Sikafloor®-422

6 month in unopened container

Store dry between 40 °F and 90 °F (4–32 °C).

60 % ± 1.0

Please consult Sikafloor Technical Services.

Do not apply after indicated Pot Life is exceeded. End of Pot Life is not visible.

Before applying second coat of Sikafloor®-422 allow:

* If the recoat window exceeded, the floor surface should be screened using 80–100 grit, to the effect that the gloss is removed before applying the next coat.

320–533 ft²/ US gal (7.9–13.1 m²/ L) at 3.0–5.0 mils/ coat (0.075 –0.125 mm) wet film thickness (w.f.t.). Recommended 2 coats over a primed surface.

Mix full units only

Clear Resin: 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.

Field Pigmented: If color is desired, the appropriate Sikafloor Polyurethane Color Additive is added to Component A at a rate of 1 quart per 3.8 mixed gal. (i.e. Components A+B). Mix Component A and Sikafloor Polyurethane Color Additive for 2 minutes or until a uniform color is achieved with a low speed drill (300–450 rpm) and Exomixer or Jiffy type paddle suited to the volume. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin) and mix for additional 2 minutes. 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 operations, 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

Pour a thin bead (approximately 6–12 in. wide) of Sikafloor®-422 on the surface, use a flat squeegee to distribute the material evenly and back roll. Back roll the Sikafloor®-422 only to level the thickness of material applied. Do not apply in excess of 6 mils (0.15 mm) WFT, failure of the coating may occur. Divide the floor into sections (at expansion joints or doorways when possible) that can be completed without stopping. Where a section will end, it should be taped off to form a straight line providing a clean edge for an adjacent section. Back rolling is typically done with an 18 in. (455 mm) wide short nap, 3/8 in. (10 mm), solvent-resistant roller cover. Over-rolling and late back rolling may cause bubbling and leave roller marks.
