100 - 133 ft² / US gal (2.6 - 3.3 m² / L) at 12 - 16 mils (0.30 – 0.40 mm)

wet film thickness (w.f.t.)

Surface must be clean, sound, dry and primed with appropriate Sikafloor primer. 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. Apply within primer's recoat window.

Mixing Ratio - 2 : 1 by volume.
Each component must be pre-mixed separately to ensure product uniformity.

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 and until uniform 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:
Premix each component separately. If color is desired, the appropriate Sikafloor Epoxy Pigment Pack is added to Component A at a rate of 1 quart (1L) per 2 gallons of Component A. Mix Component A and Sikafloor Epoxy Pigment Pack for 2 minutes and 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 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.

Do not hand mix Sikafloor materials. Mechanically mix only. Do not thin this product. Addition of thinners (e.g. water, solvent, etc.) will slow cure and reduce ultimate properties of this product. Use of thinners will void any applicable Sika warranty. Improper mixing procedure or incorrect mixing ratio may result in moisture sensitivity, whitening, slow cure, soft spots, and other defects.

Sikafloor®-217 is applied with a 12 to 40 mil (0.30 - 1 mm) notched squeegee over a smooth surface and a flat squeegee over a rough decorative quartz or decorative flake surface. Back rolling is typically done with an 18 inch (455 mm) wide 3/8-inch (10 mm) nap, solvent-resistant roller cover. Back-roll the Sikafloor®-217 only to level the squeegee applied material. Over-rolling and late back rolling may cause bubbling and leave roller marks.

• Do not apply while ambient and substrate temperatures are rising, as pinholes may occur. Ensure there is no vapor drive at the time of application. Refer to ASTM D4263, may be used for a visual indication of vapor drive.
• Do not apply in excess of 40 mils in one coat.
• Freshly applied material should be protected from dampness, condensation and water for at least 72 hrs.
• Will discolor over time when exposed to sunlight (UV) and under certain artificial lighting conditions. Use of clear UV resistant top coat may not prevent discoloration of underlying coatings.
• Do not apply Sikafloor to concrete substrate containing aggregates susceptible to ASR (Alkali Silica Reaction) due to risk of natural alkali redistribution below the Sikafloor product after application. If concrete substrate has or is suspected to have ASR (Alkali Silica Reaction) present, do not proceed. Consult with design professional prior to use.
• Any aggregate used with Sikafloor systems must be non-reactive and oven-dried.
• This product is not designed for negative side waterproofing.
• Typically not recommended for exterior slabs on grade where freeze/thaw conditions may exist.
• Use of unvented heaters and certain heat sources may result in defects (e.g. blushing, whitening, debonding, etc.).
• Beware of air flow and changes in air flow. Introduction of dust, debris, and particles, etc. may result in surface imperfections and other defects.
• For professional use only by experienced applicators.
