    SikaSet® NC is an effective accelerator where high early strength concrete is desired and the use of calcium chloride is prohibited.

    SikaSet® NC may be used to accelerate set times and increase early strength gain where job-site efficiency is important in order to meet construction deadlines. SikaSet® NC saves time and money by allowing faster finishing and stripping of concrete surfaces. Accelerated setting time across a wide range of temperatures. Increased early and ultimate ...

    Add the correct amount of SikaSet® NC at the concrete plant. The admixture may be added manually or by automated dispenser directly in the mixer or into the water line at the batch plant. When used in combination with other admixtures care must be taken to dispense each admixture separately into the mix. Do not mix with dry cement. Field evaluation...

    Results may differ based upon statistical variations depending upon mixing methods and equipment, temperature, application methods, test methods, actual site conditions and curing conditions.

  5. Apply Sikalastic® HLM 5000 S when substrates are dry and air temperatures are 40 to 90 °F (4 to 32 °C); for application at temperatures below 40 °F (4 °C), consult Technical Services. Temperatures influence the viscosity and handling characteristics of Sikalastic® HLM 5000 S: heat increases and cold decreases the flow.

  6. If more than one layer of fabric is required, apply additional Sikadur®-330 at a rate of 100 ft2/gal. (2.37 m2/L) and repeat as described above. This equates to a thickness of approximately 16 mils. Add a final layer of Sikadur®-330 onto the exposed surface at a rate of 160 ft2/gal. (3.79 m2/L).
