Technical characteristics
TRAVERTINO ROMANO by OIKOS is a special decorative
coating, for interiors and exteriors. The product, which
is ready to use, is based on sand, selected marble
powders and matured lime putty and presents itself as a
homogeneous paste that is easy to apply and through the
correct technique, allows the realisation of a stone effect
that highlights the veins and texture of natural stone. One
of the main characteristics of the product is that of bonding
with the surface in such a way as to create a single body.
TRAVERTINO ROMANO prevents the development of
mould, algae and bacteria. It has a low odour level,
is non inflammable and is friendly to both humans
and the environment.
Ideal use
Exteriors and indoor surfaces.
Surface preparation
Surfaces must be thoroughly dry and mature. New plasters
should have matured for at least 30 days to allow for the
complete carbonation of the plaster. Clean the surface to
be coated, removing any loose or crumbling material. For
old or powdering surfaces, it is advisable to apply one coat
of the fixative NEOKRYLL by OIKOS. On all other types of
surface, apply one coat of the fixative BLANKOR by OIKOS
in order to render surface absorption homogeneous.
Application method
Spread TRAVERTINO ROMANO over the surface using an
inox steel trowel by OIKOS (art. 113 by OIKOS), leaving
a thickness of approxiamtely 1,5 ÷ 2,0 mm. Following this
immediately proceed to work TRAVERTINO ROMANO by
dabbing the surface, using the indicated tool (art. 133 by
OIKOS), in order to create the irregular veins of Travertine
stone. On the remaining areas, dimple the surface in an
irregular fashion using the same tool. Once the product
has started to dry, proceed to smooth over the surface for
the first time, using an inox steel trowel,compacting the
most evidently dimpled patches. When the surface of the
product is nearly completely dry, repeat the smoothing
over of the surface using greater pressure until the surface
is smooth in large areas with dimpled veins running across
it that imitate the veins of Travertine stone. To reproduce
the joints between the various blocks, once the surface
has been smoothed over and compacted, score into the
surface of TRAVERTINO ROMANO, using the corner of
the Small spatula for Raffaello by OIKOS art. 111 (or a
screwdriver) thus obtaining a block design of the desired
dimensions. To obtain a straight line, use a wooden plank
as a guide. Leave the product to dry for at least 24 hours
before proceeding with the application of the finish.
Finish
• TRAVERTINO ROMANO natural:
to protect and maintain the natural effect of TRAVERTINO
ROMANO, apply by brush, one coat of un coloured
TRAVERTINO ROMANO FINITURA ready for use.
• TRAVERTINO ROMANO with a coloured finish:
apply by brush, one coat of un coloured TRAVERTINO
ROMANO FINITURA ready to use, taking care to apply
the product only over the smooth areas of the surface and
avoiding that it penetrates into the dimpled areas that
recreate the veins of Travertine. Wait until the first coat
of the finish is dry and then proceed with the application
of the second coat of TRAVERTINO ROMANO FINITURA
in the chosen colour, diluted 50% with drinkable water.
Eliminate any excess product using a sponge to obtain a
light - dark effect, caused by the differences in absorption
between the smooth areas of the surface and the dimpled
areas that recreate the veins of Travertine.
Toner for Finitura: to obtain the desired shade from
the colour chart, mix 100 ml of TONER with 1 litre of
TRAVERTINO ROMANO FINITURA and mix thoroughly.
