Application

Application Information

Ambient Air Temperature

+10 °C min. / +30 °C max.

Relative Air Humidity

80 % r.h. max.
35 % min. (below +20 °C: 45 % min.)

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

< 4 % pbw moisture content.
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene sheet).

Pot Life

The material in opened containers should be applied immediately. With open containers surface film formation will happen within 1-2 hours. High temperatures and high air humidity will accelerate curing significantly.

Application steps

MIXING

Prior to use stir Sikafloor®-400 N Elastic mechanically for 3 minutes. If required the Thinner C or Extender T should be added into the Sikafloor®-400 N Elastic until a uniform mix has been achieved. Over mixing must be avoided to minimise air entrainment.

Mixing Tools:

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

APPLICATION

Prior to application, confirm substrate moisture content, relative humidity and dew point.
As a primer Sikafloor®-400 N Elastic can be applied by brush, roller or squeegee and as a coating Sikafloor®-400 N Elastic is poured and spread evenly with a trowel.

CLEANING OF TOOLS

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