Sika® Rugasol® S
Horizontal Surface Concrete Retardant
- 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.
