Sika® Rugasol®-2 W Liquid is compatible with Sika® concrete admixtures.  Where high dosage rates of retarder or accelerator are to be used in the concrete mixture it is advisable to conduct site trials. A precondition for achieving an acceptable exposed aggregate finish is to have satisfactory concrete quality especially with regard to granulometry of aggregates and good placing and compaction procedures.  Site trials are recommended to establish consumption requirements to achieve the required effect especially in variable ambient temperatures.

0,1–0,2 kg/m² depending on dilution rate and absorbency of formwork. Consumption depends on dilution rate and absorbency of the substrate. These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

Dilute with clean water at a ratio of 1:1 to 3:1 depending on required effect.

Horizontal surfaces of freshly cast concrete

Allow the surface water of the newly laid concrete to evaporate for between ½ to 2 hours depending on ambient conditions. Apply Sika® Rugasol®-2 W Liquid with brush, roller or spray equipment. Ensure an even coverage to give a consistent retardation depth of the concrete surface.  Once the main concrete has gained sufficient strength to withstand the cleaning process wash off the weak concrete surface layer carefully with a water jet and if necessary using a suitable brush.

Wooden formwork

Only apply to thoroughly clean formwork. Apply by brush, roller or spray equipment. Concreting must be within 48 hours of the Sika® Rugasol®-2 W Liquid application. After casting concrete, strike formwork as quickly as possible and wash concrete surfaces with a water jet, if necessary using a suitable brush.
