Sika® Rugasol® MH is a surface retarder used mainly for on site exposed aggregate work. Sika® Rugasol® MH surface retarder is used to expose aggregate on formed Portland cement based concrete surfaces, both vertical and horizontal.
Sika® Rugasol® MH dries on the formwork to form a tough, water-insoluble, abrasion resistant film. It is not affected by light foot traffic or by light showers. Forms may be coated before or after erection. Reinforcing steel is placed as usual. The depth of retardation depends upon the thickness of the coating, the time elapsed before the retarder is removed, the cement content and the quantity of water in the mix. The ambient temperature will also affect the depth of retardation.
