Restoration product brings Sydney's Central Station sandstone facade back
In April 2008 Railcorp began a major project to refurbish the sandstone facade
of Central Station. Part of the process involves using a unique NSW developed
product called Cocoon that removes salt and contaminants and halts further
deterioration. Cocoon is manufactured by Revesby-based company Westox.
The project is being overseen by RailCorp's Central Precinct Manager Glen Green
who says that the improvements he has already seen are very obvious.
"Central Station was originally built in 1904 and then added to in 1926 so it
has seen over one hundred years of dirt and grime from trains and cars that pass
by each day.
"We had planned to upgrade the lighting on the outside of the station to
highlight the sandstone but the treatment has brightened the facade so much the
additional lighting is no longer required," Green said.
"An added benefit has also been the removal of any chemical residue that
remained on the sandstone after graffiti removal. Over many years the graffiti
has been removed using solvents or highly alkaline strippers and high pressure
hoses and the sandstone has been damaged. We plan to use a modified Cocoon
(D-Lam 20) for our ongoing graffiti removal," he added.
Stage One of the refurbishment of Central Station was carried out by Heritage
Building Services and overseen by architects Otto Cserhalmi. The total project
is to be carried out in five stages and will take place over three to four years
and cost $8 million.
Cocoon is the brainchild of Westox Managing Director Barrie Cooper who spent the
early part of his career as a plasterer. Cooper recognised the need for a
product to remove salt from masonry and developed the product initially to treat
salt contamination at Fort Denison on Sydney Harbour.
Cocoon works by drawing the salt out of the masonry it is applied to. Cocoon is
sprayed or trowelled on in a 10mm thick layer where it slowly releases water
into the masonry to place the build up of salts in the surface of the wall into
solution. As the cocoon dries, the water containing the salts is drawn into it.
The cocoon is then removed, along with the salt.
