In any tiled wet area, there is a risk of leaking. Leaking can be caused
by poor installation, incorrect waterproofing, damaged tiles, or
compromised grout structure – but whatever the cause, the solution is
usually to rip it all up and replace it. Obviously that’s a very expensive,
messy and time-consuming remedy! However now for the first time
ever there is a product that can fix the leak without replacing the tiles.
What’s the best way to prevent a leak?
Prevention is always better than cure, and in the case of tile
installation, it pays to get an experienced professional to complete any
tiling work. This is especially the case when the tiles are being installed
in a wet area such as showers, bathrooms and outdoor balconies.
Waterproofing a surface is vitally important, both UNDER and
ON TOP OF the tiles. Underneath the tiles proper waterproofing
involves laying a waterproof membrane as a complete barrier to water
penetration. On top of the tiles, waterproofing involves application of
a suitable sealer for the surface to inhibit water penetration.
My tiles are damaged, what should I do?
Act quickly! The faster you address the damage, the less likely you are
to experience a major leak. In the case of compromised grout or broken
tiles, replace it as soon as you notice that it has been compromised.
What is the white/yellow crusty
build-up on my tiles?
Efflorescence. Basically efflorescence is the visible sign that you have
a leak, and water is entering the surface. It’s caused by mineral salts
that are dissolved in the water, and then as the water evaporates the
salts are left on the surface. The white or yellow crusts are extremely
difficult to remove, and will keep on recurring until the leak is fixed
and no more water can enter.
Efflorescence may not always be present when there’s a leak (as it
requires the presence of mineral salts and water) but where there’s
efflorescence, there’s a leak.
Common myths debunked
Myth #1: single membrane waterproofing will prevent efflorescence
In a single membrane waterproofing system, the membrane is laid
underneath the screed, which is often a source of salts. If water gets
through the top of the installation, it can still activate the salts and
cause efflorescence, even though the membrane is still intact.
By comparison, a double membrane waterproofing system adds an

additional membrane on top of the screed. The building code only
requires a single membrane waterproofing system to be used, however
a double membrane will provide much more protection in a wet area.
Myth #2: grout and tiles are a source of efflorescence
This is extremely rare. Most brand-named grout and glue systems are
guaranteed to be free from efflorescence salts. Porcelain tiles are inert,
so there’s no chance they could be a source of salts. Other stone types
may contain salts, however they are within the stone itself rather than
being released through the water/evaporation process, so they don’t
show as a white calcium encrustation.
How can I fix the leak without
replacing the tiles?
Use Fila’s product Salvaterrazza. Literally ‘save my terrace’, it
penetrates into the material, consolidating the surface. Salvaterrazza
penetrates into cracks up to 1mm wide, making them water repellent,
thereby eliminating the problem of water seepage, preventing the
formation of mould and efflorescence, and protecting against further
serious structural damage.
Salvaterrazza is simple to use and quick-acting. A small can gives a
high level of coverage. The product doesn’t create a surface film (so
it’s invisible) and it allows the stone or tiles to breathe. It won’t yellow
even with aging or environmental conditions.

minutes during the C. diff. trials. As reported in Infection Control and
Hospital Epidemiology, the use of UV-reflective coatings significantly
improved the performance of the device. This improvement was
most pronounced on surfaces that would normally be shadowed. For
example, Lumacept helped increase the log-reduction for all surfaces
from 3.56 to 4.50 for MRSA, but for indirect (shadowed) surfaces the
improvement was even greater: from 2.74 to 4.21.
Because UV light is invisible to humans, it’s simply not possible for us
to see where the light is hitting and where it is not. However, scientific
measurements tell us that the UV received by a hospital room surface
varies greatly based on the location and orientation of the surface. It is
also strongly dependent on the location of the device. For these reasons
it is difficult to know exactly where a device should be located and
how long it should be run in order to achieve the greatest disinfection
in the shortest total time. Unfortunately, generic recommendations
from device manufacturers often fall short of this goal, as they cannot
possibly account for all the variations in size, shape, and layout.
As the adoption of UV disinfection continue to grow, so does
the body of research into how to best use this technology. Here we
have highlighted two recent advances: UV-reflective coatings and
predictive computer simulations. Together, these developments allow
a healthcare facility to get the maximum return on their investment in
a UV device.
