Description
Polyether-based, single-component, water-reactive elastomeric sealing mastic used on horizontal surfaces in the SOPRAMASTIC BLOCK system for details and penetrations.
UNITS PER SKID: 48
QUANTITY PER PACKAGING: 4 PC
Material Use:
SOPRAMASTIC PF is a single-component, moisture-cure, polyether-based elastomeric sealing mastic designed for waterproofing applications on roofing systems. It is primarily used to seal around complex roof penetrations and to fill cavities within SOPRAMASTIC BLOCK precast blocks. This product is ideal for use in conjunction with SBS-modified bitumen membranes and other compatible roofing substrates.
System Components:
SOPRAMASTIC PF is part of a complete waterproofing system that includes:
- SOPRAMASTIC PF (sealing mastic)
- SOPRAMASTIC BLOCK (precast blocks for forming around penetrations)
- SOPRAMASTIC SP2 (sealant and adhesive used for bonding and sealing joints)
These components work together to create a watertight seal around roof penetrations and other vulnerable areas.
Applications:
SOPRAMASTIC PF is used in roofing applications, particularly for sealing around penetrations such as pipes and conduits. It is compatible with SBS-modified bitumen membranes (granular or sanded), organic felt, and oxidized bitumen membranes like SOPRAGLASS 100. It is suitable for use on horizontal surfaces and is applied within the SOPRAMASTIC BLOCK system to ensure complete waterproofing.
Application Details:
- Surface Preparation: All surfaces must be clean, dry, and free of dust, debris, oil, rust, or other contaminants. Metal and PVC surfaces should be cleaned with non-greasy solvents like acetone or MEK.
- Application Temperature: Minimum application temperature is 0 °C (32 °F). The product should not be applied if rain is expected within 4 hours.
- Service Temperature Range: -40 °C to 93 °C (-40 °F to 200 °F). However, the SOPRAMASTIC BLOCK system should not be exposed to temperatures above 60 °C (140 °F) for extended periods.
- Curing Time: Skin-over time is approximately 20 minutes. The product becomes waterproof once dry to the touch. Full cure time depends on ambient temperature and humidity.
- Pot Life: As a single-component moisture-cure product, SOPRAMASTIC PF does not have a traditional pot life but begins curing upon exposure to air.
- Thickness & Coverage: SOPRAMASTIC PF is applied as a liquid mastic to completely fill the cavity within the SOPRAMASTIC BLOCK system. Specific thickness in mils is not provided, but application should ensure complete fill and coverage. Coverage rate is not explicitly stated; however, the product is packaged in 2 L (0.5 US gallon) pouches.
- UV Resistance: Not explicitly stated; however, as it is used under precast blocks and in protected roofing details, direct UV exposure is likely minimal.
- Cleaning: Tools can be cleaned with mineral spirits, Varsol, or xylene.
Special Notes:
- SOPRAMASTIC PF is odourless and has a low VOC content (<15 g/L), making it suitable for use in sensitive environments.
- The product has 100% solids content and exhibits no visible shrinkage after 14 days.
- SOPRAMASTIC PF should be stored in its original container at temperatures above 0 °C (32 °F) and used within 12 months of manufacture.
- Avoid application in wet conditions or when rain is expected within four hours.
- This product is not intended for use as a standalone waterproofing membrane but as part of a detail-sealing system in conjunction with SOPRAMASTIC BLOCK and SOPRAMASTIC SP2.
This material is best suited for detailed waterproofing around roof penetrations and should be used as part of the SOPRAMASTIC BLOCK system for optimal performance.
