MAINTENANCE
JATOBA
Jatoba wood requires little or no
maintenance. However, we strongly
advise you to remove persistent dirt.
To clean the wood you can use special
products (www.rmc-extremis.be) or
simply a stiff bristle brush and some
water. Be careful not to irreparably
damage the wood fibres. For this
reason,
never use a high pressure
cleaner as this will roughen
the wood’s smooth surface and
irreparably damage the wood’s
fibres.
At first, the wood will give off this red
dye every time it comes into contact
with water. The dye that drips onto
the frame and the surface will remain
water-soluble and will dissapear
entirely after a while.
We strongly recommend that you
treat your wood for indoor use with
wood oil to protect it from stains.
When delivered, the wooden parts of
our products are
untreated . Exposure
to sun and rain will gradually change
their colour to silvery grey, and also
roughen the surface. If you want
to somewhat retain their original
colour, you should oil them once a
year. We recommend using
RMC
Hybrid Wood Protector (www.rmc-
extremis.com). RMC products for
wood treatment are available all over
the world. Visit the website www.

IMPORTANT!
Wood is a living matter and, in spite
of the superior quality provided
by jatoba, outdoors it constantly
has to adapt to extreme changes
in temperature and humidity.
Due to internal stress resulting
from these constant adaptations
the wood “warps”. This warping
can among other things lead to
cracking. Changes in colour or
wood structure may also appear.
These characteristics are typical of
the material and by choosing this
material you accept them.
Should any cracks appear, you can
simply sand them down either by
hand using sandpaper or by means
of a hand sander. To protect any
galvanised or painted parts, cover
the edges with highly robust masking
tape. Use 80-grit sandpaper and start
at the vertical side of the tabletop.
Keep the hand sander parallel to the
edge of the tabletop. Lightly sand
the edge until it is smooth again.
Now sand the rest of the tabletop.
Make sure that you always hold the
hand sander parallel to the tabletop.
Do not only sand the crack, but the
entire tabletop to obtain a uniform
result. To avoid burrs, sand the top
edge of the tabletop by hand. When
you have removed all the burrs, you
can treat the wood with hardwood
furniture oil or leave it untreated,
depending on the desired effect.
ALUMINIUM
The profiles used for our “ExTempore”
range are made of extruded and
anodised aluminium. Anodising is
a process aimed at thickening the
existing aluminium oxide layer,
which protects the aluminium
from rusting. We have opted not to
submit the aluminium to any further
treatment as this does not alter its life
span and is moreover very harmful
to the environment. It is there fore
possible that the profiles present
minor scratches or scores, resulting
from the production process. These
do not in any way detract from the
material’s durability. The profiles
require little maintenance. Cleaning
them with lukewarm water and a
mild detergent once or twice a year
is sufficient.
STAINLESS STEEL
Although stainless steel has its own
oxidation layer protecting the steel
from rust, it remains necessary
to regularly remove deposit and
dirt from the steel with a dry cloth
and some stainless steel cleaner. If
damaged, the oxidation layer cannot
always repair itself completely. A
maritime climate, bleach, acid rain,
an aggressive industrial or urban
environment seriously damage
the material. They determine the
frequency and the necessity of the
surface cleaning. The appropriate
cleaning products are readily
available. Steel will however only
remain rustproof if it is covered by
the oxidation layer. Consequently,
you must prevent the formation of
a permanent layer of dirt, especially
in case of aggressive environmental
factors.
