Rugasol surface retarders have been specifically designed for the production of exposed aggregate finishes or for producing a mechanical key to construction joints, stop ends, or subsequent rendering applications.

Rugasol is normally supplied in two standard grades:

Rugasol F: Low viscosits paste retarder for application to formwork to produce exposed aggregate work.

Rugasol C: Liquid retarder for horizontal construction joints and surfaces.

Rugasol products will only delay the ultimate hardening and do not stop the setting of cement. When used correctly Rugasol will not stain concrete, even white concrete. Rugasol will not affect the bond of reinforcement to concrete even if accidental splashing occurs, provided it is thoroughly cleaned with clean water
