Sikafloor®-1610
Sikagard® and Sikalastic® SYSTEMS
Sikafloor®-1610 is a two-component, high solids, low modulus, moisture tolerant epoxy primer that functions as a moisture barrier. This low viscosity resin is highly penetrative, seals substrates, contains a red trace dye to allow coverage to be ensured and is of low VOC content. Sikafloor®-1610 has been formulated to operate as a moisture tolerant adhesion promoter and moisture vapour transmission reduction system beneath Sikafloor®, Sikagard® and Sikalastic® epoxy and urethane coatings, broadcast or trowelled systems.
- Ease of application, low viscosity
- Cured resin resists high moisture (100 % R.H.) and high alkalinity (ph 14)
- Low permeability ~ 0.1 perms at 16 mil d.f.t
- Excellent penetration and stabilization of the cementitious substrates
- High bond strength
- Low tensile modulus
- Meets the requirements of CFIA and USDA for use in food plants

Usage
- Sikafloor®-1610 is suitable for application on new and refurbished interior concrete substrates.
- Designed for application on concrete where Sikafloor®, Sikagard® and Sikalastic® resin systems are due to be installed where a measured moisture content of < 6 % (p.b.w. – part by weight), as determined with Tramex® CM/E meter, and or < 90 % RH (ASTM F2170) in situ R.H. probes conditions exist.
- Sikafloor®-1610 is used in conjunction with Sikafloor®-81 EpoCem®CA to form a permanent moisture barrier on green or hardened concrete with excessive rising moisture > 6 % (p.b.w. – part by weight), as determined with Tramex® CM/E meter and or 100 % R.H. (ASTM F2170) in situ R.H. probes.

MIXING
Mix Ratio: Components A:B = 2:1 (by volume)
For part mixing, i.e. when not mixing full units, each component must be pre-agitated separately to ensure product uniformity.
Pre-stir Components A and B separately, making sure all solids, including trace dye, are evenly distributed and uniform consistencies are achieved within each individual Component. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin) or empty Component A into a suitably sized and clean pail and add Component B in the correct ratio. Blend the combined components thoroughly 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 dimensions of the mixing container and keep the mixing paddle in the mix to minimize entrapped air. Take care 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: Do not try 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® 1610 should be uniform in appearance and consistency.
Important: Mixing attempted at material and ambient temperatures below 18 °C (65 °F) will result in a decrease in product workability. Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.
APPLICATION
Prior to application, measure and confirm substrate moisture content, ambient relative humidity, ambient and surface temperature and dew point. During installation, confirm and record above values at least once every three (3) hours, or more frequently whenever conditions change (e.g. ambient temperature rise/fall, relative humidity increase/decrease, etc.). Moisture content of concrete substrate must not exceed 6 % by mass (pbw – part by weight) as measured with a Tramex® CME/CMExpert concrete moisture meter on the mechanically-prepared surface (see Surface Preparation).
Concrete with Measured Moisture Content < 5 %
Apply one (1) coat of Sikafloor®-1610 with a squeegee at the rate of 4−5 m2/L (160−203 ft2/US gal.) at 8−10 mil wet film thickness and back roll with pressure after 20 minutes. Coverage will vary depending on the porosity and profile of the prepared substrate. Do not apply by dipping roller into mixing container or a paint tray; instead pour a bead of the mixed material, in the form of a ribbon, onto the surface to be coated and then spread with a squeegee and back roll. Ensure that the prime coat is pore- and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.
Concrete with Measured Moisture Content ≥ 5 % - < 6 %
Apply two (2) coats of Sikafloor®-1610 with a squeegee at the rate of 4−5 m2/L (160−203 ft2/US gal.) at 8−10 mil wet film thickness per coat, back rolling both with pressure after 20 minutes. The waiting time between coats will depend upon temperatures but the first coat must be tack-free before the second one is applied, which is typically after 12 hours at 20 °C (68 °F). Do not apply by dipping roller into mixing container or a paint tray; instead pour a bead of the mixed material, in the form of a ribbon, onto the surface to be coated and then spread by squeegee and back roll. Ensure that the second coat is pore- and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.
Concrete with a Measured Moisture Content > 6 %
Apply a minimum 3 mm thick layer of Sikafloor®-81 EpoCem®CA following the application instructions published on the product data sheet. Once cured, apply one (1) or two (2) coats of Sikafloor®-1610 with a squeegee at the rate of 4−5 m2/L (160−203 ft2/US gal.) at 8−10 mil wet film thickness per coat, back rolling both with pressure after 20 minutes. The waiting time between coats will depend upon temperatures but the first coat must be tack-free before the second is applied, which is typically after 12 hours at 20 °C (68 °F). Do not apply by dipping roller into mixing container or a paint tray; instead pour a bead of the mixed material, in the form of a ribbon, onto the surface to be coated and then spread with a squeegee and back roll. Ensure that the second coat is pore- and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.
