When tinting on site:
Add 1 x 946 ml Sikafloor® Epoxy Pigment Pack CA into part 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 and during the application.
Ambient Air Temperature
Minimum: 10 °C (50 °F) Maximum: 30 °C (86 °F)
Note: Mixing carried out under conditions where the Sikafloor®-219 UTE temperature and ambient temperature are below 18°C (65°F) will result in reduced product workability and slower curing 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 (86 °F)
Note: Mixing and application attempted at material, ambient and /or substrate temperature conditions less than 18 °C (65 °F) will result in an increase of the viscosity of the Sikafloor®-219 UTE and slower cure rates.
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).
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 |
Note:
- 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 72 hours following the end of the application.
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 |
IMPORTANT: If the maximum waiting time has been exceeded. The previous coat must be lightly sanded, to remove all gloss; vacuum cleaning using a brush attachment followed promptly with a solvent wipe off the surface as per the following generally accepted practices:
- Avoid using solvent that can leave a oily residue: (such as, but not limited to most mineral spirit).
- Avoid Paper Towels: Pre-treated shop towels or standard paper towels may contain silicone or manufacturing additives that will ruin your paint job. Stick to lint-free cotton cloths or dedicated microfiber towels.
- Change Rags Frequently: As soon as a rag becomes visibly dirty, discard it or fold it to a clean side. Continuing to wipe with a saturated, dirty rag just re-deposits contaminants onto the surface.
- Wet Wipe: Pour a solvent (onto the first rag. Do not dip the rag into the solvent container; pour it directly to keep your supply clean).
- Lift: Wipe down a small, manageable section (e.g., ~0.5 m2 [~ 4-6 ft2]) of the surface. Use enough pressure to break up and lift the oils or sanding dust. Rotate the cloth frequently so you are always using a clean spot.
- Dry Wipe: Before the solvent can flash off (evaporate) and dry on the surface, wipe the same section with a second, clean, lint-free rag. When used correctly, this second cloth absorbs residual solvent and removes materials that could reduce or prevent adhesion or the proper performance of the next coat.
Consumption
Smooth Coating: (23 mil total thickness)
As a primer: (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)
IMPORTANT:
- Do not hand mix Sikafloor® materials; mechanically mix only.
- Sikafloor®-219 UTE must be applied as supplied.
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.
Field Pigmented using Sikafloor® Epoxy Pigment Pack CA: Pre-stir 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.
Note: Prepare only the amount that can be applied within the open time (i.e., during the pot life) and at the actual job site temperature.
APPLICATION
As a primer: 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.
Waiting Time / Overcoating:
It is important to apply subsequent coats of this and other products within 48 hours (under normal curing conditions). If this coating is allowed to cure longer than the 48 hours before subsequent recoats. Refer to the Waiting Time / Overcoating on page 3 of this document for preparing the surface.
CLEAN UP
Clean all tools and equipment with a non-flammable solvent. Once hardened, product can only be removed mechanically.
