+10 °C min. / +35°C max.

80% max.

Beware of condensation!

The substrate must be at least +3 °C 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.

+10 °C min. / +35 °C max.

The following test methods can be used: Sika®-Tramex meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).

Note: Times are approximate and will be affected by changing ambient conditions

Sikafloor®-264 HC N, Sika® Extender T & quartz sand must be thoroughly mixed using a low speed electric stirrer (300–400 rpm) or other suitable equipment. For the preparation of mortars use a forced action mixer of rotating pan, paddle or trough type. Free fall mixers should not be used.

• The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum pull off strength of 1.5 N/mm².
• The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. If in doubt apply a test area first.
• Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed.
• Repairs to the substrate, filling of blowholes/voids and surface levelling can be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard ® range of materials.
• The concrete or screed substrate has to be primed or levelled in order to achieve an even surface.

Concrete substrates must be prepared mechanically using abrasive blast cleaning, scarifying, and/or grinding equipment to remove cement laitance and achieve an open textured surface.

High spots must be removed by grinding. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.

Primer

1. Prior to mixing all parts, mix separately Part A (resin) using an electric single paddle mixer (300–400 rpm) or other similar equipment. Mix liquid and all the coloured pigment until a uniform colour / mix has been achieved.
2. Add Part B (hardener) to Part A and mix Part A + B continuously for 2–3 minutes until a uniformly coloured mix has been achieved.
3. To ensure thorough mixing pour materials into another clean container and mix again for ~1 minute to achieve a smooth consistent mix. Excessive mixing must be avoided to minimise air entrainment.
4. During the final mixing stage, scrape down the sides and bottom of the mixing container with a straight edge trowel or spatula at least once to ensure complete mixing. Mix full units only. Total mixing time ~3 minutes.
5. Free fall mixers should not be used.

Note: Part A (resin) and coloured pigment can bemixed a day earlier.

Texture Coating

1. Prior to mixing all parts, mix separately Part A (resin) using an electric single paddle mixer (300–400 rpm) or other similar equipment. Mix liquid and all the coloured pigment until a uniform colour / mix has been achieved. Then add Sika® Extender T and mix for ~1 minute until a uniform mix is achieved.
2. Add Part B (hardener) to Part A and mix Part A + B continuously for ~1 minute, and then add quartz sand and continue mixing for another 1–2 minutes until a uniformly coloured mix has been achieved.
3. To ensure thorough mixing pour materials into another clean container and mix again for ~1 minute to achieve a smooth consistent mix. Excessive mixing must be avoided to minimise air entrainment.
4. During the final mixing stage, scrape down the sides and bottom of the mixing container with a straight edge trowel or spatula at least  once to ensure complete mixing. Mix full units only. Total mixing time ~4 minutes.
5. Free fall mixers should not be used.

Note: Part A (resin) and coloured pigment can be mixed a day earlier.

Prior to application, confirm substrate moisture content, relative air humidity and dew point are within the limits stated in the Product Data Sheet of the respective product. If > 4 % pbw moisture content, Sikafloor® EpoCem® may be applied as a TMB (temporary moisture barrier) system. Contact Sika Technical Service for more information.

Primer
Make sure that a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. For overcoating time refer to the most recent Product Data Sheet. Apply Sikafloor®-264 HC N by brush, roller or squeegee. Preferred application is by using a squeegee and then back rolling crosswise.

Levelling
Rough surfaces must be levelled using Sikafloor®-161 HC levelling mortar (refer to the most recent Product Data Sheet). For overcoating time of Sikafloor®-161 HC, refer to the most recent Product Data Sheet.

Texture coating
Sikafloor®-264 HC N + Sika® Extender T + quartz sand coating can be laid using a pin rake, notch trowel and back roll (crosswise) with a foam type textured roller. In large areas, change the textured roller when inconsistencies (eg. flat texture) uneven areas and roller marks are observed.

For more information on application, refer to the most recent Product Data Sheet of the respective product and/or Application Method Statement of the Product/System, copies of which will be supplied on request.

Clean all tools and application equipment with Thinner C or suitable solvent immediately after use. Hardened and/or cured material can only be removed mechanically.

All spillages must be removed immediately!
To maintain the appearance of the floor after application, regularly clean the floor using methods such as dust mopping, wet mopping, scrubber drying, wet scrubbing and wet vacuuming etc. with suitable detergents and waxes. Refer to the guideline "Cleaning & Maintenance of Sikafloor Systems".
