PU-Alkyd Aqua

Suitable Substrates

Primed, dimensionally stable wood component parts, primed metals and unplasticized/rigid PVC.
The substrate must be clean, sound/stable, dry and free from all substances that may prevent good adhesion. Maximum permissible moisture content in dimensionally stable wood: 13 % (WMC).

Substrate Preparation

Roughening and cleaning the primered surface.

Method of Application

PU-AlkydGeo can be applied by brush, roller or spraying equipment. Stir well before use and dilute, if necessary, with max. 5 - 15 % of tap (potable) water for intermediate coat.
The indications as stated above may vary, depending on the type/brand of spray equipment used. For brush application use special brushes, suitable for aqueous enamels.
Manual application on large/seamless surfaces: Apply with a textured, short pile polyamide (nylon) roller and treat immediately with a fine-porous foam roller or special brush for aqueous enamels.

For an efficient application and an even surface treatment the tool sizes should be adjusted to the surface area to be coated.

Guidelines for Spray Application:

	Ø Nozzle	Spray Pressure	Air Pressure	Dilution
Airless	0.009 - 0.012 inch	200 bar	–	max. 5 %
Airmix/Aircoat	0.011 - 0.013 inch	120 bar	2.5 bar	max. 5 %
Low pressure	1.8 - 2.2 mm	–	approx. 0.5 bar	max. 15 %
High pressure	1.8 - 2.0 mm	–	2 - 3 bar	max. 15 %

1) Always apply Capacryl Holz-IsoGrund on wood containing water-soluble, discolouring substances (2 x on knots). 2) Apply two intermediate coats on dimensionally stable wood component parts, as per BFS Data Sheet No. 18. 3) Sand the surface after applying an additional intermediate coat. Note: Adhesion must be tested in advance for powder coatings, coil coatings and other critical substrates by trials.

Consumption

Approx. 100 - 120 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 & Drying:
Minimum 8 °C for product, ambient air and substrate.
Relative humidity must not exceed 70 %.

Drying/Drying Time

At 20 °C and 65 % relative humidity.	dust dry	recoatable	cured
after hours	1 - 2	10 - 12	48

Lower temperatures and higher humidity extend the drying time.

Tool Cleaning

Immediately after use with water.
