Sika® Rugasol® S
HORIZONTAL SURFACE CONCRETE RETARDANT
Green liquid, water-soluble, non-flammable, surface retardant for exposed-aggregate concrete. Sika® Rugasol® S is water thin.
- Chemically delays surface mortar setting to allow time for easy removal of retarded mortar
- 3 mm (1/8 in) uniform penetration over surface of entire placement
- Aggregate is exposed without being undercut and loosened
- Provides high shear resistance and is less costly than chipping, scarifying, hammering, sandblasting or green-cutting
- Surface mortar setting is not “killed”, but merely retarded
