Pot life is visible. Do not apply after indicated pot life is exceeded.

Before applying second coat, Sikafloor Epoxy or Polyurethane on Sikafloor®-165 FS allow:

160–320 ft² / US gal (3.9–7.8 m² / L) at 5–10 mils (0.13–0.25 mm) wet film thickness.

Surface must be clean, sound and dry. Remove dust, laitance, grease, curing compounds, bond inhibiting impregnations, waxes and any other contaminants. All projections, rough spots, etc. should be removed to achieve a level surface prior to the application.

Concrete should be cleaned and prepared to achieve a laitance-free and contaminant-free, open textured surface by shot blasting or equivalent mechanical means (CSP-3 to CSP-4 as per ICRI guidelines).

Sweep and vacuum any remaining dirt and dust with a wet/dry vacuum. Removing residual dust will help ensure a tenacious bond between the primer and substrate.

Whenever “shot-blasting” is utilized, be careful to leave concrete with a uniform texture. “Over-blasting” will result in reduced coverage rates of the primer and/or subsequent topcoats. The “shotblast” pattern may show through the last coat, known as “tracking”.

The compressive strength of the concrete substrate should be at least 3,625 psi (25 MPa) with a minimum pull off strength of 218 psi (1.5 MPa) in tension at the time of application. For other substrates, please contact Sikafloor Technical Services.

Mixing Ratio - 1.5 : 1 by volume.

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 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 tool 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.

Apply primer/basecoat 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.
