Consult Sika Canada

Condition products 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 - 4).  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.

Users should refer to the most recent individual resin component product data sheet for specific "Pot Life" information by product.

Users should refer to the most recent individual resin component product data sheet for specific "Cure Time" and "Waiting Time to Overcoating"    information by product.

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 72 hours.

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

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.

The concrete surface must be clean and sound. Remove any dust, laitance, grease, oil, dirt, curing agents, impregnations, wax, foreign matters, coatings and deleterious material from the surface by any appropriate mechanical means, in order to achieve a profile equivalent to ICRI-CSP 3-4. The compressive strength of the concrete 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 Sikafloor®-156CA primer coat.

Primer /Screed Mortar Resin /Grout Coat /Topcoat

Do not hand mix Sikafloor® materials. Mechanically mix only.
Pre-stir Components A and B separately, making sure all solids, are evenly distributed and uniform consistencies are achieved within each individual Component.
Into a clean and suitably sized mixing vessel, measure and empty Component B in the correct mix ratio to Component A (see individual Product Data Sheets for specific product mix ratio information). 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® type mixing paddle (recommended model) suited to the size of the mixing container. During the mixing operations, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing. The combined Sikafloor® liquids should be uniform in colour and consistency. Mix only that quantity which can be used within its pot life at actual job site temperature.

  
Screed Mortar
Transfer the mixed Sikafloor®-156CA binder (Components A+B) into a suitable Kol type mixer; incorporating a motor spun mixing pail and a shear angle mixing blade. Gradually add Sikafloor® Trowel Quartz Aggregate to the binder to avoid excessive air entrapment. Once all ingredients are combined, mix continuously and thoroughly for three (3) minutes to ensure complete mixing. During the mixing operations, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete blending of all components. Mix only that quantity which can be used within its pot life at actual job site temperature.

Prime Coat: Apply the Sikafloor®-156CA primer using a squeegee and backroll to achieve uniform coverage. Important: Mortar must be placed onto wet primer, if the primer becomes tack-free, re-prime the substrate.

    
Screed Mortar: Maintain all control joints and expansion joints through the screed where movement is expected. Place Sikafloor® Trowel Quartz Mortar onto the wet Sikafloor®-156CA primer and uniformly spread to desired thickness. Allow loose mortar to stand for a few minutes to permit entrapped air to escape. Using a non-marking stainless steel finishing trowel, uniformly compact and smooth the surface. Screed around drains, at elevation changes or terminations must be folded into squared and keyed recesses to maintain a minimum 3 - 6 mm (1/8 - 1/4 in) thickness. Note: Do not feather edge.
   

Grout Coat: Allow mortar to cure sufficiently, to support foot traffic without damaging the surface; then apply one or two grout coats, using Sikafloor®-2002 or Sikafloor®-217 to fill and seal the pores, without ponding. Allow grout coat to cure properly, sanding lightly to remove imperfections between coats when necessary. Remove all sanding debris using an industrial vacuum. Second grout coat may not be necessary if aggregate mix is more resinous and/or has been well compacted by trowel. The grout coat should fill and seal the screed mortar and leave a thin film on the surface.
   

Topcoat: After grout coat has hardened sufficiently, sand lightly to remove imperfections. Remove all sanding debris using an industrial vacuum. Apply Sikafloor®-2002 or Sikafloor®-217 topcoat using a non-marking squeegee or flexible steel trowel, followed by backrolling to provide a uniform texture and gloss finish. Refer to specific product data sheet for further details.

Optional Topcoats: can be applied to change the surface sheen and improve long term UV resistance to colour change; Sikafloor®-317 UV will produce a matte appearance, Sikafloor®-315 plus optional Part C Wear Aggregate will produce a semi-gloss fine aggregate-textured finish. 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 Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically.
