Application

Application Information

Mixing Ratio

Part A : Part B = 1 : 1 (by weight)

Ambient Air Temperature

+8°C min. / +35°C max.

Relative Air Humidity

75% r.h. max.

Dew Point

Beware of condensation!

The substrate must be at least 3˚C above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature

Substrate Temperature

+8°C min. / +35°C max.

Substrate Moisture Content

< 6% moisture content. 

Test method: Sika® Tramex meter, CM - measurement or Oven-dry-method.

No rising moisture according to ASTM (Polyethylene-sheet).

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile ,variations in level and wastage etc.
Application steps

MIXING

Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 2 minutes until a uniform mix has been achieved.

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, relative humidity and dew point. 

If > 6% pbw moisture content, Sikagard®-720 EpoCem® may be applied as a T.M.B. (temporary moisture barrier) system.

Primer: Make sure that a continuous, pore free coat covers the substrate. Apply the Sikafloor® primer by brush or roller. 

Wall coating: Apply Sikagard®-67 by roller.

CLEANING OF TOOLS

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