These figures are theoretical and do not allow for any additional material due to
surface porosity, surface profile, variations in level or 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 must 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 Moisture
Content
< 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 = 85 : 15 (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 3 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® -390 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, relative humidity and dew
point.
If > 4% pbw moisture content, Sikafloor® EpoCem® may be applied as a T.M.B.
(temporary moisture barrier) system.
Self-smoothing system (horizontal areas):
Sikafloor® -390 is poured, spread evenly by means of a serrated trowel.
Roll immediately in two directions with a spiked roller to ensure even thickness. 4
4/5
Sikafloor® -390
Self-smoothing system (vertical areas):
The first layer of Sikafloor® -390, mixed with 2.5 - 4 wt.-% Extender T, has to be
applied by trowel. After curing, apply the second layer of Sikafloor® -390, mixed with
2.5 - 4% Extender T, by trowel.
Broadcast system with slip resistance:
Sikafloor® -390 is poured, spread evenly by means of a serrated trowel then blind
the fresh layer with silicon carbide or quartz sand to excess. After final drying the
surplus silicon carbide / quartz sand must be removed by brush and the surface
must be vacuumed. The seal coat (Sikafloor® -390 + 5 wt.-% Thinner C) has to be
applied evenly by short-piled roller or squeegee.
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.

Times are approximate and will be affected by changing ambient conditions
particularly temperature and relative humidity.
Notes on Application /
Limitations
Do not apply Sikafloor® -390 on substrates with rising moisture.
Do not blind the primer coat.
Freshly applied Sikafloor® -390 must be protected from damp, condensation and
water for at least 24 hours.
Avoid puddles on the surface with the primer
Tools
Recommended supplier of tools:
PPW-Polyplan-Werkzeuge GmbH, Phone: +49 40/5597260, www.polyplan.com
Serrated trowel for smooth wearing layer:
e.g. Large-Surface Scrapper No. 565, Toothed blades No. 25
Layer thickness of wearing layer: ~ 1.5 mm.
The incorrect assessment and treatment of cracks may lead to a reduced service
life and reflective cracking.
For exact colour matching, ensure the Sikafloor® -390 in each area is applied from
the same control batch numbers.
Under certain conditions, underfloor heating or high ambient temperatures
combined with high point loading, may lead to imprints in the resin.
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. 5

Maintenance
Methods
To maintain the appearance of the floor after application, Sikafloor® -390 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.
