System Structure
Roller coating:
Primer: 1 x Sikafloor® -144 / -156
Coating: 2 x Sikafloor® -266 CR
Note: In cases of limited exposure and normal absorbent concrete substrates
priming with Sikafloor® -144 / -156 is not necessary.
Textured coating:

1 st layer: 1 x Sikafloor® -266 CR
2 nd layer: 1 x Sikafloor® -266 CR mixed with Extender T
The 2nd layer of Sikafloor® -266 CR can be mixed with additional aggregate in order
to improve slip resistance, but particle emissions could increase.
Note: In cases of limited exposure and normal absorbent concrete substrates
priming with Sikafloor® -144 / -156 is not necessary.
Self-smoothing system:
Primer: 1 x Sikafloor® -144 / -156

Sikafloor® -266 CR
These figures are theoretical and does not allow for any additional material required
due to surface porosity, surface profile, variations in level and wastage etc.
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.
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.
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.
High spots must be removed by e.g. 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.
Application
Conditions /
Limitations
Substrate Temperature
+15°C min. / +30°C max.
Ambient Temperature
+15°C min. / +30°C max.
Substrate Humidity
< 4% pbw moisture content.
Test method: Sika® -Tramex meter, CM-measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).
Relative Air Humidity
80% r.h. max.
Dew Point
Beware of condensation!
The substrate and uncured floor must be at least 3°C above dew point to reduce
the risk of condensation or blooming on the floor finish.
Application
Instructions
Mixing
Part A : part B = 80: 20 (by weight)
Mixing Time
Prior to mixing, stir part A mechanically. When all of part B has been added to part
A, mix continuously for 2 minutes until a uniform mix has been achieved.
When parts A and B have been mixed, add the quartz sand 0.1 - 0.3 mm and mix
for a further 2 minutes until a uniform mix has been achieved.
To ensure thorough mixing pour materials into another container and mix again to
achieve a consistent mix.
Over mixing must be avoided to minimise air entrainment.
Mixing Tools
Sikafloor® -266 CR must be thoroughly mixed using a low speed electric stirrer
(300 - 400 rpm) or other suitable equipment. 4

Application Method /
Tools
Prior to application, confirm substrate moisture content, r.h. and dew point.
If > 4% pbw moisture content, Sikafloor® EpoCem® may be applied as a T.M.B.
(temporary moisture barrier) system.
Levelling:
Rough surfaces need to be levelled first. Therefore use Sikafloor® -144 / -156
levelling mortar (see PDS).
Roller coating:
Sikafloor® -266 CR as coating can be applied by short-piled roller (crosswise).
Textured coating:
Sikafloor® -266 CR is applied with a serrated trowel and then back-rolled
(crosswise) with a textured roller.
Wearing course smooth:
Sikafloor® -266 CR is poured, spread evenly by means of a serrated trowel.
After spreading the material evenly, turn the serrated trowel and smooth the surface
in order to achieve an aesthetically higher grade of finish.
Roll immediately (within max. 10 minutes of application) in two directions with a
spiked roller to ensure even thickness and to remove entrapped air. To obtain the
highest level of aesthetic finish, spike roll in two directions at a 90 degree angle,
passing only once in each direction.
Cleaning of Tools
Clean all tools and application equipment with Thinner C immediately after use.
Hardened and/or cured material can only be removed mechanically.
