VERSATILE PIGMENTED EPOXY RESIN FOR HIGH PERFORMANCE FLOOR FINISHES
0.0 (0)
Sikafloor®-264 is a pigmented, two part low viscosity, self-priming (see priming section), epoxy coating / binder used for smooth and textured coatings and/or broadcast overlayments.
- Good chemical and abrasion resistance
- Easily applied with brush, roller and squeegee
- Glossy aesthetic finish
- Slip resistant surface possible
- Durable, impermeable and seamless
- Solvent-free, low odor
- Low mixed viscosity
Usage
Roller coat and self-leveling slurry for concrete surfaces, with medium to heavy duty wear (e.g. storage, hallways, corridors and assembly halls, maintenance workshops, garages and loading ramps), or as a seal coat for broadcast systems. When used as a primer, Sikafloor®-264 can be considered when ≤ 4 % moisture content by mass (pbw – part by weight) is measured on the concrete substrate with a Tramex® CME/CMExpert type concrete moisture meter.Advantages

The use of a different filler other than Sikadur® 504, may change the theoretical coverage rates as displayed above |
MIXING
Mixing Ratio - 2 : 1 by volume.
Each component must be pre-mixed separately to ensure product uniformity.
Primer and Wear Coat:
Premix each component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components for at least 3 minutes using a low speed drill (300–450 rpm) and Exomixer or Jiffy type paddle suited to the volume of the mixing container to minimize entrapped air. Be careful not to introduce any air 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.
Self-leveling Slurry:
Note: If a small mix unit is needed, mix the following quantities: 1 Mixed (A+B) US gal. of Sikafloor 264 plus 11.1 Lbs. of Sikadur 504 type filler. This mix would yield approximately 1.5 gallons of slurry mix.
Premix each component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components for at least 1 minute using a low speed drill (300–450 rpm) and Exomixer or Jiffy type paddle suited to the volume of the mixing container to minimize entrapped air. Add Sikadur 504 type filler and mix for additional 2 minutes. Be careful not to introduce any air while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the slurry. 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 mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.
APPLICATION
Primer
Apply primer by squeegee at the rate of 160–266 ft2 / US gal (3.4–5.4 m2 / L) at 6–10 mils (0.15–0.25 mm) wet film thickness (w.f.t.) and back roll within 15 minutes. Coverage will vary depending on the porosity of the prepared floor. Product has a limited pot life, see Typical Data. Do not apply by dipping roller into mixing container. Pour a bead of product in the form of a ribbon on the surface to be coated, then spread with squeegee and back roll. Ensure that the coating is pore-free and pinholefree and provides uniform and complete coverage over the entire concrete substrate. If necessary, apply an additional coat to ensure the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.
Wear and Sealer Coat
Sikafloor®-264 is applied with a 15–20 mil (0.37–0.5 mm) notched squeegee over a smooth surface and a flat squeegee over a rough or broadcast quartz surface. Back rolling is typically done with an 18 inch (455 mm) wide 3/8 inch (10 mm) nap, solvent-resistant roller cover. Back roll the Sikafloor®-264 only to level the squeegee applied material. Over-rolling and late back rolling may cause bubbling and leave roller marks.
Smooth Finish Self-Leveling Slurry
Pour a bead of product on the surface to be coated, then spread with a notched squeegee or pin rake to the desired thickness (60–120 mils). Roll immediately (within max. 10 minutes of application) in two directions with a spiked roller to ensure even thickness and the removal of entrapped air. To obtain a higher aesthetic finish, spike roll in two directions at a 90 degree angle by passing only once in each direction. The product has a limited pot life, see Typical Data.
