• Overlap security—minimizes margin for error under site

conditions

• Cross laminated, high density polyethylene carrier lm—

provides high tear strength, puncture and impact resistance

• Flexible—accommodates minor structural movements and will

bridge shrinkage cracks

• Ripcord

—this split release on demand feature allows the

splitting of the release paper into two (2) pieces for ease of

Use

Bituthene

membrane is ideal for waterproong concrete,

masonry and wood surfaces where in-service temperatures will

not exceed 135°F (57°C). It can be applied to foundation walls,

tunnels, earth sheltered structures and split slab construction, both

above and below grade. (For above grade applications, see Above

Grade Waterproong Bituthene

System 4000.)

Bituthene

waterproong membrane is

⁄

in. (1.5 mm) thick, 3

ft (0.9 m) wide and 66.7 ft (20 m) long and is supplied in rolls.

It is unrolled sticky side down onto concrete slabs or applied

onto vertical concrete faces primed with Bituthene

System 4000

Surface Conditioner. Continuity is achieved by overlapping a

minimum 2 in. (50 mm) and rmly rolling the joint.

Bituthene

membrane is extremely exible. It is capable of bridg-

ing shrinkage cracks in the concrete and will accommodate minor

differential movement throughout the service life of the structure.

Application Procedures

Safety, Storage and Handling

Information

Bituthene

products must be handled properly. Vapors from

solvent-based primers and mastic are harmful and ammable.

For these products, the best available information on safe

handling, storage, personal protection, health and environmental

considerations has been gathered. Material Safety Data Sheets

(MSDS) are available at

graceconstruction.com and users should acquaint themselves with

this information. Carefully read detailed precaution statements on

product labels and the MSDS before use.

Surface Preparation

Surfaces should be structurally sound and free of voids, spalled

areas, loose aggregate and sharp protrusions. Remove contami-

nants such as grease, oil and wax from exposed surfaces. Remove

dust, dirt, loose stone and debris. Concrete must be properly dried

(minimum

7 days for normal structural concrete and 14 days for lightweight

structural concrete).

If time is critical, Bituthene

Primer B2 or

Bituthene

Primer B2 LVC may be used to allow priming

and installation of membrane on damp surfaces or green

concrete. Priming may begin in this case as soon as the

concrete will maintain structural integrity. Use form release

agents which will not transfer to the concrete. Remove forms as

soon as possible from below horizontal slabs to prevent entrap-

ment of excess moisture. Excess moisture may lead to blistering

of the membrane. Cure concrete with clear, resin-based curing

compounds which do not contain oil, wax or pigment. Except

with Bituthene

Primer B2 or Bituthene

Primer B2 LVC, allow

concrete to thoroughly dry following rain. Do not apply any prod-

ucts to frozen concrete.

Repair defects such as spalled or poorly consolidated areas.

Remove sharp protrusions and form match lines. On masonry

surfaces, apply a parge coat to rough concrete block and brick

walls or trowel cut mortar joints ush to the face of the concrete

blocks.

Temperature

• Apply Bituthene

System 4000 Membrane and Conditioner

only in dry weather and when air and surface temperatures are

25°F (-4°C) or above.

• Apply Bituthene

Primer B2 or Bituthene

Primer B2 LVC in

dry weather above 25°F (-4°C). (See separate product informa-

tion sheet.)

Conditioning

Bituthene

System 4000 Surface Conditioner is ready to use and

can be applied by spray or roller. For best results, use a pump-

type air sprayer with fan tip nozzle, like the Bituthene

System

4000 Surface Conditioner Sprayer, to apply the surface condi-

tioner.

Apply Bituthene

System 4000 Surface Conditioner to clean, dry,

frost-free surfaces at a coverage rate of 300 ft

/gal (7.4 m

/L).

Coverage should be uniform. Surface conditioner should not be

applied so heavily that it puddles or runs. Do not apply condi-

tioner to Bituthene

membrane.

Allow Bituthene

System 4000 Surface Conditioner to dry one

hour or until substrate returns to its original color. At low temper-

atures or in high humidity conditions, dry time may be longer.

Bituthene

System 4000 Surface Conditioner is clear when dry

and may be slightly tacky. In general, conditioning should be

limited to what can be covered within 24 hours. In situations

where long dry times may prevail, substrates may be conditioned

in advance. Substrates should be reconditioned if signicant dirt

or dust accumulates.
