Consumption
As a primer, applied at 4 - 6 wet mil vertically. For cove application, applied at approximately 4 lin.m/L (50 lin. ft. /US gal) with specified aggregates at 3mm (1/8") thick at 100 mm (4") high. Coverage rates are calculated based on material needed for finishing of smooth surfaces.
MIXING
Mixing Ratio: 3: 1 by volume plus approximately 5-7 kg of the aforementioned Sikafloor-Decorative® Quartz and Sikafloor® Aggregate PT per 1 L of mixed Sikafloor®-293.
Mix the combined components for at least three (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 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.
Transfer the mixed binder (components A+B) into a suitable mechanical mixer. Gradually add specified aggregates aggregates (component C) to the binder. Once all ingredients are combined, mix continuously and thoroughly for two (2) to four (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 where the cove is to be installed.
Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.
APPLICATION
The use of a low level light along the floor/wall intersection will show shadows and aide in reducing trowel marks or ridges. After thoroughly mixing, immediately deliver material along the floor/wall. Apply the material by striking it up the wall with a steel trowel or margin trowel, ensure the thickness is consistent. Keep the trowel clean by wiping with a rag dampened with solvent. The solvent will act as a lubricant to assist in troweling, do not use water. Finish with a cove trowel.
