These figures are theoretical and does not include for any additional material required due to surface porosity, surface profile, variations in level and wastage etc. Bright color may require additional coat, please conduct trial application to ensure color uniformity surface appearance.

For vertical or wall applications, please conduct a trial application to determine the actual consumption rate based on substrate conditions.
Application steps

MIXING

  • Prior to mixing stir part A and part C separately by mechanically using low speed (100 – 200 rpm) for 30 seconds.
  • Add slowly part C into part A, mix continuously for 30 - 60 seconds until uniform mix has been achieved (this process can be started approximately 1 hour before application to speed up application process).
  • Add part B into mixed part A+C then mix continuously for 2 minutes until a uniform mix has been achieved.
  • Use clean low to medium speed mixer (300-400 rpm) to mix part C into A and mix part B into mixed A+C.
  • Total mixing time is approximately 3 minutes.
  • To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimize air entrainment.
 

APPLICATION

Prior to application, confirm substrate moisture content, r.h. and dew point.

If > 6 % pbw moisture content, Sikafloor® EpoCem® ID may be applied as a T.M.B. (temporary moisture barrier) system.

Primer

Make sure that a continuous, pore free coat covers the substrate. If necessary, apply two priming coats.

Coating

Sikafloor®-2526 W ID is spread evenly by means of a short pile roller or spread by rubber squeegee and back rolling with short pile roller.

A seamless finish can be achieved if a “wet” edge is maintained during application.

CLEANING OF TOOLS

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