DESCRIPTION
2K patina
solutions are water based metal salt solutions based on historical formulations
for use by the modern day patina artist.
These solutions allow the natural process of patination on colored
metals that naturally occurs over great time periods to be accomplished in a
substantially shorter time frame with more predictable results.
2K Verdigris
Green patina solution may be used directly on the metal surface or over 2K
Antique Black patina background.
APPLICATION
INSTRUCTIONS
SURFACE PREPARATION
It is important
to clean the metal before any coloring operation. Ensure that all oils, waxes, flux remnants,
mold release agents, and oxides are removed from the metal surface. The best
method of cleaning most materials is to sandblast. If this method is undesirable then non
residual solvents such as acetone, isopropyl or methyl alcohol, or lacquer
thinner are useful for removal of most oils and waxes. When grease is present clean the work with a
TSP solution or blend of ammonia, soap, and water.
2K Technologies
manufactures and recommends the use of 2K Metal Cleaner or 2K EcoBright Cleaner
for optimal performance. 2K Metal
Cleaner is a fast acting strong acid metal brightener for severe tarnish and
oxide removal. 2K EcoBright Cleaner
provides an effective organic acid based green alternative when fine detail may
be dissolved by use of strong acids.
When the metal is
thoroughly clean water will “sheet” or cover the whole surface rather than bead
up. Rinse the metal well and dry
thoroughly. From here on, handle the
work only by the edges. Apply patina
within 30 minutes.
PATINA APPLICATION
The patinas made
by 2K Technologies are ready to use and formulated to be applied at room
temperature. The method of application
depends on the size and shape of the work.
Do not allow patina solution to pool as heavy application results in
poor adhesion. Several light treatments
are recommended allowing solution to react and dry completely in between.
Note: the results will be affected by the
temperature of the metal, the temperature of the solution, and the duration of
exposure to the patina solution.
• Immersion into the patina solution. DO NOT RINSE the patina solution off after
removal from the bath.
• Spray the patina solution using spritzer. Be sure to clean the spray components after
use as any metal components will be attacked by the patina solution. Avoid inhalation of the mist.
• Brushing the patina on using brushes, sponges, wads of
cheesecloth, and other improvised tools to dab solution onto the metal.
• Create an airtight environment which would trap the chemical
vapor and allow the work to sit untouched until the desired effect is
achieved.
In all cases
allow the solution to react and dry. DO
NOT RINSE. The Verdigris Green patina
develops as the solution dries on the surface.
Reapply if needed to boost the patina color. The longer the Verdigris Green sits on the
metal (>30 days) the better the adhesion.
TOPCOAT FINISHING
Once the patina
finish is achieved it may be left to continue weathering naturally or be
arrested at this point by applying oil (linseed or lemon), wax, or urethane
lacquer. Urethane lacquer or wax coatings improve the resistance to scratching,
flaking and tarnishing. Oil and wax sealants
are regarded as temporary sealants and must be reapplied over time. In general, patinas on copper tend to be flakier, more sensitive and less durable over time (than patinas on silver or gold) even if you apply wax to stabilize and protect.
Note: any patina finishes used on a kitchen surface
or that will be handled frequently should be sealed with a nonporous sealer.
CAUTION
Patina solutions
are mild acidic solutions and can cause irritation to the skin and eyes. They are generally considered consumer
friendly and carry no special restrictions and require no special safety
precautions other than the normal effort to keep the liquid out of the eyes and
to avoid prolonged skin exposure. KEEP
OUT OF REACH OF CHILDREN! Rubber gloves
and safety glasses should be worn. Read
MSDS before using.
STORAGE
Product should be stored indoors in original closed container. To prevent
contamination of the solution, used product should not be introduced back into
the original container.
