BITUTHENE® Liquid Membrane
Two component, elastomeric, liquid applied detailing compound for use with GCP waterproofing membranes
Bituthene® Liquid Membrane is a two component, elastomeric, cold applied, trowel grade material designed for a variety of uses with the GCP waterproofing systems. The VOC (Volatile Organic Compound) content is 10 g/L. Architectural and industrial maintenance regulations limit the VOC content in products classified as architectural coatings. Refer to Technical Letters for the most current list of allowable limits.
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.
- Liquid applied
- Tough, rubber-like
- Chemically cured
- Cold applied
- System compatible
|BITUTHENE® LIQUID MEMBRANE PROPERTY||PART A VALUE||PART B VALUE|
|Unit size||1.5 gal (5.7 L)||4 gal (15.1 L)|
|Net weight per unit||12.4 lbs (5.6 kg)||33 lbs (15 kg)|
|Units per pallet||100||24|
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. Store in a dry place above 40°F.
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 ensure 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 insuffcient 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 3⁄16 in. (2.3 mm) unless otherwise noted on details. 32 In fillet applications, the face of the fillet should be a minimum of ¾ 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.
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 f2 (1.6 m2). As a fillet and reinforcement, 1 gal (3.8 L) will cover approximately 14 linear feet (4.3 m).
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.
