Capalac Aqua Metallschutz

Suitable Substrates

Iron, steel, zinc (galvanised steel), aluminium, copper, stable existing paint coatings.
The substrate must be clean, sound/stable, dry and free from all substances that may prevent good adhesion. 
Do not use for the coating of roofings and anodized aluminium!
Existing coatings may require a trial coating and check for proper adhesion. This applies in particular for powder and coil coatings.

Substrate Preparation

Iron, Steel:
Derust to industry standard SA 2½ (blasting) according to DIN EN ISO 12944-4.
A thorough removal of rust to the degree of purity ST 3 by mechanical means or by hand may be sufficient, if corrosive loads are low (e.g. indoors without any formation of water condensation and other aggressive influences).

Zinc, Galvanized Steel:
Roughen and clean with non-woven web and Multistar, 1 : 5 diluted with tap (potable) water, otherwise use light ammonia solution or prepare via sweeping technique as per German BFS-Merkblatt (Data Sheet) No. 5.

Aluminium: 
Roughen/clean with non-woven web and Multistar, 1 : 5 diluted with tap (potable) water. Germany: Follow BFS Data Sheet No. 6.

Copper: 
Roughen/clean with non-woven web and Multistar, 1 : 5 diluted with tap (potable) water.

Existing Paint Coatings:
Roughen the surface and/or treat with alkali. Carefully remove all unstable coatings.

Method of Application

Guidelines for Spray Application:

Equipment	Ø Nozzle	Spray Angle	Pressure	Dilution
Airless	0.012 - 0.014 inch	40 - 60 °	200 - 220 bar	undiluted
Caparol-NAST /Wagner XVLP FinishControl 5000	Caparol NAST-Frontend (Colour: blue)	-	full air quantity	10 % with tap water

Prefer spray application for corrosion protection conforming to standards. Check the thickness of the wet film with suitable gauge to achieve/ensure the necessary dry film thickness. 
On large, seamless areas a "clouding" effect may occur with spray coating and is sometimes unavoidable, due to sectioning surfaces in several operation segments.

Surface Coating System

Substrate	Use	Substrate Preparation	Priming Coat	Intermediate Coat	Finishing (Top) Coat
Iron, steel	interior/exterior	derust/degrease	Capalac Aqua Metallschutz	if necessary: Capalac Aqua Metallschutz	Capalac Aqua Metallschutz
Zinc (galvanised steel)	interior/exterior	BFS No. 5
Aluminium	interior/exterior	BFS No. 6
Copper	interior/exterior	Multistar/abrasive pad
Stable existing paint coatings1)	interior/exterior	roughening/alkali treatment	Prepare and prime defective areas depending on substrate requirements

Note: Adhesion must be tested in advance for powder coatings, coil coatings and other critical/problematic substrates by trial coatings on site.

Application:
Capalac Aqua Metallschutz can be applied by enamel brush, roller or spraying equipment. Stir thoroughly before use. Spray application should be used to achieve the necessary wet and dry film thickness and protection against corrosion conforming to standards (see following tables/corrosivity categories.

Adhesive Tapes to Limit the Coating: 
Remove all adhesive tapes before the coating (film surface) is dry. Otherwise the coating will be raised in border areas, due to the high dry film thickness. Use waterproof adhesive tapes.

Explanations
Corrosivity categories (see DIN EN ISO 12944 Part 2)

Category/ Load	Examples for typical ambient conditions or loads in temperature zones.
	exterior	interior
C2 low	Atmospheres with a low pollution. Mostly rural climate.	Unheated buildings, facilitating condensation, e.g. store-rooms, sports halls.
C3 modest	Urban and industrial climate, modest pollution caused by sulphur dioxide. Coastal regions with low contamination/stress due to salt-water.	Production facilities with high moisture and some air pollution, e.g. facilities for food production, laundries, breweries, creameries.
C4 strong	Industrial areas and coastal regions with a modest contamination/stress due to salt-water.	Chemical installations, swimming pools, boathouses above sea.

Durability of Protection
(See DIN EN ISO 12944 Parts 1 and 5)
Anticipated period of a coating system (durability) before the first maintenance is required. The given time intervals are experiences that may be helpful for building owners to state a repair schedule under economic considerations.
Durability is no warranty period!

Time Interval	Durability (Years)
