- Tough, rubber-likeflexible and damage resistant
- Chemically curedunaffected by in-service temperature variations
- Cold appliedno flame hazard
- System compatibleformulated for use with Grace waterproofing membrane systems
Use
Bituthene Liquid Membrane is ideally suited for
the following uses:
- Fillet material at inside corners
- Reinforcement material at inside corners
- Flashing material around drains, protrusions, curbs and parapets
- Sealing material at terminations
- Repair material for defects on concrete surfaces
- Flashing material at corners
The two parts of Bituthene Liquid Membrane are
mixed on site and troweled on to provide a simple
and quick waterproofing detailing aid in conjunction
with Bituthene, Preprufe and Procor
systems.
Compatibility
Bituthene Liquid Membrane is completely
compatible with Bituthene, Preprufe and Procor,
and with existing asphalt or coal tar-based waterproofing
materials. It is also compatible with
cured silicone and polyurethane sealants. It is not
compatible with creosote, pentachlorophenol,
linseed oil or polysulfide-based sealants.
Application Procedures:
Safety, Storage and Handling Information
Bituthene products must be handled properly.
Vapors from solvent-based primers and mastic are
harmful and flammable. 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
All surfaces must be dry and free from dirt,
grease, oil, dust or other contaminants. Bituthene
Liquid Membrane may be applied at temperatures
of 25°F (-4°C) or above. Below 40°F (5°C), store
in a warm place before application.
Mixing
Add the entire contents of the Part B container to
Part A and mix for 3 to 5 minutes until uniform.
Part A is black and Part B is clear. Take care to
scrape material from the side and bottom of the
containers to assure thorough mixing. A low speed
(150 rpm) mechanical mixer with flat paddle
blades is required. Do not apply any material if
streaks can be seen due to insufficient mixing.Once mixed, Bituthene Liquid Membrane must be
applied by trowel within 1.5 hours. More time is
available at lower temperatures. At high temperatures,
thickening and curing will be faster. Material
that has thickened must be discarded. The material
will cure to a very flexible rubber-like material.
Bituthene Liquid Membrane must be applied at a
minimum thickness of 3/32 in. (2.3 mm) unless
otherwise noted on details. In fillet applications,
the face of the fillet should be a minimum of 3/4 in.
(20 mm). In corner flashing application details, it
should extend 6 in. (150 mm) in each direction
from the corner. Bituthene Liquid Membrane will
adhere to primed or unprimed concrete.
Bituthene Liquid Membrane should be allowed to
cure at least 24 hours before flood testing.
Coverage
As a fillet material, 1 gal (3.8 L) will cover
approximately 100 linear feet (30 m). As a flashing
material, 1 gal (3.8 L) will cover approximately
17 ft2 (1.6 m2). As a fillet and reinforcement,
1 gal (3.8 L) will cover approximately 14 linear
feet (4.3 m).
Cleaning
Clean tools and equipment with mineral spirits
before Bituthene Liquid Membrane has cured.
Mineral spirits is a combustible liquid and should
be used only in accordance with the manufacturer’s
safety recommendations. Do not use
solvents to clean hands or skin.
