Sika® Rugasol® C (NZ)

SURFACE RETARDER TO CREATE AN EXPOSED AGGREGATE FINISH ON FRESHLY LAID CONCRETE

Sika® Rugasol® C (NZ) is an easy to apply product for use on horizontal surfaces of freshly placed concrete with a strength less than 20 MPa. (For concrete strengths greater than 20 MPa, use Sika® Rugasol® C Extra.) It achieves a uniform depth of aggregate exposure to provide a decorative architectural effect and non-slip finish. The retarding compound in Sika® Rugasol® C (NZ) combines with concrete at the surface to delay the normal hydration of cement for a depth of approximately 3 ‐ 6mm.

  • Sika® Rugasol® C (NZ) provides the opportunity for decorative finishes to concrete around the home, civic amenities, commercial buildings, shopping plazas etc.
  • Sika® Rugasol® C (NZ) can be used in conjunction with many different natural aggregates, creating the opportunity for a wide range of colours and texturing effects to be achieved
  • Concrete with an exposed aggregate surface will provide excellent non skid properties, offering a surface that is both decorative and functional
  • Sika® Rugasol® C (NZ) is ideally suited for use on large areas of concrete such as driveways, footpaths and patios to remove the appearance of plain concrete
  • Sika® Rugasol® C (NZ) provides an economical surface preparation to concrete that will be overlaid with a plaster or epoxy screed. This eliminates the need for sandblasting or scabbling

Application steps

APPLICATION

Immediately after the initial bleed water has disappeared from the concrete, and before setting has commenced, Sika® Rugasol® C (NZ) should be applied to the surface using a garden sprayer (or similar). It is essential that a uniform rate of coverage is achieved.

Removal: Sika® Rugasol® C (NZ) will retard the set of the top surface layer of concrete to a depth of approximately 3 ‐ 6mm. It is essential that the soft cement surface be removed before this retardation period has expired, otherwise the surface will be difficult to remove. In order to achieve the desired exposed aggregate finish it is essential that the concrete placer monitors the concrete to determine when the soft surface layer of cement should be removed. The length of the retardation period will vary depending on cement content of the concrete, ambient air temperature, the amount of Sika® Rugasol® C (NZ) applied and the time it is left on the surface before removal. This surface layer should be removed using a hose or low pressure water‐blaster and a soft broom, until a good clean exposed aggregate finish is revealed. As an indication it is normal for the retarding effect of Sika® Rugasol® C (NZ) to be finished after a maximum of 24 hours at 20°C. For temperatures higher than 20°C the retardation period will reduce accordingly. In the summer months it is often necessary to remove the soft surface layer of cement on the same day of concrete placement. Temperatures lower than 20°C may increase the retardation period of Sika® Rugasol® C (NZ).
