Suitable Substrates

Stable existing coatings, wood and derived timber products, zinc/galvanised surfaces, copper, iron and steel, unplaticized (rigid) PVC. Unsuitable for use on stainless steel. Do not apply in the area of housetops/roofing.  The substrate must be clean, sound/stable, dry, and free from all materials that may prevent good adhesion. Max. permissible moisture content in dimensionally stable wood: 13 %; in limited dimensionally stable or unstable wood: 15 %.
Sealing of seeping wood components cannot be guaranteed in each case. Discolouration of coats may occur, if highly soluble wood components/extractives are present. Hence it is always advisable to check for sufficient sealing power by coating a test area on site.

Substrate Preparation

Wooden Parts:
Sand the surface in fibre direction, clean thoroughly, remove exuding wood extractives, e.g. wood resin/rosin and resin galls, cut sharp edges (see BFS Data Sheet No. 18).

Zinc/Galvanised Surfaces, Unplasticized (Rigid) PVC:
Wash with light ammonia solution using sanding pad according to BFS Data Sheets No. 5 and No. 22.

Copper:
Clean with nitro-thinner or phosphoric-acid solution using sanding pad to BFS Data Sheet No. 6.


Iron, Steel:
Derust to industry standard SA 2 ½ according to DIN EN ISO 12944 part 4.


Existing Paint Coatings:
Sand the surface of existing coatings slightly and clean thoroughly. Remove unstable existing coatings.

Method of Application

Apply undiluted Capalac Aqua Multiprimer with Orelmix brush, short pile/nap enamel roller or airless spraying equipment.

  • A trial application and check for adhesion by cross-cut test according to DIN EN 2409 must be completed for critical surfaces, e.g. powder coatings and coil coatings.
  • An additional finishing coat may be necessary on colours with low opacity (hiding/covering power), e.g. red, yellow and orange colour shades.
  • Apply two coats of Capalac Aqua Multiprimer on wooden parts with a high content of discolouring substances and also on knots. Allow to dry for at least 12 hours per coat; only then the discolouring wood extractives can be embedded into the priming coat.

Consumption

Approx. 100 – 130 ml/m2 per coat. Consumption is a reference value and may vary depending on substrate requirements. The exact rate of consumption is best established by a trial coating.
