< 25 g/L (Clear)

~85

> 2.4 MPa (> 350 psi) (substrate failure)

Clear Resin and Factory Pre-tint A:B = 2:1 by volume 

Colour Pod Pigment Add 1 x 500 ml (16.9 oz) CTM Colour Pod or Sikafloor® UTE Colour Pak for every 3.78 L (1 US gal.) of ECTR Clear Part A (Resin)

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

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.

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 (85 °F) 

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. 

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. 

Curing times will vary according to ambient air and substrate temperatures and relative humidity. 
Freshly applied material should be protected from dampness, condensation, and water for at least 48 hours. 
Mechanical, chemical, and physical properties will be fully achieved at full cure.

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.

Smooth Coating:  Prime coat: (8 mil) 5 m²/L (203 ft²/US gal.)

                                Finish coat: (15 mil) 2.6 m²/L (106 ft²/US gal) 

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

The concrete surface must be clean and sound. Remove any dust, laitance, grease, oil, dirt, curing agents, impregnations, wax, foreign matter, coatings, and detritus from the surface by appropriate mechanical means such as shot blasting, grinding or other mechanical means to achieve an open surface profile equivalent to ICRI / CSP 3 – 4 similar in texture to fine sandpaper.  The compressive strength of the concrete substrate should be at least 25 MPa (3625 psi) at 28 days and at least 1.5 MPa (218 psi) in tension at the time of application of ECTR.

Mix Ratio: A:B 2:1 by volume.   Do not hand mix ECTR materials. Mechanically mix only. 

  
Clear and Factory Pre-tint:   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. When completely mixed, ECTR should be uniform in colour and consistency. Mix only that quantity which can be used within its pot life.

  
Colour Pod Pigmented: Premix each component separately, including the CTM Colour Pod or Sikafloor® UTE Colour Pak to ensure product uniformity. For all colours, add one (1) 500 ml (16.9 oz) CTM Colour Pod or Sikafloor® UTE Colour Pak for every 3.78 L (1 US gal.) of Component A (Resin) and 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 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.  When completely mixed, ECTR should be uniform in colour and consistency. Mix only that quantity which can be used within its pot life.

  
NOTE: When using brighter colours, additional coats may be required. Using more color additive than recommended will result in extended cure times and reduced chemical and abrasion resistance.

Prime Coat: Apply mixed ECTR 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 brush, squeegee, and backroll to achieve even coverage. 

  
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.

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