Sikafloor® -264
2-part epoxy thin layer self-smoothing coating, textured coating,
roller and seal coat
Product
Description
Sikafloor® -264 is a two part coloured binder based on epoxy resin. Due to it’s
low viscosity, self-smoothing coatings as well as textured coatings, and seal coats
mortar screeds and broadcast screeds can be produced.
Uses
Roller, textured coat and thin self-smoothing coating for concrete and cement
screeds with normal up to medium heavy wear e.g. storage and assembly
halls, maintenance workshops, garages and loading ramps etc.
Seal coat for broadcast systems, such as multi-storey and underground car
parks, maintenance hangars and for wet process areas, e.g. in beverage
industry and food industry

Other colours on request
In case of bright colour shades, e.g. yellow or orange, colour deviations may occur
due to backfilling with quartz sand. Under direct sun radiation there may be some
discolouration and colour deviation; this has no influence to the function and
performance of the coating.

Consumption / Dosage
These figures are theoretical and do not allow for any additional material 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. 4

Sikafloor® -264
Substrate Preparation
Concrete substrates must be prepared mechanically using abrasive blast cleaning
or scarifying equipment to remove cement laitance and achieve a profiled open
textured surface.
Weak concrete must be removed and surface defects such as blowholes and voids
must be fully exposed.
Repairs to 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 up 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
+10°C min. / +30°C max.
AmbientTemperature
+10°C min. / +30°C max.
Substrate Humidity
< 4% pbw moisture content.
Test method: Sika® -Tramex meter or CM - measurement.
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 = 79 : 21 (by weight)
Mixing Time
Prior to mixing stir part A mechanically. When all of part B has been added to part
A, continuously mix for 2 minutes until a uniform mix has been achieved.
When parts A and B have been mixed, the quartz sand 0.1 - 0.3 mm and/or
Extender T must be mixed with part A and B 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 minimize air entrainment.
Mixing Tools
Sikafloor® -264 must be mechanically mixed using an electric power stirrer
(300 - 400 rpm) or other suitable equipment.
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 e.g. Sikafloor® -161 levelling
mortar (see PDS).
Coating:
Sikafloor® -264 as coating, can be applied by short-piled roller (crosswise).
Coating layer, textured:
Sikafloor® -264 is applied with a medium piled roller and then back-rolled (crosswise)
with a textured roller.
Self leveling coating layer:
Sikafloor® -264 is poured, spread evenly by means of a medium piled roller. 5
5/6
Sikafloor® -264
Roll immediately in two directions with a spiked roller to ensure even thickness and
to remove entrapped air.
Thin self leveling layer:
Sikafloor® -264 is applied with a fine serrated trowel, (max. 1 mm teeth), Roll
immediately in two directions with a spiked roller to ensure even thickness and to
remove entrapped air.
Seal coat:
Sealer coats can be applied by roller or squeegee and then back-rolled (crosswise)
with a short-piled roller.
Cleaning of Tools
Clean all tools and application equipment with Thinner C immediately after use.
Hardened / cured material can only be mechanically removed.

+30°C 6 hours 1 day
Waiting Time /
Overcoatability
Times are approximate and will be affected by changing ambient conditions
particularly temperature and relative humidity.
Notes on Application /
Limitations
Do not apply Sikafloor® -264 on substrates in which significant vapour pressure may
occur.
Do not blind the primer.
Freshly applied Sikafloor® -264 must be protected from damp, condensation and
water for at least 24 hours.
Avoid puddles on the surface with the primer.
For roller / textured coatings: Uneven substrates as well as inclusions of dirt cannot
and should not be covered by thin sealer coats. Therefore both substrate and
adjacent areas must always be prepared and cleaned thoroughly prior to
application.

Serrated trowel for smooth wearing layer:
e.g. Large-Surface Scrapper No. 565, Toothed blades No. 25
Serrated trowel for textured wearing layer:
e.g. Trowel No. 999 or Adhesive Spreader No.777, Toothed blades No. 23
The incorrect assessment and treatment of cracks may lead to a reduced service
life and reflective cracking.
For exact color matching, ensure the Sikafloor® -264 in each area is applied from the
same control batch numbers.
