~500 cps (A+B Mixed /Clear)

~28 g/L

Minimum ~0 °C (~32 °F)   Maximum ~50 °C (~122 °F)

Condition product at temperatures between 18 °C and 30 °C (65 °F and 86 °F) before using.

Minimum: 10 °C (50 °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. 

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 (85 °F) 

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.

Moisture content of concrete substrate must be ≤ 4 % by mass (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 % by mass (pbw – part by weight) as measured with Tramex® CME / CMExpert type concrete moisture meter, use Sikafloor®-1610 or Sikafloor®-81 EpoCem®CA.

ASTM F2170 internal probe testing is not a substitute for measuring substrate moisture content with a Tramex® CME / CMExpert type concrete moisture meter as described above.  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.

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

Freshly applied material should be protected from dampness, condensation and water for at least 24 hours.

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

Note: If the Waiting/ Recoat time has passed 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.

Smooth Coating: (23 mil total thickness)

Prime coat: (8 mil) 5 m²/L (203 ft²/US gal.)

Wear coat: (15 mil) 2.6 m²/L (106 ft²/US gal)

Note: Actual coverage rates and material consumption will depend upon porosity and profile of substrates. 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 matter, coatings and detritus from the surface by appropriate mechanical means, in order to achieve a profile equivalent to ICRI / CSP 3 - 4 for floors and ICRI / CSP 1 - 3 for walls. The compressive strength of the concrete substrate 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®-219 UTE

Mixing Ratio - A:B = 2:1 by volume

For bulk packaging, when not mixing full units, each component must be pre-mixed seperately to ensure product uniformity.  Do not hand mix Sikafloor® materials. Mechanically mix only.  

Mix only that quanitity which can be used within its pot life at actual field temperature.

Clear Resin: Premix each Component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components 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 volume of the mixing container to minimize air entrapment. 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.

Sikafloor® UTE Colour Pak Pigmented:  Premix each component seperately, including the Sikafloor® UTE Colour Pak to ensure product uniformity. For all colours, add one (1) 500 ml (16.9 oz) Sikafloor® UTE Colour Pak for every 3.78 L (1 US gal.) of Component A resin and mix at low speed (300 - 450 rpm) for three (3) minutes until a uniform colour is achieved using a drill fitted with an Exomixer® or Jiffy type paddle.  Be careful not to introduce any air bubbles during the mixing process.   Empty Component B (Hardener) in the correct mix ratio to Component A (Resin) and mix for additional three (3) 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 operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing. 

NOTE: When using brighter colours, additional coats may be required. Using more color additive than recommended will result in extended cure times and reduced chemical and abrasion resistance.

Prime Coat: Apply Sikafloor®-219 UTE as a prime coat onto the substrate using a brush, roller or squeegee, at a uniform coverage without puddling.

Wear Coat:  Once the prime coat is tack-free, apply the wear coat using a squeegee or roller and backroll to achieve even coverage. 

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 with Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically.
