When tinting on site:
Add 1 x 946 ml Sikafloor® Epoxy Pigment Pack CA into part the A (7.57 L)of Sikafloor®-219 UTE for the standard format.
Add 2 x 946 ml Sikafloor® Epoxy Pigment Pack CA into part A (18.9 L) of Sikafloor®-219 UTE for the medium format.
Product Temperature
Condition product at temperatures between 18 °C and 30 °C (65 °F and 86 °F) before using.
Ambient Air Temperature
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.
Relative Air Humidity
Maximum 85 % (during application and curing).
Dew Point
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.
Substrate 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.
Substrate Moisture Content
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®-1620 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 substrates are conducted per ASTM F2170 for project-specific requirements, values must be ≤ 85 %. If values exceed 85 %, according to ASTM F2170, use Sikafloor®-1620 or Sikafloor®-81 EpoCem®CA.
Pot Life
~25 minutes
Curing Time
| Ambient & Substrate Temperature | Foot Traffic | Light Traffic | Normal Traffic |
| 10 °C (50 °F) | ~48 hours | ~4 days | ~7 days |
| 23 °C (73 °F) | ~24 hours | ~2 days | ~5 days |
| 30 °C (86 °F) | ~16 hours | ~36 hours | ~4 days |
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.
Waiting Time / Overcoating
| Ambient & Substrate Temperature | Minimum | Maximum |
| 10 °C (50 °F) | ~48 hours | ~96 hours |
| 23 °C (73 °F) | ~24 hours | ~48 hours |
| 30 °C (86 °F) | ~16 hours | ~36 hours |
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.
Consumption
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 the porosity and the profile of the substrate. Test sections are recommended to establish correct coverage.
SUBSTRATE QUALITY
Concrete surfaces must be clean and sound. The compressive strength of the concrete substrate should be at least 25 MPa (3625 psi) at 28 days and a minimum of 1.5 MPa (217 psi) in tensile strength, at the time of the application.
Substrates must be free of contaminants such as dust, dirt, existing paint films, efflorescence, exudates, laitance, form, hydraulic or fuel oils, brake fluid, grease, fungi, mildew, biological residues or any other contaminants which may prohibit good bond or conditions of the substrate that may reduce the overall performances of Sikafloor®-219 UTE.
MIXING
Mix Ratio: A:B 2:1 by volume. Do not hand mix Sikafloor®-219 UTE materials. Mechanically mix only.
Clear Resin (for both standard and medium formats): Pre-mix each component separately. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin). Mix the combined components for at least three (3) minutes, using a low-speed drill (300 - 450 rpm) to minimize entrapping air. Use an Exomixer® or Jiffy type mixing paddle (recommended model) suited to the volume of the mixing container. 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 attempt to attend to unmixed material that may gather on the sides of the mixing container while mechanical or electrical parts are in motion. When completely mixed, Sikafloor®-219 UTE should be uniform in colour and consistency.
Sikafloor® Epoxy Pigment Pack CA: Premix each component separately, including the content of the Sikafloor® Epoxy Pigment Pack CA to ensure product uniformity. For all colours, add one (1) 946 ml Sikafloor®-219 UTE for every 7.56 L (2 US gal.) of Component A (Resin) for the standard format. For all colours, add two (2) 946 ml Sikafloor®-219 UTE for every 18.9 L (5 US gal.) of Component A (Resin) for the medium format. 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 an 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. Do not attempt to attend to unmixed material that may gather on the sides of the mixing container while mechanical or electrical parts are in motion.When completely mixed, Sikafloor®-219 UTE should be uniform in colour and consistency.
Immediately discharge the product and place material on the substrate to be coated. Mix subsequent batches immediately.
APPLICATION
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 UP
Clean all tools and equipment with a non-flammable solvent. Once hardened, product can only be removed mechanically.
