Description
Colorless finishing resin made from polymethyl methacrylate (PMMA) used as a protective coating when decorative accessories as ALSAN FLOOR FLAKES or ALSAN FLOOR QUARTZ are applied.
Material Use:
ALSAN RS 281 CLEAR FINISH is a clear, liquid-applied, polymethyl methacrylate (PMMA)-based finish resin designed to serve as a sealer or topcoat in decorative and waterproofing systems. It is primarily used as a final clear coat over surfaces treated with coloured quartz aggregate or vinyl paint chips, providing a durable, UV-resistant, and aesthetically pleasing finish. This product is ideal for use in exposed areas such as balconies, plaza decks, fountains, ponds, and roofs.
System Components:
ALSAN RS 281 CLEAR FINISH is used in conjunction with ALSAN RS CATALYST POWDER, which initiates the curing process. It is typically applied as the final layer in a PMMA-based waterproofing or surfacing system. The system may include a base coat such as ALSAN RS 230 FIELD or ALSAN RS 260 LO FIELD, followed by decorative aggregates (e.g., silica sand or paint chips), and sealed with ALSAN RS 281 CLEAR FINISH. The catalyst dosage varies depending on ambient temperature, ranging from 2% to 6% of the resin weight.
Applications:
This material is suitable for use in a variety of horizontal and vertical applications where a clear, protective, and UV-resistant finish is required. Common applications include:
- Balconies and plaza decks
- Fountains and ponds
- Exposed roof areas
- Decorative surfacing systems using quartz or vinyl chips
Application Details:
ALSAN RS 281 CLEAR FINISH must be mixed thoroughly with ALSAN RS CATALYST POWDER before application. The catalyst amount is temperature-dependent:
- 0 °C to 10 °C: 6% catalyst
- 10 °C to 20 °C: 4% catalyst
- 20 °C to 35 °C: 2% catalyst
Mix the resin and catalyst for 2–3 minutes using a slow-speed mixer (200–400 rpm). Apply the mixed resin using a roller, brush, or flat blade squeegee to a clean, dry, and properly prepared substrate. The product should be applied evenly to achieve the desired finish.
Coverage and Thickness:
Coverage rates vary depending on the type of finish:
- Smooth finish: 18.5 m² (200 ft²) per 10 kg container at 0.58 mm (23 mils) total thickness
- Aggregate #0 (32 mesh): 15 m² (166 ft²) per 10 kg container at 0.66 mm (26 mils)
- Aggregate #1 (24 mesh): 13 m² (142 ft²) per 10 kg container at 0.76 mm (30 mils)
Special Notes:
- Pot Life: 10–15 minutes after mixing, depending on ambient temperature
- Rainproof Time: 30–45 minutes
- Set Time / Walkable / Next Layer: 45–60 minutes
- Full Cure Time: Approximately 3 hours
- Application Temperature Ranges:
- Ambient: 0 °C to 35 °C (32 °F to 95 °F)
- Substrate: 0 °C to 50 °C (32 °F to 122 °F)
- Resin: 3 °C to 30 °C (37 °F to 86 °F)
- UV Stability: ALSAN RS 281 CLEAR FINISH is UV-resistant, making it suitable for exterior applications.
- Storage: Store indoors at 0 °C to 25 °C (32 °F to 77 °F), away from heat and direct sunlight. Shelf life is approximately 12 months in original sealed containers.
- Limitations: Do not apply in high humidity or when rain is expected within the curing window. Ensure proper ventilation during application.
ALSAN RS 281 CLEAR FINISH is a high-performance, fast-curing, and UV-resistant clear coat that enhances the durability and appearance of PMMA-based surfacing systems. It is best used as part of a complete ALSAN RS system for waterproofing and decorative surfacing.
