Ambient Air Temperature
+8 °C min. / +35 °C max.
Relative Air Humidity
80 % r.h. max
Dew Point
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.
Substrate Temperature
+8 °C min. / +35 °C max.
Substrate Moisture Content
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 CSP-3 to CSP-4 as per ICRI guidelines). Do not apply to concrete substrate with moisture levels > 4% mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter. If moisture content of concrete substrate is > 4% by mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter, use Sikafloor 81 EpoCem.

Waiting Time / Overcoating
Before applying Sikafloor®-264/264 HC on Sikafloor®-161/161 HC allow:
Substrate temperature | Minimum | Maximum |
+10 °C | 24 hours | 3 days |
+20 °C | 12 hours | 2 days |

EQUIPMENT
Sikafloor®-264 HC 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.
SUBSTRATE QUALITY
- 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.
SUBSTRATE PREPARATION
Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface.
High spots must be removed by e.g. diamond 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
MIXING
Pre - mix is recommended for component A & colour component one day prior to application. Prior to mixing, stir part A mechanically when all of part B has been added to part A & mix for 1minute, then add quartz filler & mix continuously for 2-3 minutes until a uniform mix has been achieved. De-can whole mixed materials to another container & mix for a further 1 minute to achieve consistent mix & avoid any lumps or unmixed particle in the container. Over mixing must be avoided to minimize air entrainment.
APPLICATION
Prior to application, confirm substrate moisture content, relative air humidity and dew point. If > 4 % pbw moisture content, Sikafloor® EpoCem® may be applied as a T.M.B. (temporary moisture barrier) system.
Primer
Make sure that a continuous, pore free coat covers the substrate. Sikafloor®-161/161 HC by trowel & back roll with spike roller.
Broad cast:
Broad cast quartz sand in excess uniformly on base layer
Sealcoating
Sikafloor®-264/264 HC topping can be applied by sqeezee & back roll with coating roller.
CLEANING OF TOOLS
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
CLEANING
To maintain the appearance of the floor after application, Sikafloor®-264 HC must have all spillages removed immediately and must be regularly cleaned using rotary brush, mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum techniques etc. using suitable detergents and waxes.
