Minimum 0 °C (32 °F) / Maximum 50 °C (122 °F)

A:B = 3:1 (by volume)

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

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

Note: Mixing carried out under conditions where the Sikafloor®-156 CA temperature and ambient temperature are below 18 °C (65 °F) will result in reduced product workability and slower curing rates.

Maxiumum 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®-156 CA 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 % (pbw – part by weight) as measured with a Tramex® CME/CMExpert type concrete moisture meter.

IMPORTANT: If the Waiting/ Recoat time has passed the previous coat must be lightly sanded, to remove all gloss; vacuum cleaning using a brush attachment followed promptly with a solvent wipe of the surface as per the following industry approved guideline:

• 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.

4 m²/L (160 ft²/US gal) (at 10 mil w.f.t.)

(Optional: can be thicken with Sikafloor® Extender T)

Concrete surfaces must be clean and sound. The compressive strength of the concrete substrate should be at least 25 MPa (3625 psi) at 28 days and a minimum of 1.5 MPa (217 psi) in tensile strength, at the time of the application.

Substrates must be free of contaminants such as dust, dirt, existing paint films, efflorescence, exudates, laitance, form, hydraulic or fuel oils, brake fluid, grease, fungi, mildew, biological residues or any other contaminants which may prohibit good bond or conditions of the substrate that may reduce the overall performances of Sikafloor®-156 CA.

Mix Ratio: Components A:B = 3:1 (by volume) 

IMPORTANT: 

• Do not hand mix Sikafloor®-156 CA; mechanically mix only.  
• Sikafloor®-156 CA 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®-156 CA should be uniform in appearance and consistency.

Note: Prepare only the amount that can be applied within the open time (i.e., during the pot life) and at the actual job site temperature.

Apply the primer to the prepared surface using a squeegee and back roll to provide uniform coverage. Avoid ponding.

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