Bauder’s new LiquiTOP System oers a competitive
overlay solution for refurbishing flat roofs
Bauder has launched a cold-applied moisture-triggered polyurethane (PU) liquid waterproofing system,
which has been specifically designed for use on projects that require a value for money solution with a
comprehensive guarantee. The company reveals more to RCI readers
Bauder has developed a BBA
certified, liquid-applied
waterproofing system, which is
suitable to install on a variety
of substrates, providing flexibility for
complex roof areas, whilst maintaining
manageable costs and quick installation
times.
Bauder LiquiTOP System Cold
Applied Roof Waterproofing has
an option for a two coat or three
coat solution to match the client’s
expectations for durability, lifespan,
and guarantee duration. Importantly,
the system has been tested and meets
current fire regulations.
Mike Bradbury, product manager for
cold-applied liquid systems at Bauder,
said: “The LiquiTOP System is a terrific
flat roof waterproofing solution that has
many benefits for roofing contractors,
installers and clients. It is quick to install
and forms a monolithic membrane
that contours to detailing and the roof
shape, making it ideal when a roof area
presents challenging elements.
“On refurbishment projects where
the current roof is sound and does not
require stripping, minimal waste is
generated as overlaying is a solution
for when the project requires a rapid
turnaround with minimal disruption to
the occupants.
“Roofing contractors will
be interested to know that an
unopened LiquiTOP PU product
retains its optimum usability
over its whole shelf life and does
not thicken in the tin over a few
months.
“LiquiTOP PU uses the latest
curing technology with the added
benefit of improved in-can stability,
which means that the unopened
product retains its optimum usability
throughout its stated shelf life.”
System components and
installation
Key components of the Bauder
LiquiTOP System include:
• LiquiTOP PU Dark Grey liquid
membrane
• LiquiTOP PU Mist Grey liquid
membrane
• LiquiTOP Glass Fibre Mat
• A range of four LiquiTOP primers to
suit the material the PU is bonding to.
Starting at the details, an
embedment coat of LiquiTOP PU is
applied and reinforced with LiquiTOP
which mitigates any risk from fire
on-site during installation.
• A single component system – No
complicated mixing or measuring of
the PU is needed, making it easier
for the operative to use and create a
cleaner installation on-site.
• Monomer stripped prepolymer is
a safer product for installers – The
low-monomer technology system
is compliant to the Classification,
Labelling and Packaging (CLP)
Regulation, thereby providing a
safer working environment for the
operative.
• Moisture triggered curing – The
LiquiTOP System tolerates some
substrate moisture, allowing for a
longer window of installation.
• Conformable glass fibre reinforcement
– The 225g/m2 LiquiTOP Glass Fibre
Mat forms to roof undulations and
details, making it easier to apply to
existing roofs.
• Competitively priced – The LiquiTOP
System is a cost-effective solution,
with the well-known Bauder
support available, thereby giving
the competitive edge when going to
tender.
• Simple application technique –
Complex roofs will be easier to
complete and therefore labour costs
will be reduced, further lending
a competitive edge when it comes
to pricing jobs. The wet-on-dry
application allows for a larger roof
area to be installed, and provides
a temporary waterproof covering,
rather than having to complete
smaller areas fully with a wet-on-wet
system.
• Minimal disruption – Buildings
can usually remain in use with
little or no disturbance because
the LiquiTOP System can overlay
existing substrates, and has a lower
odour than some other polyurethane
systems. Overlaying also means
a quicker and more economical
project, saving the labour involved
in stripping the roof and the cost of
disposing waste materials from site.
• Bauder guarantee – The
comprehensive Bauder guarantee
provides peace of mind for clients and
building owners.

Glass Fibre Mat. Then the main
roof area receives an embedment
coat with reinforcement, and the
installed areas are left to cure,
usually overnight.
At this stage, the completed
reinforced embedment coat acts as
temporary waterproofing. The topcoat
is then applied wet-on-dry to the cured
embedment coat, again, starting at the
details and then proceeding with the
main roof area.
The LiquiTOP PU delivers superior
adhesion between layers, as well as
to most deck structures or existing
waterproofing that requires an overlay
solution, including concrete, reinforced
bitumen membranes, liquid-applied
membranes, PVC single ply and asphalt.
Benefits of the system
• No hot works for application – The
Bauder LiquiTOP System is a cold-
applied waterproofing solution,
