Field of Application

White pigmented, special priming paint (wash primer) for covering priming coats on interior surfaces before applying finishing coats of synthetic emulsion paint or silicate emulsion paint. Suitable as an adhesion promoting priming coat on smooth, sound/stable substrates, e.g. gypsum plasterboards, concrete, as well as slightly absorbent gypsum plasters in mortar groups PIc - PIII, PIV and gypsum building boards. 
Particularly suitable for plasterboards: The risk of spalling is noticeably minimised, when the primer is used on thin-layered gypsum filler coatings. 
Suitable as grip promoting priming coat on smooth, slightly absorbent substrates before the application of all types of wallpapers.

Material Properties

  • Emission-minimised, solvent-free, unplasticized.
  • Easy to apply, water-dilutable, ecologically compatible, low odour.
  • Diffusion-capable, sd value 0.03 m (tinting may cause variation).
  • High adhesion to the substrate.
  • Good hiding power (opacity).
  • Grip promoting priming coat for silicate emulsion paints on substrates not allowing a proper silification.

Material Base / Vehicle

Modified synthetic dispersion/emulsion according to German standard DIN 55945.

Packaging/Package Size

Suitable Substrates

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.

Substrate Preparation

See Technical Information No. 650 for suitability of the primer on different substrates and their special pre-treatment.

Surface Coating System

Haftgrund is usually applied undiluted, but can be adjusted to working consistency to a max. of 5 % with tap (potable) water or CapaSol, if necessary.

Consumption

Approx. 150 - 200 ml/m2 on smooth surfaces. On roughly textured substrates correspondingly more. Determine the exact amount of material required by coating a test area on site.

Application Conditions

Lower Temperature Limit for Application and Drying:
+8 °C for product, substrate and ambient air.

Drying/Drying Time

At +20 °C and 65 % relative humidity recoatable after approx. 12 hours. Lower temperatures and higher humidity extend the drying time.

Tools

Haftgrund is applicable by paint roller (14 - 16 mm piles), brush and spraying equipment.  

Airless application:
Spray angle: 50°
Nozzle size: 0.021" – 0.025"
Spray pressure: 150 - 180 bar
Equip the spray gun with a filter (green, rough type), suitable for emulsion paints.
Stir well and sieve the priming paint before use.

Tool Cleaning

Clean tools/equipment immediately after use with water.

Note

Compatibility with other Materials:
To retain the specific properties, the product must not be mixed with any other materials except CapaSol, CaparolColor or AmphiColor® (AVA) and ColorExpress colourants.

German Certificates

The Fraunhofer Wilhelm-Klauditz-Institute (WKI) has audited the inoffensive application for interior use. The material is certified with German TÜV quality mark "pollutant-tested /supervised manufacturing process”. German test certificate is available on request.
