The product is tintable via the ColorExpress (Capalac mix) machine system/stations in many special colours of colour collection Caparol 3D System plus and in many shades of other collections.
When using colour shades of low opacity (hiding/covering power), e.g. red, orange or yellow, it is advisable to apply a first (priming) coat of product, tinted in a matching priming system colour, available via ColorExpress.
StorageKeep in a cool place.
Keep the can always tightly closed.

|(–) inapplicable / (○) of limited suitability / (+) suitable|
Suitable SubstratesUncoated and coated wooden parts. The substrate must be clean, sound/stable, dry, and free from all substances that may prevent good adhesion. Wood moisture content (WMC): Maximum permissible WMC of dimensionally stable wood: 13 %; limited dimensionally stable or unstable wood: 15 %
Substrate PreparationWooden Parts:
Sand the surface in fibre direction, clean thoroughly, remove seeping substances, e.g. wood resin/rosin and pitch/resin pockets, cut sharp edges (see BFS Data Sheet No.18).
Sound/Stable Existing Coatings:
Roughen (sand) the surface and/or treat with alkali. Remove unstable existing coatings.
Method of ApplicationCapalac GrundierWeiß is adjusted ready-to-use for brush application. Stir well before use and thin with 5 - 10 % of synthetic resin thinner or use Caparol AF-Verdünner (non-aromatic thinner), if necessary.

|✱ Always apply two intermediate coats on dimensionally stable wooden parts, as per German BFS Data Sheet No. 18.|
1) Only required for wood at risk of blue stain.
ConsumptionApprox. 100 ml/m2 per coat. Consumption is only a guide value and may vary, depending on substrate requirements. Determine the exact amount of material required by coating a test area on site.
Application ConditionsLower Temperature Limit for Application and Drying:
+ 5 °C for product, substrate and ambient air.
Relative humidity must not exceed 80 %.
|At 20 °C and 65 % relative humidity||dust dry||dry to touch||recoatable|
|after hours||2 - 3||4 - 5||24✱|
Lower temperatures and higher humidity extend the drying time.
✱Respect a drying time of 2 - 3 days before applying finishing coats of Capacryl or Capadur enamels. The priming coat and the wooden substrate must be free of solvents in order to avoid blistering.
Immediately after use with white spirit.
NoteCheck the isolating property of Capalac GrundierWeiß before applying topcoats of waterborne enamels, e.g. Capacryl and Capadur Wetterschutzfarbe NQG.
