Surface Retarders

Permacolour Surface Retarders are solutions of chemicals which react with cement in the concrete surface and retards the set of the surface layer to a depth of between 3mm and 12mm while the underlying concrete sets. This enables the concrete surface to be removed easily, often by brushing or waterblasting and exposes the aggregate to give the depth of the etch to the concrete.

These retarders come in two forms:
  • Perma-Colour Surface Retarder  - Maximum strength of concrete - 20MPA
  • Perma-Colour Surface Retarder Extra - For concrete strengths over 20MPA
