under "Important Considerations".

Condition products between 18 °C to 24 °C (65 °F to 75 °F)

Minimum 10 °C (50 °F)   Maximum 30 °C (86 °F)

Maximum 85% (during application and curing)

Substrate must be at least 3 °C (5 °F) above the dew point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature.

Minimum 10 °C (50 °F)   Maximum 30 °C (86 °F).

Mixing and application attempted at material, ambient and/or substrate temperature conditions less than 18 °C (65 °F) will result in a decrease in product workability and slower cure rates.

Moisture content of concrete substrate must be < 4 % (pbw – part by weight) as measured with a Tramex® CME/CMExpert type concrete moisture meter on mechanically-prepared surface according to this product data sheet (preparation to ICRI / CSP 3 - 4).  If moisture content of concrete substrate exceeds 4 % (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter, use Sikafloor®-1610 or Sikafloor®-81 EpoCem®CA or Sikafloor® 22NA or 24 NA PurCem®.

When relative humidity tests for concrete substrate are conducted per ASTM F2170 for project specific requirements, values must be ≤ 85 %. If values exceed 85 % according to ASTM F2170, use Sikafloor®-1610 or Sikafloor®-81 EpoCem®CA or Sikafloor® 22NA or 24 NA PurCem®.  ASTM F2170 testing is not a substitute for measuring substrate moisture content with a Tramex® CME/CMExpert type concrete moisture meter as described above.

Do not apply while ambient and substrate temperatures are rising, as pinholes may occur. Ensure there is no vapour drive at the time of application. Refer to ASTM D4263, may be used for a visual indication of vapour drive.

Users should refer to the most recent individual resin component product data sheet for specific "Pot Life" information by product.

Users should refer to the most recent individual resin component product data sheet for specific "Cure Time" and "Waiting Time to Overcoating"      information by product.

Final system "ready for use" cure times above are for a double broadcast system using component products detailed under the "Consumption" section of this product data sheet.

Curing times will vary according to air and substrate temperatures and relative humidity. 

Freshly applied material should be protected from dampness, condensation and water for at least 72 hours.

Mechanical, chemical and physical properties will be fully achieved at full cure.

Actual coverage rates and material consumption will depend upon porosity and profile of substrates.  Allowance must be also made for variation in film thickness or number of coats required to achieve complete coverage of surfaces. Test sections are recommended to establish correct coverage.

The concrete surface must be clean and sound. Remove any dust, laitance, grease, oil, dirt, curing agents, impregnations, wax, foreign matters, coatings and deleterious material from the surface by any appropriate mechanical means, in order to achieve a profile equivalent to ICRI-CSP 3-4. The compressive strength of the concrete should be at least 25 MPa (3625 psi) at 28 days and at least 1.5 MPa (218 psi) in tension at the time of application of Sikafloor®-156CA prime coat.

Do not hand mix Sikafloor® materials. Mechanically mix only.
Pre-stir Components A and B separately, making sure all solids, are evenly distributed and uniform consistencies are achieved within each individual Component. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin) or empty Component A into a suitably sized and clean pail and add Component B in the correct ratio. Blend the combined components thoroughly at low speed (300 - 450 rpm) for at least three (3) minutes using a drill fitted with an Exomixer® or Jiffy type paddle suited to the dimensions of the mixing container. Keep the mixing paddle in the mix to minimize entrapped air. Take care 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.  Upon completion of mixing, Sikafloor®-156CA / Sikafloor®-2002 or Sikafloor®-217 should be uniform in colour and consistency.

Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.

Primer: Apply neat Sikafloor®-156CA over the prepared concrete slab as a primer using a brush, roller, or squeegee at a uniform coverage without ponding. Allow primer to cure sufficiently to be able to resist foot traffic without damaging the surface.

1st Broadcast: When the primer coat has cured sufficiently to allow foot traffic, apply a neat broadcast binder coat of Sikafloor®-156CA by squeegee and backroll immediately with a roller to provide a uniform surface. Broadcast pre-blended Sikafloor® Broadcast Quartz Aggregates into the wet Sikafloor®-156CA binder, to “saturation”. Broadcast in a manner so that the aggregate falls vertically into the binder. Allow the 1st broadcast layer to cure sufficiently to be able to resist foot traffic, without damaging the surface, before proceeding with the second broadcast application.

2nd Broadcast: Remove excess aggregates from the 1st broadcast layer by sweeping up, followed by vacuuming until the surface is free of all loose particles and dust.  When necessary, lightly abrade the surface to remove imperfections after sweeping up aggregate and before final vacuuming. Apply a neat broadcast binder coat of Sikafloor®-156CA using a squeegee and backroll immediately with a roller to provide a uniform surface. Broadcast preblended Sikafloor® Broadcast Quartz Aggregates into the wet binder to “rejection”. Broadcast in a manner so that aggregate falls vertically into the binder. Allow the 2nd broadcast layer to cure sufficiently to be able to resist foot traffic, without damaging the surface, before proceeding with the top coat.

Topcoat: Remove excess aggregates from the 2nd broadcast layer by sweeping up, followed by vacuuming until the surface is free of all loose particles and dust. Note: When necessary, lightly abrade the surface to remove imperfections after sweeping up aggregate and before final vacuuming. Apply Sikafloor®-2002 or Sikafloor®-217 topcoat using a non-marking squeegee or flexible steel trowel, followed by backrolling to provide a uniform texture and gloss finish.

Note: The final surface texture and glossy appearance of the finished floor is highly dependent upon the specific application rate of the Sikafloor®-2002 or Sikafloor®-217 topcoat. Application at 10 mils will produce a medium texture with good gloss; application at 20 mils will produce a fine texture with a high gloss appearance.

Optional Topcoats: Can be applied to change the surface sheen and improve long term UV resistance to colour change; Sikafloor®-317 UV will produce a matte appearance, Sikafloor® 315 and Sikafloor® 942 will produce a high-gloss finish. 

Sika Canada strongly recommends that a test area be applied to confirm specific top coat selection and application rates required to produce the desired final appearance.

Clean all tools and equipment with Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically.
