Only apply BITUTHENE Liquid Membrane (E) in dry weather and when air temperatures are between 5°C and 40°C.
Surfaces must be structurally sound and free of voids, spalled areas, loose aggregate and sharp protrusions. Repair concrete defects such as spalled or poorly consolidated areas and remove sharp protrusions. Remove contaminants such as grease, oil and wax from exposed surfaces. Remove dust, dirt, loose stone and debris. Concrete must be properly cured (minimum 7-days for normal structural concrete and 14-days for lightweight structural concrete) and shall be dry to <5% moisture content. Substrate temperature shall be between 5°C and 45°C. PREPRUFE and BITUTHENE membrane surfaces shall be clean, dry and undamaged.
BITUTHENE Liquid Membrane (E) pack is supplied in a single can containing Part A base with the Part B reactor located separately under the can lid. Using a slow speed mixer, pre-mix part A then, add Part B (clear) to Part A (black). Mix the two parts for approximately 1 minute at 100 rpm. Mix for a further 2-3 minutes at 200-300 rpm until uniform blending is achieved. Scrape the sides and bottom of the container during mixing to ensure thorough blending. At ambient temperatures below +10°C, store overnight at +20°C to improve blending and workability. Clean tools and equipment before BITUTHENE LM (E) liquid membrane has cured.
When used as a stand alone system, BITUTHENE Liquid Membrane (E) are mixed and applied in accordance with manufacturer’s instructions with a trowel or float, solid barrel gun or hand held squeegee to achieve a minimum thickness of 1.5mm. Apply to a minimum thickness of 2.5mm when used as a detailing aid with BITUTHENE or PREPRUFE membranes.
Once mixed BITUTHENE Liquid Membrane (E) should be applied within 30mins to one hour. Material thickens quicker as the ambient temperature increases, which thickened material must be discarded. BITUTHENE Liquid Membrane (E) shall be allowed to cure for 24 hours before being overlapped by BITUTHENE or PREPRUFE Membranes.
A minimum overlap of the BITUTHENE sheet membrane of 50 mm shall be provided and where applicable between 50 mm and 75 mm onto PREPRUFE sheet membranes.
BITUTHENE Liquid Membrane (E) is designed to adhere to clean, dry concrete and metal substrates.
BITUTHENE Liquid Membrane (E) application should be sequenced as detailed in any drawings or installation instructions for BITUTHENE and PREPRUFE waterproofing membranes.
