Sika Rugasol MH Vertical Exposed Aggregate Retarder – 10L

Sika Rugasol MH is a surface retarder designed specifically for exposing vertical surfaces. Rugasol MH is supplied as a gel and is designed to be applied to the face of formwork prior to placing concrete. The depth of retardation depends on the thickness of the coating, the time elapsed before the retarder is removed, the cement content and the quantity of water in the mix. Depending on the ambient conditions, Rugasol will retard the surface for up to 3 days giving the concrete plenty of time to setup before the formwork is removed.
