Application steps

EQUIPMENT

Mixing Tools
Sikafloor®-220 W Conductive must be thoroughly mixed using a low speed electric stirrer (300–400 rpm) or other suitable equipment.

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

Application of Sikafloor® conductive primer:
Uniformly spread 1 × Sikafloor®-220 W Conductive using a short pile nylon roller (12 mm).

CLEANING OF EQUIPMENT

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