Capacryl Haftprimer NAST

Suitable Substrates

Wood, derived timber products, zinc/galvanised substrates, aluminium, copper, unplasticized (rigid) PVC, stable existing coatings. Also suitable on coated metal rails of acoustic ceilings (grid ceilings). Do not apply on anodised aluminium.
The substrate must be clean, sound/stable, dry, and free from all substances that may prevent good adhesion.
Maximum permissible moisture content (WMC) in dimensionally stable wood: 13 %, in limited dimensionally stable wood and wooden parts of unstable shape: 15 %.

Substrate Preparation

Wooden Parts:
Sand the surface in fibre direction, clean thoroughly, remove all seeping wood contents, e.g. resins and resin galls and cut sharp edges (see BFS Data Sheet No. 18).

Zinc, Unplasticized/Rigid PVC:
Wash with light ammonia solution using a sanding pad as per BFS Data Sheets Nos. 5 and 22.

Aluminium, Copper:
Clean with destined detergents, e.g. Gescha Multi-Star, then sand with a plastic abrasive fleece (see BFS Data Sheet No. 6).

Existing Paint Coatings:
Sand the surface and/or treat with alkaline solution. Remove unstable existing coatings.

Coated metal rails of grid ceilings:
Clean with destined detergents, e.g. Gescha Multi-Star.

Method of Application

Capacryl Haftprimer NAST has been developed for use with the below mentioned special equipment to ensure a nearly mist-free spray application. The product cannot be applied via paint brush or roller.

Please note:
Capacryl Haftprimer NAST is adjusted for use with the mentioned spray equipment and special nozzle Caparol NAST-Frontend. Only this combination of material and equipment enable a nearly mist-free spray application.

Spray Technique:
Adjustment for coating surfaces: "Flachstrahl" (flat jet). Spray slowly lengthwise with an overlap of min. 50 % and in a spray distance of 15 cm, applying wet-on-wet.
Do not apply cross-coats!
Allow to dry and apply a second coat in the same manner, if necessary.

1)	Always apply Capacryl Holz-IsoGrund on wood containing water-soluble, discolouring substances (2x on knots).
2)	Prepare and prime defects according to substrate requirements.
3)	Colour shades of low opacity (e.g. yellow/red/orange pigmented) may require an additional coat.
Note: Adhesion must always be tested in advance for powder coatings, coil coatings and other critical substrates by trials (coating a test area on site).

Consumption

Approx. 130 - 160 ml/m² per coat.
Consumption is 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 Conditions

Low Temperature Limit for Application and Drying:
Min. 8 °C for product, substrate and ambient air.
Relative humidity must not exceed 70 %.

Drying/Drying Time

At 20 °C and 65 % relative humidity.	dust dry	dry to touch	recoatable/ sprayable with acrylic enamel	recoatable/ sprayable with alkyd enamel
after hours	1 - 2	10 - 12	12 -16	48

Lower temperatures and higher humidity extend the drying time.
