Field of ApplicationUndercoating varnish for filling intermediate coats with a good flow on dimensionally stable wooden parts, primed metals, filler-treated and sanded surfaces. Also suitable for adherent, stable existing coatings of paint and enamel before applying Capacryl PU-Gloss/Satin.
- Low odour.
- Easy and elegant application.
- High opacity (hiding/covering power).
- Easy to sand, like an alkyd resin priming varnish.
- Good filling properties.
- Promotes the adhesion of subsequent finishing.
- Suitable for children toys according to DIN EN 71-3.
- Recoatable with water-dilutable (waterborne) acrylic and alkyd resin enamels and with solvent-based alkyd resin enamels.

700 ml, 2,4 litres and 9,6 litres
Capacryl PU-Vorlack ist tintable via the ColorExpress (Capamix) tinting & mixing machine system.
When applying colours with low opacity, like Red, Orange or Yellow, it is advisable to apply one priming coat using the matching colour shade of our Priming System. Suitable Priming System colours are available via the ColorExpress tinting technique.
Keep in a cool, but frost-free place.
Shelf life of tightly closed, original packaging: 24 months.

|(–) inapplicable / (○) of limited suitability / (+) unsuitable|
Suitable SubstratesPrimed, dimensionally stable wood component parts, metals, and rigid/unplasticized PVC. Substrates must be clean, sound/stable, dry, and free from all substances that may prevent good adhesion. Maximum permissible wood moisture content (WMC) of dimensionally stable wood: 13 %.
Roughening and cleaning the primered surface.
Method of Application
Capacryl PU-Vorlack can be applied with brush, roller or spraying equipment. Stir well before use and dilute with max. 5 % to 15 % of tap (potable) water, if necessary.
Use Orelmix brushes for brush application. For manual application on large areas use a short pile (textured) polyamide (nylon) roller and directly treat the surface with a fine-porous foam roller or Orelmix brush.
Tool size should match the size of surfaces to be treated, thus allowing efficient surface painting and uniform finishing (also see supplementary application information for PU enamel system).

|1) Always apply Capacryl Holz-IsoGrund on wood with water-soluble, discolouring wood ingredients (2 x on knots).|
2) Intermediate coat, tinted to match the finishing coat in shade. For reddish, yellowish or orange shades with low opacity a suitable colour is mixed via ColorExpress. This colour slightly deviates from the selected colour providing for a better hiding power of the finishing coat.
3) Colour shades with low opacity (e.g. yellow/red/orange) may require an additional coat.
Note: Adhesion must be tested in advance for powder coatings, coil coatings and other critical/problematic substrates by trial application.
ConsumptionApprox. 100 – 130 ml/m2 per coat.
Consumption is a reference value and may vary, depending on the substrate and its condition.
Determine the exact amount of material required by coating a test area on site.
