- Compatible in direct contact with the silver coating on mirrors and PVB-laminated glass.
- No edge contamination, staining or bleeding on porous materials, such as concrete, natural stone and untreated wood.
- Sandable and grindable once fully cured; paintable immediately after skin formation.
- Non-corrosive to metals.
- Absorbs acoustic and mechanical vibrations well.
- Usable wet-on-wet, repair with the same material.

Application conditions
- Application temperature (ambient and surface) between +5°C and +40°C.
- On clean, uncontaminated, compatible, stable, grease-free and dust-free surfaces.
- Ensure proper joint dimensions, for proper absorption of any movements.
- Use a suitable brush to remove any loose particles from the surface.
- Degrease the surface properly using Seal-it® 510 CLEANER.
- Seal-it® 352 SUPER-PRO has a broad bonding spectrum, but highly porous surfaces should be pre-treated with Seal-it® 520 PRIMER and non-porous surfaces with minimal bonding should be treated with Seal-it® 525 Clean & Bond.
- For adhesive applications, apply material vertically (ventilation) in beads spaces between a minimum of 10 cm and a maximum of 20cm. Do not apply in dabs! It is recommended to use double-sided adhesive SEAL-IT® 560 PANELTAPE to support adhesion during the curing process and to achieve the correct adhesive thickness.
- Use Seal-it® 550 FINISH to apply a smooth and tight finish, before skin formation.
