Tackle leaks, drafts, and gaps with a clear, professional-grade silicone that seals out water, air, and moisture—and stays looking clean. This 10 oz cartridge lays a smooth, durable bead that’s water-ready in just 30 minutes, helping you finish projects faster without compromising strength.

Use it anywhere a long-lasting waterproof seal matters: around tubs and showers, sinks and backsplashes, windows and doors, plumbing penetrations, gutters, and even general auto and marine applications. The permanently flexible seal won’t yellow, shrink, or crack, so it can handle real-world movement and weather year after year. It meets ASTM C-920 Movement Class 35 for dependable performance.

Crafted from 100% silicone, this sealant is formulated for clarity and longevity. It’s mold- and mildew-resistant and designed for all-weather use. For best results, apply to clean, dry surfaces above 40°F. Note: not paintable; not for use on wet, damp, frozen, or contaminated surfaces; not for underwater applications or aquariums; and not recommended on brick, masonry, cementitious materials, or corrosion‑sensitive metals like brass and galvanized steel.

Proudly made in the USA, this sealant gives DIYers and pros alike the confidence of American-made quality and consistency—reliability you can trust when safeguarding the spaces that matter most.
