Application

Application Information

Ambient Air Temperature

+2°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

+2°C min. / +30°C max.
Frozen substrates must defrost for 24 hours.

Substrate Moisture Content

Visible damp free (maximum 18% wood moisture equivalent).
< 6% pbw moisture content Test method: Sika®-Tramex meter, < 4% 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 approx. 24 hours. High temperatures and high air humidity will accelerate curing significantly.

Curing Time

Before overcoating Sikafloor®-405 allow:

7 days

+30°C

12 hours

7 days

Application should take place within 7 days, further delays will require re-priming with Sika® Reactivation Primer, assuming that all dirt has been removed and contamination is avoided.
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Consumption

~0.4 - 1.45 kg/m²/layer depending on the application. Please refer to the respective System Data Sheet.
Application steps

MIXING

Slightly stir Sikafloor®-405 mechanically before using.


Mixing Tools:
Sikafloor®-405 must be 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 the product can be applied by brush or medium pile nylon roller and as acoating by long pile roller.

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.
