Sikafloor®-2530 W
2-PART WATER BASED EPOXY COATING
DESCRIPTION CHARACTERISTICS / ADVANTAGES
Sikafloor®-2530 W is a two part, water dispersed, col- ▪ Good chemical and mechanical resistance
oured, epoxy resin based coating for flooring applica- ▪ Water vapour permeable
tions. ▪ Water dilutable
▪ Odourless
USES ▪ Easy application
Sikafloor®-2530 W may only be used by experienced
professionals.
Sikafloor®-2530 W is used as:
▪ Coloured epoxy coating for concrete, cement
screeds, broadcast systems and epoxy mortars
▪ Can be subjected to normal up to medium heavy
mechanical and chemical loading
▪ For production areas, warehouses, car park decks,
garages, etc.
PRODUCT INFORMATION
Composition Epoxy, waterborne
Packaging Part A 4.2 kg and 12.6 kg containers
Part B 1.8 kg and 5.4 kg containers
Part A+B 6.0 kg and 18 kg ready to mix units
Appearance / Colour Resin - part A: coloured, liquid
Hardener - part B transparent, liquid
Available in various colour shades.
With light colour shades (e.g. yellow or orange) it may be necessary to ap-
ply several coats of Sikafloor®-2530 W to achieve full opacity (hiding
power).
Under direct sun radiation there may be some discolouration and colour
deviation, this has no influence on the function and performance of the
coating.
Shelf Life 12 months from date of production
Storage Conditions The product must be stored in original, unopened and undamaged sealed
packaging in dry conditions at temperatures between +5 °C and +30 °C.

APPLICATION INFORMATION
Mixing Ratio Part A : part B = 70: 30 (by weight)
Consumption ~0.2–0.3 kg/m² applied as a roller coating
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
WS-11.
Ambient Air Temperature +10 °C min. / +30 °C max.
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 probab-
ility of blooming.
Substrate 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).
Pot Life Temperature Time
+10 °C ~150 minutes
+20 °C ~120 minutes
+30 °C ~60 minutes
Curing Time Before overcoating 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
Times are approximate and will be affected by changing ambient condi-
tions particularly temperature and relative humidity.
APPLICATION INSTRUCTIONS ▪ The concrete substrate must be sound and of suffi-
cient compressive strength (minimum 25 N/mm²)
SUBSTRATE QUALITY / PRE-TREATMENT with a minimum pull off strength of 1.5 N/mm².
