Experience a seal that moves with your home. OSI Quad Max Sumner Suede Elastomeric Caulk Sealant is a high-performance, paintable sealant designed for interior and exterior use. Made with elastomeric polymers, it remains permanently flexible to accommodate shifting surfaces without cracking or losing grip. The Sumner Suede shade blends seamlessly with gray tones for a clean, professional finish.
What makes it different
- Moisture resistant and mildew resistant, ideal for bathrooms, kitchens, and damp areas.
- Permanently flexible elastomeric formula that tolerates expansion and contraction from temperature changes and building movement.
- Paintable after cure, so you can match or customize to your décor or trim.
- Indoor and outdoor performance on a wide range of joint types and substrates (surface prep and cure conditions required).
- Cartridge packaging for easy dispensing with standard caulking guns; includes a 9.5 oz cartridge for larger projects.
- Not rated for high heat or fire resistance; best suited for typical living spaces, exterior trim, and interior gaps.
Where to use
Seal gaps around windows and doors, along baseboards and crown molding, in kitchens and bathrooms around sinks, tubs, and showers, and on exterior siding seams. The Sumner Suede color provides a neutral, modern look that hides minor imperfections while blending with common gray palettes.
Tips for best results

- Cut nozzle to desired bead size and apply with steady, even pressure.
- Tool the bead using a damp finger or caulk-finishing tool for a smooth, professional line.
