Van Gogh h2oil colour is an oil colour
with very special characteristics, the paint can simply be thinned
with water and has a very short drying time. It is no longer necessary
to use solvents or lots of mediums. As a result, Van Gogh H2oil colour
is particularly easy to use and is also environmentally friendly, while
the finished painting retains the appearance of a regular oil colour.
Van Gogh H2Oil Colour dries much faster than ordinary oil colour.
In thin layers the paint can normally be overpainted after a single
day. The colour completely retains the brush strokes as with traditional
oil colours. The range consists of 40 brilliant and lightfast colours,
using pigments which do not contain toxic, heavy metals. The colours
are very brilliant and do not change colour during drying.
The well known oil techniques such as wet-on-wet and layered painting
can be easily carried out with this colour. All substrates which
are suitable for oils can also be used for Van Gogh H2Oil Colour.
The best known are oil paint paper, canvas board and prepared canvas.
TIPS ON USAGE
The Water-Solubility
Van Gogh H2Oil Colour is a pure oil colour. The paint itself does not contain
water. This means that there is no loss of brush stroke and no change in
colour during the drying process. If water is added to the paint, the water
will evaporate (just like white spirit when used with traditional oil).
To achieve a homogenous mixture when
mixed with water the paint should be emulsified little by little.
The emulsion is not formed automatically when water and paint are
making contact, but must be activated. One must put some effort
in the process. A small quantity of paint is mixed thoroughly with
a wet brush. By adding small quantities of water or paint and good
mixing a homogenous emulsion will be formed.
If one stirs with a wet brush in a pile of paint, only that part
of the paint will be connected with water where pressure with the
brush has been exerted. The mixture will be partly thinned and partly
not emulsified and therefore not thinned. The mixture will not be
homogenous. Thinning thoroughly and little by little avoids this
problem.
The Drying Process
The drying process of Van Gogh H2Oil Colour
is similar to that of traditional oils. It is a chemical process,
caused by oxidation under the influence of air and light (oxygen
and UV). Van Gogh H2Oil Colour is a fast drying oil colour. The drying
time is much shorter than with traditional oils, but also much longer
than with acrylic colours. There is still sufficient time to use
wet-in-wet techniques. Just like with traditional oil colours the
drying time depends on the kind of pigment and the air humidity.

TECHNIQUES AND POSSIBILITIES
Van Gogh H2Oil Colour is a genuine
oil paint, so all techniques suitable for oil colours can be
practised (such as wet-in-wet, impasto, painting in layers, glazing
techniques). Just like traditional oils it is essential to paint “fat
over lean” when painting in layers. For glazing techniques Talens
has developed a special water-soluble medium.
DURABILITY
The durability of paintings made with
Van Gogh H2Oil Colour is comparable with traditional oils. Wrinkling
of the paint in heavy layers does not occur.
MIXING
INSTRUCTIONS WITH OTHER PAINTS
Van Gogh H2Oil Colour can be mixed with
traditional oils. However, the water solubility will decline and
the drying time will be prolonged depending on the proportions
of the two types of paint. Van Gogh H2Oil Colour can also be mixed
with other water-soluble artists’ paints and mediums, such
as acrylic colours and acrylic mediums. But some of the typical characteristics
of oil paint, such as brush stroke, consistency and no change of colour
during the drying process, will change. To which extend depends
on the quantities in which the different paints are mixed. When
Van Gogh H2Oil Colour is mixed with another water soluble paint,
the substrate must still be prepared for the adherence of oil colour.

BRUSHES
All brushes that are suitable for oil
colours can also be used for Van Gogh H2Oil Colour. Brushes must
be cleaned with water and a little soap. This must be done the same
day because of the shorter drying time of the paint.
GROUNDS
For Van Gogh H2Oil Colour all substrates
used for oil paint are suitable, such as universally prepared canvas
and oil colour paper. All substrates must be prepared with a universal
primer. Talens Gesso is a perfect primer for Van Gogh H2Oil Colour.
SOLVENTS
AND MEDIUMS
Talens has developed a special water-soluble
medium called Van Gogh H2Oil Colour Medium. This medium makes the
paint “fatter” and improves the
flow. Used as a normal painting medium the medium should be thinned with
water, 50% water/ 50% medium. Used in the last layers as a glazing medium
the medium can be used pure. The drying time of the faster drying colours
in the assortment will slightly be increased by the medium.
All traditional solvents and mediums for oil
paint can be used with Van Gogh H2Oil Colour. However, the water-solubility
of the mixture will decline rapidly. If a solvent is used instead
of water, the drying time will remain unchanged. If a traditional
medium is used the drying time will be prolonged.
VARNISHES
When the painting is 100 % dry (also inside the paint layer) you must preserve
it with a varnish for oil colours. This full drying process takes approximately
one year.
PACKAGING
Van Gogh H2Oil Colour is available in 40 colours in 20 ml and 40 ml tubes.
The 20 most important colours are also available in a large 150 ml tube.
