Application

Application Information

Mixing ratio

Part A : Part B = 16 : 84 (by weight)

Ambient air temperature

+10°C min. / +30 °C max.

Relative air humidity

75% r.h. max.

 

Dew point

Beware of condensation!
The substrate must be at least 3˚C above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure of final finish. Be aware that the substrate temperature may be lower than the ambient temperature

Substrate temperature

+10°C min. / +30 °C max.

Substrate moisture content

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

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.
Application steps

SUBSTRATE PREPARATION

For steel sand blasting or wire brushing is essential. Should be free from oil, dirt and grease. For concrete remove cement skin, loose particles etc. Cavities, pin holes should be levelled

MIXING

Inertol® Poxitar® is supplied in two parts. Stir Part B thoroughly to remix any settle part, add Component A and mix thoroughly with an electric stirrer with up and down movements for 3 minutes.

APPLICATION

Priming:

Using Friazinc® R for priming has the advantage that no under rusting occurs in case of damage to the top coat.

Application Method / Tools:

Brush application: With distemper brushes, round brushes or radiator brushes.
Roller application: With short pile lamb skin roller

CLEANING OF EQUIPMENT

Wash tools with Sika® Colma Cleaner immediately after use. Hardened material can only be removed mechanically.
