Description
Waterproofing coating applied with a brush or a notched trowel and composed of elastomeric bitumen, mineral fillers and solvents.
UNITS PER SKID: 36
Material Use:
SOPRALASTIC 123 is a black, solvent-based elastomeric bitumen waterproofing coating designed to revitalize and extend the service life of existing roofs. It is suitable for use on both asphalt and metal roofing surfaces. The product provides a protective waterproofing layer but must be covered with a protective finish to ensure durability and UV resistance.
System Components:
SOPRALASTIC 123 is typically used in conjunction with the following materials to form a complete waterproofing system:
- Primer: ELASTOCOL 500 is recommended when applying SOPRALASTIC 123 over old, dry surfaces. It should be applied at a rate of approximately 0.25 L/m².
- Reinforcement Fabric: For crack repairs, a reinforcement fabric strip is embedded into a first layer of SOPRALASTIC 123 and then covered with additional material.
- Protective Top Coat: SOPRALASTIC 124 ALU is used as a reflective and protective aluminum coating over SOPRALASTIC 123, applied at a rate of 0.2 to 0.3 L/m². Alternatively, small gravel may be used as a protective layer.
Applications:
SOPRALASTIC 123 is intended for use in roof maintenance and repair applications, particularly for:
- Revitalizing aged asphalt roofs
- Waterproofing metal roof surfaces
- Sealing cracks and blisters in existing roofing membranes
Application Details:
- Surface Preparation: The substrate must be clean and dry. Blisters should be cut open and repaired prior to application.
- Application Method: SOPRALASTIC 123 is applied using a brush or squeegee at a rate of 0.5 L/m².
- Crack Repair: Apply a base layer of SOPRALASTIC 123, embed a reinforcement fabric strip, and cover with more SOPRALASTIC 123.
- Top Protection: Must be protected with SOPRALASTIC 124 ALU or small gravel to prevent UV degradation.
Special Notes:
- UV Resistance: SOPRALASTIC 123 is not UV stable and must be protected with a UV-resistant top coat or gravel.
- Drying Time: Approximately 24 hours, depending on ambient temperature and application thickness.
- Temperature & Humidity Limits: Not explicitly stated, but as a solvent-based product, application should be done in dry conditions with good ventilation. Avoid application near open flames or in high humidity.
- Pot Life: Not applicable due to solvent-based nature; remains usable as long as it is kept sealed and stored properly.
- Curing Time: Initial drying in 24 hours; full cure time not specified but dependent on environmental conditions.
- Coverage:
- SOPRALASTIC 123: 0.5 L/m² (approx. 40 ft² per gallon)
- ELASTOCOL 500 Primer: 0.25 L/m² (approx. 80 ft² per gallon)
- SOPRALASTIC 124 ALU: 0.2–0.3 L/m² (approx. 65–100 ft² per gallon)
- Thickness: Not specified in mils, but application rate suggests a moderate film build. Ensure even coverage to avoid thin spots.
- Storage: Store in original sealed containers for up to 36 months. Keep away from heat, sunlight, and ignition sources.
This system is ideal for roof restoration projects where a cost-effective, solvent-based bituminous waterproofing solution is required. Proper surface preparation and protective top coating are essential for long-term performance.
