Application

Application Information

Mixing Ratio

Part A : part B = 70 : 30 (by weight)

Ambient Air Temperature

+10 °C min. / +30 °C max.

Relative Air Humidity

80 % 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.

Substrate Temperature

+10 °C min. / +30 °C max.

Substrate Moisture Content

< 6 % pbw moisture content.
Test method: Sika-Tramex meter or CM - measurement.
No rising moisture according to ASTM (Polyethylene-sheet).

Application steps

MIXING

Prior to mixing stir part A mechanically. When all of part B has been added to part A, continuously mix 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 minimize air entrainment.
Sikafloor®-2530 W LP must be mechanically mixed using an electric power stirrer (300 – 400 rpm) or other suitable equipment.

 

APPLICATION

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.
Coating
Sikafloor®-2530 W LP 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 LP 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 EQUIPMENT

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

CLEANING

To maintain the appearance of the floor after application, Sikafloor®-2530 W LP 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.
