These figures are theoretical and do not allow for any additional material due to
application technique, 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
+10°C min. / +30°C max.
Ambient Temperature
+10°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.
Note: Low temperatures and high humidity conditions increase the probability of
blooming.

Sikafloor® -359 N
Mixing
Part A : part B = 78: 22 (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.
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® -359 N must be thoroughly mixed using a low speed electric stirrer
(300 - 400 rpm) or other suitable equipment.
Application Method /
Tools
Prior to application, confirm substrate moisture content, r.h. and dew point.
Seal coat:
Sealer coats can be applied by 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 and/or cured material can only be removed mechanically.

+10°C 36 hours *
+20°C 24 hours *
+30°C 16 hours *
* No max. waiting time if fully broadcast surface is free from all contaminations.
Times are approximate and will be affected by changing ambient conditions
particularly temperature and relative humidity.
Notes on Application /
Limitations
Freshly applied Sikafloor® -359 N must be protected from damp, condensation and
water for at least 24 hours.
Sikafloor® -359 N applied at different thicknesses can lead to different degrees of
matt finish.
If heating is required do not use gas, oil, paraffin or other fossil fuel heaters, these
produce large quantities of both CO2 and H2O water vapour, which may adversely
affect the finish. For heating use only electric powered warm air blower systems.

The incorrect assessment and treatment of cracks may lead to a reduced service
life and reflective cracking.
For exact colour matching, ensure the Sikafloor®-359 N in each area is applied from
the same control batch numbers.

Cleaning /
Maintenance
Methods
To maintain the appearance of the floor after application, Sikafloor® -359 N 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.
