Field of Application

AmphiSilan-Putzfestiger is used for solidifying priming coats on critical substrates, e.g. chalking or highly absorbent render/plaster or existing paint coatings, sandpapered gypsum surfaces, gypsum plasterboards or substrates from which distemper paints has been washed off.
Ideally suited for solidifying priming coats on polystyrene-insulated ETICS/EWI systems or on polystyrene containing insulating plasters/renders.

Material Properties

  • Alkali-resistant.
  • Tension-free.
  • Good penetration to the substrate.
  • Non-yellowing.
  • Allows diffusion and sorption.

Substrate Preparation

The substrates must be sound/stable, dry, clean, and free from all substances that may prevent good adhesion. In Germany: Follow VOB, part C, DIN 18 363, section 3.

Apply one or two coats of AmphiSilan-Putzfestiger (depending on substrate requirements), wet-on-wet by brush or with suitable spraying equipment. Prime poorly or unevenly absorbent substrates, which need to be solidified, with AmphiSilan-Putzfestiger, thinned to a max. of 10 % with Caparol AF-Verdünner. The primer must not form a continuous, glossy film on the surface.
Allow primed substrates to dry thoroughly for at least 12 hours at 20 °C. If temperatures are low, this period extends correspondingly and might be several days.

Thinning

Thin exclusively with Caparol AF-Verdünner, if required.

Consumption

Approx. 150 – 300 ml/m2, depending on the condition and absorbency of the substrate.
Determine the exact amount of material required by coating a test area on site.

Application Conditions

Lower Temperature Limit for Application and Drying:
Can be applied in frost as well, if the substrate is dry and ice free.

Drying/Drying Time

At +20 °C and 65 % relative humidity recoatable after a minimum waiting time of 12 hours.
Lower temperatures extend the drying time up to several days.

Tools

The primer should preferably be brushed intensively into the substrate with solvent resistant tools. Application by suitable spraying equipment is also possible. Pneumatic air guns must not be used to avoid the forming of explosive mixtures.

Airless Application

Spray angle: 60°
Nozzle: 0.029"
Spray gun pressure: 50 - 60 bar
Clean tools immediately after use with white spirit.
