Sikafloor®-261 Fast Set
SMOOTH FINISH COATING (20 - 30 MIL)
Sikafloor®-261 Fast Set is a two-component, rapid curing, solid colour, high solids, silicone-free, low-viscosity, self-priming, glossy epoxy resin available in an unlimited colour range. Typically installed as a seamless, high build, smooth coating for light to medium duty traffic areas. This general service epoxy coating demonstrates good mechanical and chemical resistance. Final surface appearance options include: unlimited colour selection, integral cove base, gloss, satin or matte surface sheen. Sikafloor®-261 Fast Set can also be used as a resin component (primer, binder and top coat) for high performance Sikafloor® Morritex Systems.

Application
Mixing Ratio
A:B = 2:1 by volume
Product Temperature
Condition product at temperatures between 18 and 30 °C (65 and 86 °F) before using.
Ambient Air Temperature
Minimum / Maximum: 10 / 30 °C (50 / 85 °F).
Mixing and application attempted at material, ambient and/or substrate temperature conditions less than 18 °C (65 °F) will result in a decrease in product workability and slower cure rates.
Relative Air Humidity
Maximum 85 % (during application and curing).
Dew Point
Substrate must be at least 3 ˚C (5 ˚F) above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish.
Substrate Moisture Content
Moisture content of concrete substrate must be ≤ 4 % by mass (pbw – part by weight) as measured with a Tramex®CME / CMExpert type concrete moisture meter.

Consumption
Floor
Prime coat: 5 - 8 m2/L (200 - 325 ft2/US gal.) at 5 - 8 mil w.f.t.
Wear coat: 1.6 - 3.3 m2/L (65 - 135 ft2/US gal.) at 12 - 25 mil w.f.t.
Refresher coat: Apply at the same rate as wear coat
Wall and Ceiling
Prime coat: 8 m2/L (325 ft2/US gal.) at 5 mil w.f.t.
Finish coat: 2 x 8 m2/L (325 ft2/US gal./coat) at 2 x 5 mil w.f.t.
(Addition of Sikafloor® Extender T will allow a heavier coat application. Contact Sika Canada for additional information)
Actual coverage rates and material consumption will depend upon porosity and profile of substrates. Allowance must be also made for variation in film thickness or number of coats required to achieve opacity with light (i.e. white) or bright colours (i.e. reds and yellows) on dark substrates.
Test sections are recommended to establish correct coverage
MIXING
Do not hand mix Sikafloor® materials. Mechanically mix only. Mix only that quantity which can be used within its pot life.
Pre-mix each component separately. Empty component B in the correct mix ratio to component A. Mix the combined components for at least three (3) minutes, using a low-speed drill (300 - 450 rpm) to minimize entrapping air. Use an Exomixer® type mixing paddle (recommended model) suited to the volume of the mixing container. 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. When completely mixed, Sikafloor®-261 Fast Set should be uniform in colour and consistency.
APPLICATION
Floor
Prime Coat: Apply the Sikafloor®-261 Fast Set as a prime coat onto the substrate using a brush, roller or squeegee, at a uniform coverage without puddling.
Wear Coat: Once the prime coat is tack-free, apply the wear coat using a squeegee or roller and backroll to achieve even coverage. If time between coats exceeds 24 hours at 22 °C (71 °F), abrade surface and wipe clean with a solvent dampened cloth.
Wall/Ceiling
Prime Coat: Apply the prime coat onto the substrate using a brush, or roller, at a uniform coverage.
Finish Coat: Once the prime coat is tack-free, apply the finish coats using a roller. If time between coats exceeds 24 hours at 22 °C (71 °F), abrade surface and wipe clean with a solvent-dampened cloth.
CLEAN UP
Clean all tools and equipment with Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically
