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 Concrete substrates 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.
Substrates heavily impregnated with oil must be cleaned
by torching or other methods. To check that all traces of oil have been
completely removed, sprinkle a few drops of water over the surface. If all the
water is quickly absorbed, the surface is sufficiently oil and grease free. If
water forms into globules that remain on the surface, further thorough
treatment of the substrate is necessary.
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.
-
Substrate Temperature +10oC min. / +30oC max.
-
Ambient Temperature +10oC min. / +30oC 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 3oC 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.
Application Instructions
-
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.
-
When parts A and B have been mixed, add the quartz sand
and if required the Sikadur-513 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-160 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.
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.
-
Primer:
Make sure that a continuous, pore free coat covers the
substrate. If necessary,
apply two priming coats. Apply Sikafloor-160 by brush,
roller or squeegee.
-
Levelling mortar:
Rough surfaces need to be levelled first. Apply the
levelling mortar by
squeegee/trowel to the required thickness.
-
Bonding bridge:
Apply Sikafloor-160 by brush, roller or squeegee.
-
Mortar screed / repair mortar:
Apply the mortar screed evenly on the still tacky bonding bridge, using levelling
battens and screed rails as necessary. After a short
waiting time compact and
smoothen the mortar with a trowel or Teflon coated power
float (usually 20 - 90 rpm).
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.

Notes on Application / Limitations
-
Do not apply Sikafloor-160 on substrates with rising
moisture.
-
Freshly applied Sikafloor-160 should be protected from
damp, condensation and water for at least 24 hours.
-
Avoid puddles on the surface with the primer.
-
Sikafloor-160 mortar screed is not suitable for frequent
or permanent contact with water unless sealed.
-
Practical trials should be carried out for mortar mixes
to assess suitable aggregate grain size distribution.
-
For external applications, apply on a falling
temperature. If applied during rising temperatures “pin holing” may occur from
rising air.
Construction joints require pre-treatment. Treat as
follows:
-
Static Cracks: prefill and level with Sikadur or Sikafloor epoxy
resin
-
Dynamic cracks: to be assessed and if necessary apply a
stripe coat of elastomeric material or design as a movement joint
-
The incorrect assessment and treatment of cracks may lead
to a reduced service life and reflective cracking.
-
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.
