Spray-On Waterproofing
one-component cationic emulsion
AVIRON
Sprayable rubber is a spray-application high
viscosity bitumen and highly elastic polymer, solvent-free
Property profile:
AVIRON
Sprayable rubber is a bitumen rubber coating based on a cationic
emulsion
AVIRON
Sprayable rubber is a highly-safe
waterproofing material with excellent product properties.
AVIRON
Sprayable rubber is an environment- friendly,
solvent-free waterproofing material with highly crack-bridging properties and
water-proof within a very short period of time.
AVIRON
Sprayable rubber creates after drying a high elastic top layer
with optimal adhesion to bituminous surfaces

Drying
time Depends on weather conditions. In good drying weather, the
drying time is approx. 8 hours

TEMPERATURES BELOW - 30 °
Use (PP 306 DR A) min
Range of use:
Recoverable and
preventive maintenance of disintegrated roofs. Application is possible on flat and sloped roofs.
AVIRON Sprayable rubber is used on modern modified
roofing felt. Because AVIRON Sprayable
rubber is free of solvents there will
be no softening of the subbase.
Also available
for areas with winter temperatures below -30 C° ( PP 306A)
Substrate:
The
surface to be treated must be free of dust, oil and grease.
Cut blisters and repair
with fibreglass sheeting
Working directions:
AVIRON Sprayable
rubber must be applied by specially trained
operatives who apply Sprayable rubber evenly in the desired thickness
Do
not apply AVIRON Sprayable rubber at temperatures below + 5 °C or during
strong wind or rain. immediately after
application slate chippings will be strewn in the wetproduct
or use special sealing sand projected in the surface with the special
application machine. After totally drying the excess slate chippings or sealing
sand can be removed.
It adheres to practically all subsur-faces used in construction, such
as roofing sheet, cellular and
standard concrete, plaster, masonry and even timber. Once fully dry, the elasticity of the product means that any hairline cracks occurring in the subsurface are permanently
bridged and sealed.
APPLICATION
The use of AVIRON Sprayable
rubber as a
waterproofing measure is only possible in combination with a special modified
air-less spraying machine.
renovation of old roofing
Little or no
defects in the old covering:
the surface should be
free of dirt and other loose particles. blisters and folds should be cut out and repaired with
roofing felt or AVIRON SPRAYABLE RUBBER with an open fibre felt. prime with a brush
joints and cracks must be treated with roofing felt or
polyester bedded in AVIRON
Sprayable rubber .
depending on the quality of the existing covering 1 or 2
layers of AVIRON Sprayable rubber is applied approx 1 ,25 kg/m2 per layer.
finish off with special Sealing sand or slate chippings
Aged
roofing but little or no defects:
Pre-treatment and finishing as mentioned above,
only an open tissue or felt is embedded in the first layer Of AVIRON SPRAYABLE
RUBBER . After drying, a second layer of AVIRON Sprayable
rubber is applied in a thickness of
approx 2-2.5 kglm2.
Roofing
with many defects:
After cleaning and repairing a layer of perforated
bituminous open fibre felt is loosely laid. Next a layer of AVIRON Sprayable
rubber [1 ,25
kglm2] is applied with open tissue or felt directly in the AVIRON Sprayable
rubber.
After curing a second layer of AVIRON Sprayable
rubber is applied. Then finish off.
Of course there is also the possibility of
repairing and adhering according to the slinger
method with cold adhesive and/or bitumina of roofing
felt, before applying AVIRON Sprayable rubber.
Finishing
Flat
roots: Always
finish with special sealing sand or slate chippings.
Sloping roofs: On sloping roofs a finishing layer is recommended
as well: A choice can be made from special sealing sand or
waterproofing of balconies and Terraces
Small surfaces and
low water load : one layer with a thickness and 1.5
-1.8 kg/m2. To make the surface trafficable sand in wit coarse sand.
Then tiles of
concrete can be laid on top of this.
Waste

When the surface
is hand dry apply 3 layers and wait approx 8 Hr between layers
Making sure the
product does not drip ( it is better to use multiple
thin layers than one thick )

Masonry joints must be full and well bound. After
cleaning, making dust free and priming.
AVIRON SPRAYABLE RUBBER is
dressed with dry sand
to facilitate tiling.
use:
on vertical surfaces 2 layers of 1.0 kg/m2
on horizontal surfaces 2 layers of 1.5 kg/m2
In dusty rooms use of a bituminous primer AVIRON- DR
is advised before applying AVIRON Sprayable rubber.
Sealing floors from earth gas penetration ( underground gas penetration )
Heat the PP306 DR to
Apply evenly and allow to cool
down using approx 3 Kg/M²
Cover with concrete with a min thickness of
waterproofing cellar walls, foundations
against moisture pulling up: 2 layers of 1.0 kg/m2 each.
against ground water: 2 layers of 1.5 kg/m2 with tissue. etc. then cover with earth.
Tools and cleaning:
Special
modified air-less spraying machine, paint brush, brush,
roller.
In fresh
condition the tools may be cleaned first with water and clean thoroughly with gasoil. ( Diesel)
Hardened
material can be removed with V 100.( Thinner)
