Sikafloor®-261 CA Thixo

THIXO COATING (ORANGE PEEL TEXTURE) (20−24 MIL)

Sikafloor®-261 CA Thixo is a two-component, solid colour, high solids, silicone-free, heavy thixotropic viscosity, glossy epoxy resin available in an unlimited colour range. Typically installed as a seamless, high build, orange peel-textured 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 CA Thixo is also used as a top coat for high performance Sikafloor® Morritex Systems.

Mixing Ratio

Product Temperature

Condition product at temperatures between 18 °C to 30 °C (65 °F to 86 °F) before using.

Ambient Air Temperature

Minimum 10 °C  (50 °F)  Maximum: 30 °C (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

Consumption

Prime coat

Sikafloor®-261 CA (regular)
5 m2/L (200 ft2/US gal.) at 8 mil w.f.t.

Thixo wear coat

Sikafloor®-261 CA Thixo (special component B) 2.5 m2/L to 3.3 m2/L (100 ft2/US gal. to 135 ft2/US gal.) at 12 to 16 mil w.f.t.

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.
Application steps

MIXING

Mixing Ratio (A:B) = 2:1 by volume

Do not hand mix Sikafloor® materials. Mechanically mix only. 

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®-261CA prime coat (regular) and thixo wear coat (special Part B) should be uniform in colour and consistency.  

Mix only that quantity which can be used within its pot life. 

APPLICATION

Prime Coat: Apply standard viscosity Sikafloor®-261 CA as a primer onto the substrate using a brush, roller or squeegee, at a uniform coverage without puddling.


Thixo Wear Coat: Once prime coat is tack-free, apply the thixo wear coat using a squeegee or roller and backroll to achieve even coverage. Finish with a textured roller to achieve the desired surface texture. The texture peak through height will vary depending on the mil thickness and type of roller used.

CLEAN UP

Clean all tools and equipment with Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically.
