Before applying Sikalastic®-823 / Sikalastic®-825 allow:

¹⁾ Assuming that dirt has been removed properly and contamination is avoided

~1.33 kg/m²/mm

Prior to mixing stir part A mechanically. When all of part B is added to part A mix continuously for 3 minutes until a uniform mix has been achieved. To ensure thorough mixing pour material in a clean container and mix again to achieve consistent mixOver mixing must be avoided to minimise air entrapment.

Sikalastic®-822 is poured and then spread evenly with a notched / toothed trowel. Roll immediately in cross wise with a spiked roller to ensure even thickness andto remove any entrapped air.

Clean all tools and application equipment with Thinner C immediately after use.Hardened and/or cured material can only be removed mechanically.
