Product Data
Form
Appearance / Colours
Resin - part A: coloured, liquid
Hardener - part B: white, liquid
Available in various colour shades.
With light colour shades (e.g. yellow or orange) it may be necessary to apply several
coats of Sikafloor® -2530 W to achieve full opacity (hiding power).

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.
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
< 6% 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
75% r.h. max., adequate fresh air ventilation must be provided to remove excess
moisture during curing.
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. 4

Application
Instructions
Mixing
Part A : part B = 70 : 30 (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 minimise air entrainment.
Mixing Tools
Sikafloor® -2530 W 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.
If > 6% 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. When used as a primer always apply by brush.
Seal coat:
Sikafloor® -2530 W is spread evenly by means of a short pile roller.
A seamless finish can be achieved if a “wet” edge is maintained during application.
Sikafloor® -2530 W can also be applied by airless spray (spray pressure ~ 300 bar,
nozzles with a diameter of 0.53 mm / 0.021 inch and a spray angle 60°).
Uneven application of the material and resulting differences in the coating layer
thicknesses may cause differences in “gloss” of the surface.
Cleaning of Tools
Clean all tools and application equipment with water immediately after use.
Hardened and/or cured material can only be removed mechanically.
Temperature Time
+10°C ~ 150 minutes
+20°C ~ 120 minutes
+30°C ~ 60 minutes
Potlife
Before applying Sikafloor® -2530 W on Sikafloor® -156 allow:
Substrate temperature Minimum Maximum
+10°C 24 hours 4 days
+20°C 12 hours 2 days
+30°C 6 hours 1 day
Before applying Sikafloor® -2530 W on Sikafloor® -2530 W allow:
Substrate temperature Minimum Maximum
+10°C 48 hours 7 days
+20°C 20 hours 5 days
+30°C 10 hours 3 days
Waiting Time /
Overcoating
Times are approximate and will be affected by changing ambient conditions
particularly temperature and relative humidity.
When relative air humidity is ≥ 75% the waiting time is increased by at least 24
hours. 5

Notes on Application /
Limitations
Do not apply Sikafloor® -2530 W on substrates with rising moisture.
Freshly applied Sikafloor® -2530 W should be protected from damp, condensation
and water for at least 24 hours.
Avoid puddles on surface with the primer.
Always ensure adequate fresh air ventilation when using Sikafloor® -2530 W in
confined spaces to avoid curing problems.
The “gloss” of the finish can vary with temperature and the absorbency of the
substrate.

The incorrect assessment and treatment of cracks may lead to a reduced service
life and reflective cracking.
For exact colour matching, ensure the Sikafloor® -2530 W in each area is applied
from the same control batch numbers.
For spray application the use of protective health & safety equipment is mandatory!
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.

Cleaning /
Maintenance
Methods
To maintain the appearance of the floor after application, Sikafloor® -2530 W 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.
