MIXING
Mix Ratio - 2 : 1 by volume.
Each component must be pre-mixed separately to ensure product uniformity.
Field Pigmented:
Premix each component separately. If color is desired, the appropriate Sikafloor Epoxy Color Additive-N is added to Component A at a rate of 1 quart per 3 mixed gallons (i.e. Components A+B) for all colors except bright colors like White, Safety Yellow or Tile Red which require 2 quarts per 3 mixed gallons (i.e. Components A+B). Mix Component A and Sikafloor® Epoxy Color Additive-N for 2 minutes or until a uniform color is achieved with a low speed drill (300–450 rpm) and Exomixer or Jiffy type paddle suited to the volume. Empty Component B (Hardener) at the correct mix ratio to Component A (Resin) 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 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:
Premix each component separately. Empty Component B (Hardener) at the correct mix ratio into Component A (Resin). Mix the combined components for at least 2 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. Add Sikadur® 504 type filler and mix for an 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 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 mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.
APPLICATION
Sealer/Intermediate:
Sikafloor®-207 is applied with at 6–16 mils using a 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 (454 mm) wide, 3/8-inch (10 mm) short nap, solvent-resistant roller cover. Back roll the Sikafloor®-207 only to level the squeegee applied material. Over-rolling and late back rolling may cause bubbling and leave roller marks. 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.
Note: Sika does not recommend using Sikafloor®-207 as a receiver coat (clear/pigmented) or a top coat for decorative quartz and flake applications, due to yellowing/ambering, even through full broadcast.
Self-Leveling Slurry:
Pour a bead of product on to the surface to be coated, then spread with a notched squeegee or pin rake between 60–120 mils. Roll immediately (within max. 10 minutes of application) in two directions with a spiked roller and the removal of entrapped air.
