Epoxy, waterborne

12 months from date of production

The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C.

All Density values at +23 °C.

~55 %

~43 %

Resistant to many chemicals. Contact Sika technical service for specific information.

Short-term moist/wet heat* up to +80 °C where exposure is only occasional (steam cleaning etc.).

*No simultaneous chemical and mechanical exposure and only in combination with Sikafloor® systems as a broadcast system with approximately 3 - 4 mm thickness.

Part A : Part B = 72 : 28 (by weight)

+10 °C min. / +35 °C max.

80 % r.h. max.

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 probability of blooming.

+10 °C min. / +35 °C max.

< 6 % pbw moisture content.

Test method: Sika®-Tramex meter, CM-measurement or Oven-dry-method.

No rising moisture according to ASTM (Polyethylene-sheet).

Before overcoating Sikafloor®-2540 W allow:

Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

~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..

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®-2540 W must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.

Prior to application, confirm substrate moisture content, relative air humidity and dew point.
If > 6 % pbw moisture content, Sikafloor® EpoCem® may be applied as a temporary moisture barrier (T.M.B.) 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®-2540 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.
Uneven application of the material and resulting differences in the coating layer thicknesses may cause differences in “gloss” of the surface.

Clean all tools and application equipment with water immediately after use. Hardened and/or cured material can only be removed mechanically.
