Usage

Sikafloor®-2570 WB is designed as a primer for Sikafloor epoxy and urethane coatings, as well as for broadcast and troweled systems. When used as a primer Sikafloor®-2570 WB can be considered where ≤ 6 % moisture content by mass (pbw – part by weight) is measured on concrete substrate with Tramex® CME/CMExpert type concrete moisture meter (refer to Limitations).

wet film thickness.

Application steps

MIXING

Mixing Ratio - 1 : 1 by volume.
For bulk packaging, when not mixing full units, each component must be pre-mixed separately to ensure product uniformity.

Primer
Premix each component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components for at least 3 minutes using a low speed drill (300–450 rpm) and Exomixer or Jiffy type paddle suited to the volume of the mixing container to minimize entrapped air. Be careful not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.
Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.

APPLICATION

Primer/Sealer:
Apply primer by squeegee at the rate of 160–320 ft² / US gal. (3.9–7.8 m²/ L) at 5–10 mils (0.13–0.25 mm) wet film thickness (w.f.t.) and back-roll with pressure. Coverage will vary depending on the porosity of the prepared floor. Product has a limited pot life, see Typical Data. Do not apply by dipping roller into mixing container. Pour a bead of product in the form of a ribbon on the surface to be coated, then spread with squeegee and back roll. Ensure that the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate. If necessary, apply an additional coat to ensure the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.
