Description
Polyether-based, single-component, water-reactive elastomeric sealing mastic and adhesive used to bond SOPRAMASTIC BLOCKS between them and to horizontal and vertical surfaces in the SOPRAMASTIC BLOCK system for details and penetrations.
UNITS PER SKID: 1080
Material Use:
SOPRAMASTIC SP2 is a single-component, polyether-based, moisture-cure elastomeric sealing mastic and adhesive. It is primarily used for waterproofing around roofing penetrations and as an adhesive for bonding precast blocks and roofing accessories. The product is odourless, has low VOC content, and is designed for use in roofing systems, particularly in conjunction with SBS-modified bitumen membranes.
System Components:
SOPRAMASTIC SP2 is used as part of a waterproofing system that includes:
- SOPRAMASTIC BLOCK precast blocks (used to form a protective structure around penetrations)
- SOPRAMASTIC PF sealing mastic (used to fill horizontal surfaces within the block configuration)
- SOPRAGLASS 100 or other oxidized bitumen membranes (as the base roofing membrane)
Applications:
This product is ideal for sealing and bonding around complex roof penetrations such as pipes and mechanical supports. It is compatible with SBS-modified bitumen membranes (granular or sanded), organic felt, and oxidized bitumen membranes. SOPRAMASTIC SP2 can be applied to both horizontal and vertical surfaces and is suitable for use in new construction or repair applications.
Application Details:
- Surface Preparation: All surfaces must be clean, dry, and free of dust, oil, rust, or other contaminants. Metal and PVC surfaces should be cleaned with non-greasy solvents like acetone or MEK.
- Application Method: Apply using a standard cartridge extruder. A 6 mm (1/4 in) bead is applied under and around the SOPRAMASTIC BLOCK precast blocks. The sealant should also be applied around the base of penetrations and at least 25 mm (1 in) above the block height. Joints and perimeters are sealed with SOPRAMASTIC SP2 and bonded to the membrane using a trowel.
- Horizontal Surfaces: Fill with SOPRAMASTIC PF.
- Vertical Surfaces: Fill with SOPRAMASTIC SP2.
Special Notes:

- Coverage: One 300 ml (10.1 oz) cartridge covers approximately 4.5 linear meters (15 linear feet)
- Viscosity: 1,200,000 cP at 25 °C (77 °F)
- Solids Content: 100%
- Tensile Strength: 2.3 MPa (330 psi)
- Elongation at Break: 290%
- Hardness: Shore A 45
- Shrinkage: None visible after 14 days
- Cleaning: Tools can be cleaned with mineral spirits, Varsol, or xylene
SOPRAMASTIC SP2 is a critical component in SOPREMA’s roofing detail waterproofing system, offering strong adhesion, flexibility, and ease of application in a variety of environmental conditions. It is especially effective when used in combination with SOPRAMASTIC BLOCK and SOPRAMASTIC PF for complete sealing of roof penetrations.
