Description
Water-based, single-component, liquid air/vapour barrier made of synthetic rubbers used on walls.
UNITS PER SKID: 36
Material Use:
SOPRASEAL LM 200 T is a water-based, single-component, rubberized liquid membrane designed for use as an air and vapour barrier or as an insulation adhesive. It is suitable for application on a variety of building materials including masonry, concrete, wood, and gypsum board. The product is particularly effective in conjunction with rigid or semi-rigid thermal insulation boards, including polystyrene. It forms a flexible, durable film that resists air leakage and moisture vapour transmission, while also bridging minor substrate cracks.
System Components:
SOPRASEAL LM 200 T is used in combination with SOPRASEAL SEALANT, which is applied around details and critical areas to ensure a continuous and sealed air/vapour barrier system. This combination forms a complete system for air and vapour control in wall assemblies.
Applications:
This product is intended for use in wall assemblies where air and vapour control is required. It is ideal for commercial and residential construction projects involving concrete, masonry, wood, or gypsum substrates. SOPRASEAL LM 200 T is not designed for permanent exposure and must be covered by cladding or other protective layers.
Application Details:
SOPRASEAL LM 200 T should be applied to clean, sound substrates that are free of loose materials, grease, and contaminants. It can be applied using a trowel or brush. The minimum application temperature is 2°C (35.6°F). The product can be applied over damp surfaces, which adds flexibility during installation in variable site conditions. The recommended wet film thickness is 2.3 mm (90 mil), which dries to approximately 1.15 mm (45 mil). Each 19 L (5 gal) container covers approximately 10 m² (100 ft²), equating to a coverage rate of 20 ft² per gallon.
Special Notes:
- Pot Life: Not applicable as this is a single-component product.
- Drying Time: Dry to touch in 1 to 3 hours at 25°C (77°F); 90% cure in 7 to 14 days; full cure in 30 days.
- Temperature Range for Application: Minimum 2°C (35.6°F).
- Humidity Considerations: Curing time is affected by relative humidity, temperature, and air movement.
- UV Resistance: SOPRASEAL LM 200 T is not UV stable and must be protected from permanent exposure.
- Thickness Limits: Wet film thickness of 2.3 mm (90 mil); dries to 1.15 mm (45 mil).
- Coverage: Approximately 20 ft² per gallon at recommended thickness.
- Storage: Shelf life of up to 2 years in original sealed containers. Must be kept from freezing.
- Cleaning: Uncured material can be cleaned with soap and water; cured material requires solvents such as mineral spirits, Varsol, or Xylene, or mechanical removal.
This product is best suited for use in air and vapour barrier systems in wall assemblies and should be used in conjunction with SOPRASEAL SEALANT for optimal performance. It is not intended for roofing or exposed waterproofing applications.
