Sika® Rugasol®-90

Concrete surface retarder for horizontal surfaces (Summer)

Sika® Rugasol®-90 is a specially formulated liquid surface retarder for summer conditions. Sika® Rugasol®-90 will cause retardation to the surface of the freshly laid concrete, and can be used to achieve an exposed-aggregate type finish. The retarding compound in Sika® Rugasol®-90 combines with cement at the surface and delays the normal hydration on the surface of the concrete (high cement contents and temperatures will reduce the retardation). After retardation has finished, the concrete cures to its full strength.

Sika® Rugasol®-90 can be used undiluted or in diluted version, depending on the degree of the surface penetration required. Depth of penetration is controlled and constant. Surface retardation of up to 24 hours can be achieved. Extremely cost effective.

Consumption

Consumption

Normal exposure up to 20mm ,coverage is 1 litre/4m2 of surface (undiluted Sika® Rugasol®-90).

Normal exposure between 6-10mm, coverage is 1 litre/4m2 of surface (diluted Sika® Rugasol®-90).

Note: Dilution rate should be 1 part water to 1 part Sika® Rugasol®-90. Dilution reduces effectiveness of Sika® Rugasol®-90, trials should occur before application
Application steps

APPLICATION

Sika® Rugasol®-90 should be applied in a good uniform coat onto the horizontal concrete surface as soon as the initial ‘bleeding’ of the concrete has finished but before initial set. (A garden sprayer is suitable).

Treated surface should be protected from direct sunlight or warm wind, which can cause the surface to dry out rapidly. Proper curing procedures are important to ensure the durability and quality of the concrete.

After the initial set of the concrete has elapsed, typically 2-12 hours, depending on concrete type and ambient conditions such as humidity, temperature and wind the soft cement paste on the surface can be brushed off and the exposed aggregate finish washed down with clean water. Whilst  Sika® Rugasol®-90 is in use the concrete surface must be protected from rain, dirt, etc.

Spray equipment should be washed out after use with hot water. Subsequent to removal of paste, proper curing should take place with an efficient curing compound such as Sika Antisol .
