Description
Non-woven, white needle-punched polyester fabric used as fabric reinforcement in ALSAN RS systems to improve tear strength, puncture resistance, flexural fatigue and crack bridging capabilities while maintaining membrane uniformity.
UNITS PER SKID:
Depending on the width:
4" - 250
10.3" - 100
13.8" - 60
21" - 75
41" - 25
Material Use:
ALSAN RS FLEECE is a non-woven, white needle-punched polyester fabric designed as a reinforcement layer in ALSAN RS two-component cold liquid-applied membrane systems. It is used to enhance the mechanical properties of the membrane system, including tear strength, puncture resistance, flexural fatigue resistance, and crack-bridging capabilities, while ensuring uniform membrane thickness and performance.
System Components:
ALSAN RS FLEECE is used in conjunction with ALSAN RS liquid resins, which are catalyzed with ALSAN RS CATALYST. The fleece is embedded between layers of the liquid resin to form a composite waterproofing or surfacing membrane. It is important to note that ALSAN RS FLEECE is not compatible with ALSAN FLASHING or COLPHENE LM BARR, which require SOPREMA POLYFLEECE instead.
Applications:
ALSAN RS FLEECE is suitable for use in a variety of waterproofing and surfacing applications, including:
- Balconies and plaza decks
- Roofs
- Fountains and ponds
Application Details:
The application process involves first preparing the substrate and applying a liberal coat of catalyzed ALSAN RS resin using a roller. The fleece is then rolled out onto the wet resin with the smooth side facing up. It should be allowed to saturate from the bottom up. A medium nap roller wet with resin is used to press the fleece into the resin, removing air bubbles and wrinkles. Additional resin is applied on top until the fleece is fully saturated and no white or dull areas remain. The final surface should be smooth and uniform. Overlaps must be maintained as follows: 5 cm (2 in) at field and flashing side laps, 10 cm (4 in) at end laps, and 10 cm (4 in) at wall bases and penetrations. A minimum of 5% additional material should be accounted for as waste.
Special Notes:
- ALSAN RS FLEECE is available in various widths (ranging from 10 cm to 104 cm) and comes in 50 m (165 ft) long rolls.
- The fleece has a nominal thickness of 0.65 mm (25 mils) and a weight of 110 g/m² (0.36 oz/ft²).
- It offers high elongation (70% MD, 80% CD) and tensile strength (53 N MD, 59 N CD).
- Store the rolls flat in a cool, dry place to prevent deformation or creasing.
- ALSAN RS FLEECE is an accessory product and must be used as part of the ALSAN RS liquid membrane system.
- Not UV stable on its own; UV resistance depends on the topcoat resin used in the system.
- ALSAN RS FLEECE is a reinforcement layer and does not have a standalone coverage rate in Gal/ft², but fleece coverage is based on roll dimensions and overlaps.
This material is a critical component in the ALSAN RS system and must be used with compatible ALSAN RS resins and catalyst for optimal performance in waterproofing and surfacing applications.
