001 metallicote® Brass Powder

Irregular brass powder produced by water atomisation. 

A mixture of metal powder and polymer binder (with activator) is sprayed onto sheet material or an object and then finished to give both the look and feel of brass.

Techniques to produce the desired effect can include grinding, sanding and polishing.

Mixing ratio

• 1ml lacquer : 2.6g metallicote® Brass
• e.g. 5L lacquer : 13.0kg metallicote® Brass

Preparation

• Timber/MDF: seal with 1 or 2 coats of VLi® 6004/460 clear sealer
• Plastic: adhesion promoter recommended, contact Technical Support 0161 406 5300
• Allow to dry for a minimum of 2 hours

Mixing

• Mixing mechanically, add powder slowly to catalysed metallicote® Binder 6884/460
• Thin to application viscosity using fast, medium or slow thinners

Textured effects

• Apply thin background coat of metallicote®
• Fine texture - use unthinned catalysed metallicote®, reduce fluid supply to gun and reduce air pressure to apply splatter coating
• Coarse texture - same technique as above, with a larger fluid tip
• For textured effects allow metallicote® to dry overnight before sanding/finishing

 Sanding

• May be carried out with hand sander or machine
• Sand edges carefully to prevent sanding through the coating
• Start with 320 grit, then 400 grit, finish with coarse and fine wire wool
• Always test coarseness before application

Final finishing

• Brushed effect - use wire wool, work from coarse to fine grit until effect is achieved
• Swirling effect - use wire brush on a drill

Final coat

• If desired, seal metallicote® with a thin coat of clear base lacquer, ensure coating thickness is as thin as possible to prevent loss of metallic feel
• For exterior use, metallicote® must be sealed with appropriate exterior grade lacquer

Verdigris or patina effect

• Normally applied to sanded finishes
• Spray the area(s) where the effect is required with a mist coat of Patina Solution #1
• Spray over the Patina Solution #1 with a mist coat of Patina Solution #2
  
• Spray a further mist coat of the Patina Solution #1
  
• Heavier applications will give a heavier/denser verdigris effect
• Leave to dry, the verdigris effect will appear
• Verdigris in unwanted areas may be removed with fine wire wool or 320 grit sandpaper

Burnt effect

• Spray the area(s) to be burnt with a mist coat of Patina Solution #3
• Spray over the Patina Solution #3 with Patina Solution #4
• Remove excess liquid by dabbing with a dry cloth
• Repeat until the required degree of burn is achieved
• Dry with a clean cloth
• Seal with clear lacquer within 5 minutes, to prevent increasing the burn effect
