Pentart patina effect set: 20 g powder + 3 × 20 ml

Build an aged copper patina effect on decorative objects using powder and three reactive liquids. Alternating the drops produces green and blue tones with varied, irregular transitions.

What is included?

The set contains 20 g of patina effect powder and three 20 ml reagents: green, bluish-green and light blue. The liquids react with the powder to create the decorative finish.

How to build the effect

Apply an even layer of light-coloured primer paste or gesso, or use Pentart self-adhesive, repositionable hobby glue. Gently press the powder into the still slightly moist layer with a brush. Do not mix the powder into the base coat or apply too much.

Apply drops of the three reagents alternately onto the powder. Let the colours meet and soften their boundaries with a soft brush. The reaction starts immediately; the final colour effect develops after 24 hours.

Start with a sample

Try your chosen surface, base coat and distribution of drops on a sample first. The amount of powder and liquid, and the places where the colours meet, shape the pattern. Expect a varied effect rather than a completely uniform colour.

What else will you need?

Primer paste or glue, brushes and protective equipment are needed separately. Explore our effect paints too. To build a patina effect using five acrylic paint colours, see the Pentart 5 × 20 ml patina effect acrylic paint set, a different set with a different application method.

Working safely with the reagents

Danger. The reagents may be corrosive to metals and cause severe skin burns and eye damage. They contain nickel sulphate and may produce an allergic reaction. They are very toxic to aquatic life and toxic to aquatic life with long lasting effects.

Keep only in the original container and out of reach of children. Wear protective gloves, protective clothing, eye protection and face protection. Avoid release to the environment. Absorb spillage to prevent material damage.

If on skin or hair: take off contaminated clothing immediately and rinse skin with water or shower. If in eyes: rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, and continue rinsing. Immediately call a poison centre or doctor.

Working safely with the powder

Danger. Flammable solid. Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. Do not breathe the dust and wear the protection described above. In case of fire, use dry sand for extinction. Read the labels of all components before use.
