Min. ~ 0 °C (32 °F)  Max. ~ 50 °C (122 °F)

A:B = 2:1 by volume

Condition product at temperatures between 18 °C and 30 °C (65 °F and 86 °F) before using and during the application.

Minimum: 10 °C (50 °F) / Maximum: 30 °C (86 °F)

Note: Mixing carried out under conditions where the Sikafloor®-261 Fast Set temperature and ambient temperature are below 18°C (65°F) will result in reduced product workability and slower curing rates.
 

Maximum 85 % (during application and curing).

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.  Be aware that the substrate temperature may be lower than the ambient temperature.

Minimum: 10 °C (50 °F) / Maximum: 30 °C (86 °F)

Note: Any attempt to apply Sikafloor®-261 Fast Set at substrate temperature conditions less than 18 °C (65 °F) will result in an increase in viscosity and slower cure rates.

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.

IMPORTANT: If the maximum waiting time has been exceeded. The previous coat must be lightly sanded, to remove all gloss; vacuum cleaning using a brush attachment followed promptly with a solvent wipe off the surface as per the following generally accepted practices:

• Avoid using solvent that can leave a oily residue: (such as, but not limited to most mineral spirit).
• Avoid Paper Towels: Pre-treated shop towels or standard paper towels may contain silicone or manufacturing additives that will ruin your paint job. Stick to lint-free cotton cloths or dedicated microfiber towels.  
• Change Rags Frequently: As soon as a rag becomes visibly dirty, discard it or fold it to a clean side. Continuing to wipe with a saturated, dirty rag just re-deposits contaminants onto the surface.  

• Wet Wipe: Pour a solvent (onto the first rag. Do not dip the rag into the solvent container; pour it directly to keep your supply clean).  à
• Lift: Wipe down a small, manageable section (e.g., ~0.5 m² [~ 4-6 ft²]) of the surface. Use enough pressure to break up and lift the oils or sanding dust. Rotate the cloth frequently so you are always using a clean spot.
• Dry Wipe: Before the solvent can flash off (evaporate) and dry on the surface, wipe the same section with a second, clean, lint-free rag. When used correctly, this second cloth absorbs residual solvent and removes materials that could reduce or prevent adhesion or the proper performance of the next coat.

Wall and Ceiling

(Addition of Sikafloor® Extender T will allow a heavier coat application. Contact Sika Canada for additional information)

Note: Actual coverage rates and material consumption will depend upon porosity and profile of substrates. Allowance must also be 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 substrate. Test sections are recommended to establish correct coverage.

Mixing ratio A:B = 2:1 (by volume) 

IMPORTANT: 

• Do not hand mix Sikafloor®-261 Fast Set; mechanically mix only.  
• Sikafloor®-261 Fast Set must be applied as supplied. 

Pre-stir Components A and B separately, making sure all solids, are evenly distributed. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin) or empty Component A into a suitably sized and clean pail and add Component B in the correct ratio. Blend the combined components thoroughly at low speed (300 - 450 rpm) for at least three (3) minutes using a drill fitted with an Exomixer® or Jiffy type paddle suited to the dimensions of the mixing container and keep the mixing paddle in the mix to avoid entrapping air. Take care 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. Do not attempt to attend to unmixed material that may gather on the sides of the mixing container while mechanical or electrical parts are in motion. When completely mixed, Sikafloor®-261 Fast Set should be uniform in appearance and consistency.

Note: Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.

Floors

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. 

Walls/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.

IMPORTANT: Read the Waiting Time / Overcoating section on page 3 and 4 of this document for specific instructions regarding surface preparation.

Clean all tools and equipment with a non-flammable solvent. Once hardened, product can only be removed mechanically.
