Description
Water-based, single-component, liquid air/vapour barrier made of synthetic rubbers used on walls.
ITEMS PER SKID: 36
Material Use:
SOPRASEAL LM 200 S is a single-component, water-based, synthetic rubber liquid membrane designed for use as an air and vapour barrier. It is primarily used in wall applications to provide a continuous, monolithic barrier that prevents air leakage and moisture ingress. The product is spray-applied and forms a seamless membrane upon curing.
System Components:
SOPRASEAL LM 200 S is used in conjunction with SOPRASEAL SEALANT, which is applied around penetrations, joints, and other critical areas to ensure a complete and secure seal. Together, these products form a comprehensive air/vapour barrier system. No primer is specifically required for SOPRASEAL LM 200 S, but the substrate must be properly prepared to ensure adhesion.
Applications:
This product is suitable for use on a variety of building substrates including masonry, concrete, wood, and gypsum. It is ideal for commercial and residential wall assemblies where a high-performance air and vapour barrier is required. SOPRASEAL LM 200 S is particularly effective in new construction and retrofit projects where spray application is feasible.
Application Details:
- Application Method: Spray-applied using a spray tip 543 with pump pressure up to 3000 psi (recommended starting pressure: 1100 psi).
- Minimum Application Temperature: 2 °C (36 °F)
- UV Exposure Limit: Maximum 2 months before covering
- Dry to Touch (Tack-Free Time): 1 to 3 hours
- Wet Film Thickness: 2.0 mm (80 mils)
- Dry Film Thickness: 1.0 mm (40 mils)
- Coverage Rate: Approximately 10 m² (100 ft²) per 19 L pail when used as a vapour barrier
- Pot Life: Not applicable (single-component, ready-to-use)
- Curing Time: Tack-free in 1–3 hours; full cure time not specified but dependent on environmental conditions
- Cleaning: Uncured material can be cleaned with soap and water; cured material requires solvents or mechanical removal
Special Notes:
- SOPRASEAL LM 200 S is not UV stable and must be covered within 2 months of application.
- A wet film gauge must be used during application to ensure the correct thickness is achieved.
- The product exhibits excellent elongation (240%) and air barrier performance, with air permeability of < 0.001 L/s•m² and water vapour permeance of 12 ng/Pa•s•m² (0.2 perm) under ASTM E96 Procedure A.
- Nail sealability is confirmed per ASTM D1970, making it suitable for use in assemblies where mechanical fasteners are used.
- Store in original, unopened containers for up to 24 months. Protect from freezing.
This product is best suited for use as part of a wall air/vapour barrier system in combination with SOPRASEAL SEALANT, and should be applied under appropriate environmental conditions to ensure optimal performance.
