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.

~ 43% (by volume) / ~ 55% (by weight)

Resistant to many chemicals. Contact Sika Technical Services for additional 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 approx. 3 - 4 mm thickness.

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

+10 °C min. / +30 °C max.

80 % 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. / +30 °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.

Note: Times are approximate and will be affected by changing ambient conditions.

~ 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-10 and Sikafloor® Multidur WT-10.

Prior to mixing all parts, mix part A (resin) using a low speed single paddle electric stirrer (300–400 rpm) to mix liquid and all the coloured pigment until a uniform colour has been achieved. Add part B (hardener) to part A and mix part A + B continuously for 2,0 minutes until a uniformly coloured mix has been achieved. To ensure thorough mixing pour materials into a clean container and mix again for at least 1,0 minute to achieve a smooth consistent mix. Over mixing must be avoided to minimise air entrainment.During the final mixing stage, scrape down the sides and bottom of the  mixing container with a flat or straight edge trowel at least once to ensure complete mixing. Mix full units only. Mixing time for A+B = 3 minutes.

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 Pour mixed Sikafloor® primer onto the prepared substrate and apply by brush, roller or squeegee then back roller in two directions at right angles to each other. Ensure a continuous, pore free coat covers the substrate. If necessary, apply two priming coats.Confirm waiting /overcoating time has been achieved before applying subsequent products. Refer to individual primer Product Data Sheet. Seal / top coat After waiting the appropriate overcoating time, pour the mixed Sikafloor®-2540 W onto prepared substrate and apply evenly using a nylon roller at the required consumption rate in two directions at right angles to each other. A seamless finish can be achieved if a ‘wet’ edge is maintained during application.

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

To maintain the appearance of the floor after application, Sikafloor®-2540 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.
