A:B = 1:1 by volume

Condition product between 18 °C to 24 °C (65 °F to 75 °F)

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

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).

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.

Moisture content of concrete substrate must be < 4 % (pbw – part by weight) as measured with a Tramex® CME/CMExpert type concrete moisture meter on mechanically-prepared surface according to this product data sheet (preparation to ICRI / CSP 3 - 5).  If moisture content of concrete substrate exceeds 4 % (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter, use Sikafloor®-1610 or Sikafloor®-81 EpoCem®CA or Sikafloor® 22NA or 24 NA PurCem®.

When relative humidity tests for concrete substrate are conducted per ASTM F2170 for project specific requirements, values must be ≤ 85 %. If values exceed 85 % according to ASTM F2170, use Sikafloor®-1610 or Sikafloor®-81 EpoCem®CA or Sikafloor® 22NA or 24 NA PurCem®.  ASTM F2170 testing is not a substitute for measuring substrate moisture content with a Tramex® CME/CMExpert type concrete moisture meter as described above.

Do not apply while ambient and substrate temperatures are rising, as pinholes may occur. Ensure there is no vapour drive at the time of application. Refer to ASTM D4263, may be used for a visual indication of vapour drive.

Curing times will vary according to air and substrate temperatures and relative humidity. 

Freshly applied material should be protected from dampness, condensation and water for at least 24 hours.

Mechanical, chemical and physical properties will be fully achieved at full cure.

Before applying a second coat of Sikafloor®-265 allow:

Before applying Sikafloor® Epoxy or Polyurethane on Sikafloor®-265 allow:

Note: If the Waiting/ Recoat time has passed the previous coat must be lightly sanded, to remove all gloss; vacuum cleaning and solvent wiping will be necessary to remove all traces of dust. The surface should be a uniform dullness, with no gloss present after clean-up and before applying the next coat.

Primer:
Sikafloor^®156 (where required; see Priming)
~4 m²/L (~160 ft²/US gal) at 10 mil w.f.t. per coat

Membrane:
Sikafloor^®-265
~2 m²/L (~80 ft²/US gal.) at 20 mil d.f.t. per coat.
(Minimum 2 coats recommended at 40 mil total d.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 complete coverage of surfaces. Test sections are recommended to establish correct coverage.

Mix Ratio: A:B = 1:1 by volume

Do not mix Sikafloor^® materials by hand: mechanical mix only.  Do not thin this product.  Addition of thinners (e.g., solvent or water) will retard the cure, reduce the ultimate properties of this product, and void any applicable Sika warranty.

NOTE:  Due to the difference in viscosity between Component “A” Resin and Component “B” Hardener, care must be taken to ensure that both components are thoroughly mixed-together to avoid weak or partially cured spots in the coating.

Pre-stir Components A and B separately, making sure all solids, are evenly distributed and uniform consistencies are achieved within each individual Component. 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. Keep the mixing paddle in the mix to minimize entrapped 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. Upon completion of mixing, Sikafloor®-265 should be uniform in colour and consistency. Do not mix more material than can be applied within the working time limits (i.e., Pot Life) at the actual field temperature.

Primer:

Priming is not typically required when two (2) coats of Sikafloor®-265 are being applied to a total d.f.t. of 40 mil, (i.e., at 20 mil d.f.t. per coat).

Priming is necessary if a single coat application of Sikafloor®-265 is being applied at 40 mil d.f.t. Prime with either Sikafloor®-156CA, Sikafloor®-165 FS, or Sikafloor®-1610, (Refer to Product Data Sheets for full information). 

Apply primer by squeegee at a rate of 4 m²/L (160 ft²/US gal.) over dry, mechanically-prepared concrete to achieve a uniform minimum thickness of 10 mil w.f.t. Allow the primer to cure (varies with temperature and humidity) until tack-free before applying subsequent membrane coats. Ensure that the primer is pore- and pinhole-free and provides uniform and complete coverage over the entire substrate. Refer to the individual most current and respective Product Data Sheet for specific and detailed information.

Membrane:
Pour a ribbon of material on the prepared and primed surface, then spread using a serrated squeegee or notched trowel. Back rolling is typically done immediately with a 10 mm (3/8 in) short nap, solvent-resistant roller cover to help the applied material level; over-rolling and late back rolling may cause bubbling and leave roller marks. 

IMPORTANT: Apply subsequent coats of Sikafloor®-265 or other Sikafloor^® products within 48 hours under normal curing conditions at 23 °C (75 °F), 50 % R.H.  If the Waiting/ Recoat time has passed the previous coat must be lightly sanded, to remove all gloss; vacuum cleaning and solvent wiping will be necessary to remove all traces of dust. The surface should be a uniform dullness, with no gloss present after clean-up and before applying the next coat.

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