APPLICATION INFORMATION
Mixing Ratio Part A : part B = 79 : 21 (by weight)
Consumption ~1.8 kg/m2/mm (1L/m2/mm) applied as a
self-smoothing wearing course. These figures are theoretical and do not allow
for any additional material due to surface porosity, surface profile,
variations in level or wastage etc.
For detailed info, please refer to the System data sheet Sikafloor
Multidur ES- 23 / 24 and Sikafloor Multidur EB-24
Ambient Air Temperature +10 oC min. / +30 oC max.
Relative Air Humidity 80 % r.h. max.
Dew Point Beware of condensation! The substrate and
uncured floor must be at least 3 oC 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.
Substrate Temperature +10 oC min. / +30 oC 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). Note: Use Sikafloor 161 Primer
for substrates to 6 pbw. For substrates with moisture content above 6% pbw use
Epocem 81

APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
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.
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
blow holes 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.
All dust, loose and friable material must be completely removed
from all surfaces before application of the product, preferably by brush or
vacuum.
MIXING
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 Extender T 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-263 SL 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. Care should be given to use a mixing head/ mixing vessel combination that
has the mixing head submerged beneath the surface of the full mix. Failure to
do this may entrain excess air into the mix that can create difficulties in
expelling all air from the applied floor with the spiked roller.
APPLICATION
Prior to application, confirm substrate
moisture content, relative air humidity 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
161 /-160 by roller then squeegee to overcome any possibilty of entrapped air
from the substrate
creating pin/air holes in the finished
product. Preferred application is by using a squeegee and then backrolling
crosswise.
Levelling:
Rough surfaces need to be levelled first.
Therefore use e.g. Sikafloor 161/-160 levelling mortar (see PDS).
Wearing course smooth:
Sikafloor-263 SL is poured, spread evenly
by means of a serrated tooth pattern trowel or pin rake.
Roll immediately in two directions with a
spiked roller to ensure even thickness and expel all latent, entrapped air from
the mixing process.
Broadcast system:
Sikafloor-263 SL is poured, spread evenly
by means of a serrated trowel. Then, level and remove any entrapped air with a spiked
roller and after about 15 minutes (at +20 oC) but before 30 minutes (at +20 oC),
broadcast with quartz sand, at first lightly and then to excess. When the floor
has set hard (approx. 10 hours @ 21 degrees C), remove all excess broadcast
sand by sweeping and thorough vacuuming. Note: Use Sikafloor Booster additive
to accelerate this process; (refer to Sika Technical Dept for direction.) Apply
finish coats of Sikafloor 264 high build flowable epoxy. Usually 2 coats
required.
Coverage rates: 2-3m2 per L first coat .
5-6 m2 per L second coat ( rates will vary depending on the size of the
broadacst aggregate selected
CLEANING OF EQUIPMENT
Clean all tools and application equipment
with Thinner C immediately after use. Hardened and/or cured material can only
be removed mechanically.
MAINTENANCE
To maintain the appearance of the floor
after application, Sikafloor-263 SL 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
FURTHER INFORMATION
Substrate quality & Preparation
Please refer to Sika Method Statement: EVALUATION
AND PREPARATION OF SURFACES FOR FLOORING SYSTEMS.
Application instructions

& APPLICATION OF FLOORING SYSTEMS.
Maintenance

REGIME.
IMPORTANT CONSIDERATIONS
Do not apply Sikafloor-263 SL on
substrates with rising moisture.
Do not blind the primer.
Contaminants such as silicone residue
present on the job site, either airbourne or from equipment, may cause defects
in the surface of the finished product due to a change in surface tension. A
test area may
be required.
Freshly applied Sikafloor-263 SL should
be protected from damp, condensation and water for at least 24 hours.
For areas with limited exposure and
normally absorbent concrete substrates priming with Sikafloor-156/-161/-160 is
not necessary for roller or textured coating systems.
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.
The incorrect assessment and treatment of
cracks may lead to a reduced service life and reflective cracking.
For exact colour matching, ensure the Sikafloor-263SL
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
