A sound investment
– minimises life cost
Sioo are leaders in wood protection using silicate technology. We provide a
highly effective proven system to protect wood of all types. It gives long life
and a beautiful natural surface with even colouration and is friendly to people
and the environment. An example of a Sioo project is Ålleberg High School, a
low energy building in Falköping, Sweden.

SiOO:X
SiOO:x is a patented (WO2007111556) silicon-based two-
part wood surface treatment process that was developed
in Sweden over 15 years ago, where it finds extensive use
in the DIY market. The surface protector acts to prevent
the wood protector from leaching out until it has cured.
The wood protector undergoes a chemical reaction with
atmospheric carbon dioxide to deposit insoluble silica
particles in the wood. Light scattering from the silica
particles gives and even silvery-grey appearance to the
wood surface, looking just like weathered wood. The
silica envelope that forms is completely stable to ultra-
violet light, unlike oil and varnishes, which are based on
carbon chemistry. It is the even-ness of the silvery-grey
appearance that is one of the most attractive features of
the product. But the product needs to be applied correctly
in order to obtain optimum performance. Factory finishing
is always to be preferred because the product can be
applied under controlled conditions. The product works
best when there is good penetration of the wood material
and rough sawn surfaces are always preferred. Where
planed surfaces are specified it is important to sand the
surface to break through the machining glaze that is often
present in order to allow the product to penetrate the
wood. Curing is also accelerated with higher temperatures,
but applying in direct sunlight is best avo ided, since rapid
drying of the water-based product will limit diffusion into
the wood. Application in damp, cold conditions is also to
be avoided, since curing is slowed down and there is a risk
that the wood protector will be leached out before curing
has occurred. For these reasons a factory-applied finish by
a SiOO:x accredited treater is always the best option. The
treatment can be applied using brushing or spraying and
good penetration is the key to good performance.
