Description
Two-component liquid membrane composed of polymethacrylate (PMA) designed for waterproofing of flashings on new surfaces or surfaces under repair, whether for indoor or outdoor applications.
ITEMS PER SKID: 60
Material Use:
ALSAN RS 260 LO FLASH is a high-performance, low-odor, rapid-setting polymethacrylate (PMA) liquid resin designed specifically for flashing applications in waterproofing systems. It is used to create a flexible, monolithic, and reinforced membrane that provides long-lasting protection in critical detailing areas. This material is ideal for use in roofing, balconies, plaza decks, fountains, and ponds where complex geometries or penetrations require a seamless waterproofing solution.
System Components:
ALSAN RS 260 LO FLASH is used in conjunction with the following components to form a complete waterproofing system:
- ALSAN RS CATALYST POWDER: Required for initiating the curing process of the resin.
- ALSAN RS FLEECE: A reinforcing fabric embedded into the resin to enhance membrane strength and flexibility.
- Primers: Depending on the substrate, either ALSAN RS 222 PRIMER or ALSAN RS 276 PRIMER must be used to ensure proper adhesion.
Applications:
This material is suitable for use in:
- Flashing details on roofs
- Waterproofing balconies and plaza decks
- Sealing and lining fountains and ponds
- Areas requiring rapid installation and return to service
- Environments where low odor is critical, such as occupied buildings
Application Details:
- Mixing: Mix the entire container of resin for 4 minutes using a slow-speed (200–400 rpm) mechanical agitator. Add the appropriate amount of ALSAN RS CATALYST POWDER based on ambient temperature (2–6% by weight), stir for 2–3 minutes, and apply immediately.
- Application Method: Apply using rollers, brushes, or notched squeegees. Embed ALSAN RS FLEECE into the wet resin and apply a second coat to fully saturate the fleece.
- Coverage: Coverage varies by substrate profile:
- Smooth (CSP 1): 4.1 m² (44 ft²) per 12.5 kg unit
- Typical (CSP 3–4): 3.7 m² (40 ft²)
- Granulated (CSP 5): 3.3 m² (35 ft²)
- Rough (CSP 6): 2.9 m² (31 ft²)
- Thickness: Total system thickness ranges from 2.5 mm (98 mils) to 3.6 mm (140 mils), depending on substrate roughness. Base coat thickness ranges from 1.6 mm (63 mils) to 2.7 mm (105 mils), and top coat from 0.9 mm (35 mils) to 1.0 mm (40 mils).
Special Notes:
- Pot Life: 10–15 minutes after catalyst addition, depending on temperature.
- Curing Time:
- Rainproof: 15–20 minutes
- Walkable / Next Layer: 1–2 hours (winter), 60–90 minutes (summer)
- Full Cure: 5 hours (winter), 4–7 hours (summer)
- Temperature Limits:
- Application (resin): 10 °C to 50 °C (50 °F to 122 °F)
- Ambient: 0 °C to 20 °C (winter), 10 °C to 35 °C (summer)
- Substrate: 0 °C to 20 °C (winter), 10 °C to 30 °C (summer)
- Humidity: Surfaces must be dry; avoid application in high humidity or wet conditions.
- UV Resistance: ALSAN RS 260 LO FLASH is UV stable and suitable for exposed applications.
- VOC Content: < 5 g/L, making it compliant with low-emission requirements.
- Storage: Store indoors at 0 °C to 25 °C (32 °F to 77 °F), away from heat and direct sunlight. Shelf life is 12 months in original container.
System Compatibility and Use Cases:
ALSAN RS 260 LO FLASH is part of the ALSAN RS PMA liquid-applied waterproofing system and must be used with ALSAN RS CATALYST POWDER and ALSAN RS FLEECE. It is compatible with ALSAN RS 222 and 276 primers depending on the substrate. This system is ideal for detailing and flashing in conjunction with ALSAN RS field membranes, providing a seamless transition between horizontal and vertical surfaces or around penetrations. It is especially useful in areas requiring fast installation and return to service, such as commercial roofs, balconies, and water features.
