderings and screeds on horizontal surfaces of freshly placed concrete.
