A:B = 2:1 by volume

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

Minimum 15 °C (60 °F )   Maximum 30 °C  (85 °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 15 °C (60 °F )   Maximum 30 °C  (85 °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).

Do not apply to concrete substrate with moisture levels > 4 % (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter. 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.

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

Protect from dampness, condensation and water contact during the initial 24 hour cure period.

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

Smooth Coating (23 mil total thickness)

Broadcast Coating (2 mm total thickness)

Note: 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 opacity with light (i.e. white) or bright colours (i.e. reds and yellows) on dark substrates. Test sections are recommended to establish correct coverage.

SURFACE PREPARATION

The surface must be clean, dry and sound. Remove dust, laitance, grease, oil, dirt, curing compounds, impregnations, waxes, foreign particles, coatings and disintegrated particles by any appropriate mechanical means, in order to achieve a profile equivalent to ICRI / CSP 3 - 4. Concrete compressive strength 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 Sikafloor® Fastflor CR application.

Mix Ratio - A:B = 2:1 by volume

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.

Pre-stir each component to ensure all soft settling is dispersed, solids are evenly distributed and even colours and consistencies are achieved within each component. Empty Component A (Resin) in the correct mix ratio into B (Hardener). Mix the combined components for at least three (3) minutes using a low speed drill (300 - 450 rpm) and Exomixer® or Jiffy type paddle suited to the volume of the pail 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.

When completely mixed, Sikafloor® Fastflor CR should be uniform in colour and consistency.  Mix only that quantity you can use within its pot life.

Smooth Coating
Prime Coat: Apply the prime coat onto the substrate using a brush, roller or squeegee, at a uniform coverage without ponding.
Body Coat: Once the prime coat is tack-free, apply the body coat using a squeegee or roller and back roll to achieve even coverage.

    
Broadcast Coating
Prime Coat: Apply the prime coat onto the substrate using a brush, roller or squeegee, at a uniform coverage without ponding.
Broadcast Coat: Once the prime coat is tack-free, apply the broadcast coat onto the substrate using a notched squeegee or trowel. Level out and back roll to achieve an even coverage. Broadcast the selected aggregate (sand size selected for texture) into the broadcast coat to rejection.
Top Coat: Once the broadcast coat has sufficiently cured to allow foot traffic, sweep-up and remove by vacuum any and all loose or un-bonded sand. Apply the top coat using a squeegee, followed by back rolling to provide a uniform texture and finish.

Note: If the Waiting/ Recoat time has passed (refer to Technical Data section) the previous coat must be lightly sanded, to remove all gloss; vacuum cleaning and solvent wiping will be necessary to remove all traces of dust. The surface should be a uniform dullness, with no gloss present after clean-up and before applying the next coat.

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