Description
Waterproofing coating applied with a brush or a roller composed of elastomeric bitumen, mineral fillers and solvents.
UNITS PER SKID: 36
Material Use:
SOPRALASTIC 124 ALU is a reflective, elastomeric bitumen-based waterproofing and protective coating designed primarily for use on metal surfaces and bituminous membranes. It serves as a corrosion inhibitor for metal substrates such as sidings, corrugated steel sheets, fibre cement tanks, gutters, and ducts. Additionally, it provides UV protection for sanded bituminous membranes and previously applied SOPRALASTIC 123 coatings. Its aluminium pigmentation offers excellent reflectivity, contributing to reduced interior building temperatures and enhanced UV resistance.
System Components:
SOPRALASTIC 124 ALU is typically used as a standalone topcoat or in conjunction with SOPRALASTIC 123, which acts as a base waterproofing layer. When used as a system, SOPRALASTIC 123 provides the primary waterproofing function, while SOPRALASTIC 124 ALU serves as the UV-resistant and reflective final coat. No primer is specifically required for clean metal surfaces, but proper surface preparation is essential.
Applications:
This material is suitable for use on:
- Metal sidings and corrugated steel sheets
- Fibre cement tanks
- Gutters and ducts
- Sanded bituminous membranes
- As a topcoat over SOPRALASTIC 123 for UV protection
Application Details:
- Surface Preparation: Surfaces must be clean, dry, and free of loose particles. Corroded metal should be cleaned thoroughly before application.
- Application Method: Apply using a brush, roller, or airless sprayer.
- Coverage Rate:
- Clean metal: 0.2 to 0.3 L/m² (approx. 80–120 ft² per gallon)
- Corroded metal or sanded membranes: up to 0.5 L/m² (approx. 50 ft² per gallon)
- Drying Time: Approximately 24 hours, depending on ambient temperature and application thickness.
- Number of Coats: One coat is typically sufficient; if a second coat is needed, ensure the first coat is completely dry before reapplication.
Special Notes:
- UV Resistance: Excellent; the aluminium pigmentation provides long-term UV protection.
- Temperature & Weather Limitations: Do not apply during rain or in high humidity. Application should be done in dry conditions with adequate ventilation.
- Flammability: Highly flammable. Keep away from open flames and ignition sources during application and until the solvent has fully evaporated.
- Storage: Store in original sealed containers in a cool, ventilated area. Shelf life is up to 36 months.
- Cleaning Tools: Use petroleum-based solvents such as mineral spirits, varsol, or xylene.
- Health & Safety: Harmful if inhaled, ingested, or in contact with skin. Use appropriate PPE and ensure proper ventilation, especially in enclosed spaces.
SOPRALASTIC 124 ALU is best used as a reflective and protective topcoat in waterproofing systems, particularly when UV resistance and thermal reflectivity are required. It pairs effectively with SOPRALASTIC 123 for a complete waterproofing and UV-protective system.
