Before applying solvent free products on Sikafloor®-160 allow:

Applied over relatively smooth concrete floors. Rough, worn or pitted concrete floors will require additional material.

Mixing Ratio - 2 : 1 by volume.

For bulk packaging, when not mixing full units, each component must be pre-mixed separately to ensure product uniformity.
Note: If a small mix unit is needed, mix the following quantities: 64 oz of Component A (Resin) + 32 oz of Component B (Hardener) + 1 bag of Sikadur Trowel Aggregate (50 lbs). This mix would yield approximately 22 ft² at 1/4” (6 mm).

Clear Resin
Premix each component separately to ensure product uniformity. Empty Component B (Hardener) in 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. Be careful not to introduce any air bubbles while mixing. 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. Transfer the mixed binder (components A+B) into a suitable mechanical mixer. Gradually add aggregate (Component C) to the binder. Once all ingredients are combined, mix continuously and thoroughly for 2 to 4 minutes to ensure complete mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the mortar. Immediately transfer the materials onto the floor or into a screed box for application.

Field Pigmented
Premix each component separately to ensure product uniformity. If color is desired, the appropriate Sikafloor® Epoxy Pigment Pack is added to Component A at a rate of 1 quart per 5 gallons of Component A. Additional Sikafloor® Epoxy Pigment Packs may be necessary. Mix Component A and Sikafloor® Epoxy Pigment Pack for 30 seconds 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) in the correct mix ratio to Component A (Resin) and mix for additional 2 minutes. Be careful not to introduce any air bubbles while mixing. 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. Transfer the mixed binder (components A+B) into a suitable mechanical mixer. Gradually add aggregates (Component C) to the binder.

Once all ingredients are combined, mix continuously and thoroughly for 2 to 4 minutes to ensure complete mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the mortar. Immediately transfer the materials onto the floor or into the screed box for application.

Note: The color of the installed Sikafloor®-160 may vary in shades, due to the high consumption of natural aggregates and/or different finishing techniques like power or hand troweling.
Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.

Mortar Application
Maintain all control joints and expansion joints through the screed where movement is expected. Place mortar onto the still uncured primed surface while still tacky or fully cured primer with 20 mesh quartz sand and spread using a steel trowel, gauge rake or if using a screed box, pull the box across the wet primer overlapping approximately 1 inch. The hand troweled or screed box applied material can then be power troweled. The power trowel will compact the material, remove voids and make the floor smooth and dense. (Excessive power troweling will cause blisters.) The finished surface should be relatively smooth, free of trowel marks and without any process areas. Finish using a clean steel finishing trowel or power trowel. Whenever Sikafloor®-160 does not abut a vertical surface, the mixed product should be troweled into a chase which is a special groove cut into the concrete floor during the preparation process. Areas around drains and elevation changes or terminations must maintain a minimum 1⁄4 in (6 mm) thickness. Sikafloor®-160 has a wet consistency. To finish areas inaccessible to a power trowel, use light “feathering” strokes with a hand trowel to smooth the surface. When Sikafloor®-160 has cured, the surface should be lightly ground or sanded to remove any burrs or surface defects then sweep and vacuum.

Grout and Sealer Application
Grouting and sealing of Sikafloor®-160 may be required. The following Sikafloor® products may be used, Sikafloor®-264, Sikafloor®-217 Thixo Lite or 264 Thixo Lite.
