Sikafloor®-220 W Conductive must be applied and distributed immediately after mixing.
*Do not apply after indicated Pot Life is exceeded. End of Pot Life is not visible.

Before applying Sikafloor ESD on Sikafloor®-220 W Conductive allow:

4 to 6 mils wet film thickness per coat, at 401 ft² to 267 ft² (37 m² to 25 m²) per gallon (3.78 L). Product will not cure properly if applied at excessive thickness.

Mix Full units only
Premix each component separately. Empty Component B into Component A container. Mix both components thoroughly for 3 min using a low-speed drill (300–400 rpm) to minimize entrapping air. Use an Exomixer or Jiffy type mixing paddle (recommended models). During the mixing operation scrape down the sides and bottom of the pail with a flat or straight edge trowel at least once to ensure thorough mixing. Upon completion of mixing, Sikafloor 220W Conductive should be a uniform color.

Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature. Sikafloor®-220 W Conductive must be placed and distributed on the application surface immediately after mixing.

Note: Only start application of Sikafloor®-220 W Conductive after the overall priming coat has dried tack-free. Otherwise there is a risk of wrinkling or impairing of the conductive properties. Electrodes must be installed before the application of Sikafloor®-220 W Conductive.

The floor should be divided into sections (at expansion joints or doorways when possible) that can be completed without stopping. When ending a section, tape it off to form a clean edge for an adjacent section. The Sikafloor®-220 W Conductive must be applied with a 3/8” nap roller and roller trays. 18 inch roller assemblies and trays are preferred. The roller should be wet in the tray and then the excess coating is removed by lightly rolling in the tray so as to avoid drips. Then apply 3 pairs of 6 - 8 foot long paths on to the floor. Then spread the material with roller passes perpendicular to the paths of coating. It is extremely important to apply the coating at a rate of 4 - 6 mils to achieve proper appearance,
texture, and color development, and consistent ESD properties. If areas are too thick, the coating may be too soft, if too thin, the coating will appear very flat in sheen and may exhibit poor electrical properties. Work evenly to avoid late “tie-in” and re-rolling to adjacent previously applied material; Doing so may result in color variations.

When Sikafloor®-220 W Conductive primer is used in conjuction with Sikafloor 200C ESD/Sikafloor 700C ESD, test the primed surface for conductivity prior to the application of Sikafloor 200C ESD. A value of < 10 X 10³ ohms per ANSI/ESD S7.1/ASTM F-150 must be achieved.

CAUTION: Excessive application thickness will result in “skinning over” which will result in soft, uncured product on the floor and unacceptable conductivity readings. Do not exceed recommended application thickness. Beware of pockets, “bug holes” or other depressions in the concrete surface where Sikafloor 220W may accumulate during application. Examine cured Sikafloor 220W surface for non-uniform appearance which may indicate areas where the product was applied in excessive thickness. These must be removed, prepared again and recoated prior to application of the top coat. Properly applied Sikafloor 220W primer will exhibit a uniform dull black finish.

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