A:B = 2:1 (by volume)

Precondition material for at least 24 hours between 18 °C to 30 °C (65 °F to 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®-217 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®-217 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 on mechanically prepared surface according to this product data sheet (preparation to ICRI / CSP 3 - 4).

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

Protect from dampness, condensation and water contact during the initial 72 hour cure period.

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

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).   
• 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.

2 m²/L to 4 m²/L (80 ft² / US gal to 160 ft² / US gal) at 10 - 20 mils w.f.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®-217.

Mixing ratio A:B = 2:1 (by volume).   

IMPORTANT: 

• Do not hand mix Sikafloor^® materials; mechanically mix only.  
• Sikafloor®-217 must be applied as supplied. 

Clear Resin : Pre-mix each component separately. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin). 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® or Jiffy 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. 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®-217 should be uniform in colour and consistency.

Field Pigmented using Sikafloor® Epoxy Pigment Pack CA: Pre-stir each component separately, including the content of the Sikafloor® Epoxy Pigment Pack CA to ensure product uniformity. For all colours, add one (1) 946 ml Sikafloor®-217 for every 7.56 L (2 US gal.) of Component A (Resin). Mix at low speed (300 - 450 rpm) for three (3) minutes until a uniform colour is achieved using a drill fitted with an Exomixer® or Jiffy type paddle. Be careful not to introduce any air bubbles during the mixing process. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin) and mix for an additional three (3) minutes. Be careful 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®-217 should be uniform in colour 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.

Apply Sikafloor®-217 using a non-marking squeegee or flexible steel trowel, followed by backrolling to provide a uniform texture and appearance. Over-rolling and or late back rolling may cause bubbling and leave roller marks. A second top coat application or a thicker initial application maybe required to achieve a specific texture or desired final appearance.

Note: Sika Canada strongly recommends that a test area be applied to confirm specific top coat selection and application rates required to produce the desired final appearance.

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