polystyrene that has a minimum compressive strength of 8 lbs/
in.
2
(55 kN/m
2
). Such alternatives do not provide positive
drainage to the system. If
1
⁄
4
in.
(6 mm) extruded polystyrene protection board is used, back-
ll should not contain sharp rock or aggregate over 2 in. (50
mm) in diameter. Adhere polystyrene protection board with
Preprufe
®
Detail Tape.
• In mud slab waterproong, or other applications where positive
drainage is not desired and where reinforced concrete slabs are
placed over the membrane, the use of
1
⁄
4
in. (6 mm) hardboard
or 2 layers of
1
⁄
8
in. (3 mm) hardboard is recommended.
Insulation
Always apply Bituthene
®
membrane directly to primed or condi-
tioned structural substrates. Insulation, if used, must be applied
over the membrane. Do not apply Bituthene
®
membranes over
lightweight insulating concrete.
Backll
Place backll as soon as possible. Use care during backll
operation to avoid damage to the waterproong system. Follow
generally accepted practices for backlling and compaction.
Backll should be added and compacted in 6 in. (150 mm) to 12
in. (300 mm) lifts.
For areas which cannot be fully compacted, a termination bar is
recommended across the top termination of the membrane.
Placing Steel
When placing steel over properly protected membrane, use
concrete bar supports (dobies) or chairs with plastic tips or rolled
feet to prevent damage from sharp edges. Use special care when
using wire mesh, especially if the mesh is curled.

Maintenance
The Bituthene
®
System 4000 Surface Conditioner Sprayer
should perform without trouble for an extended period if
maintained properly.
Sprayer should not be used to store
Bituthene
®
System 4000 Surface Conditioner. The sprayer
should be ushed with clean water immediately after spray-
ing. For breaks in the spray operation of one hour or less,
invert the sprayer and squeeze the spray handle until only air
comes from the nozzle. This will avoid clogging.
Should the sprayer need repairs or parts, call the maintenance
telephone number on the sprayer tank (800-323-0620).
Bituthene System 4000 Surface
Conditioner Sprayer
The Bituthene
®
System 4000 Surface Conditioner Sprayer is
a professional grade, polyethylene, pump-type, compressed
air sprayer with a brass fan
tip nozzle. It has a 2 gal (7.6 L) capacity. The nozzle orice
and spray pattern have been specically engineered for the
optimum application of Bituthene
®
System 4000 Surface
Conditioner.
Hold nozzle 18 in. (450 mm) from substrate and squeeze
handle to spray. Spray in a sweeping motion until substrate is
uniformly covered.
Sprayer should be repressurized by pumping as needed. For
best results, sprayer should be maintained at high
pressure during spraying.
To release pressure, invert the sprayer and spray until all
compressed air is released.
