OSI Quad Max Window & Door Sealant, Clear, 9 Oz.

Introducing Quad Max Clear Sealant, a crystal‑clear 9‑ounce formula crafted for windows, doors, and siding projects. Its cutting‑edge polymer blend provides exceptional adhesion on interior and exterior substrates, even when moisture or low temperatures are present. The low viscosity ensures a smooth gun application, while the fast cure minimizes downtime. Engineered for extreme temperature swings, it stays flexible in winter and durable in summer, delivering a seamless, invisible finish that resists UV degradation for long‑term protection.

Why choose this sealant? It creates a watertight barrier that blocks drafts and water infiltration, extending the lifespan of your frames. The low‑odor, solvent‑free composition guarantees safe indoor use without the mess of traditional caulks. Additionally, its non‑solvent base prevents corrosion on metal components, preserving structural integrity over time.

• Superior Wet‑Surface Bonding: Adheres instantly to damp or chilled surfaces, eliminating the need for extensive drying time; the formula penetrates micro‑pores to form a bond that endures repeated moisture cycles.
• UV‑Stabilized Formula: Resists sun‑induced cracking and yellowing, maintaining clarity for years; built‑in UV inhibitors lock in color stability so the sealant never turns amber.
• No Shrinkage or Blistering: Stays flexible after curing, providing a crack‑free seal that won’t bubble; even after extreme temperature fluctuations the seal remains intact without forming gaps.
• Clear, Paint‑Friendly Appearance: Remains invisible and can be painted over once cured for a seamless finish; after curing, paint adheres perfectly, allowing you to match any décor.
• Versatile Application Range: Suitable for residential and commercial projects on windows, doors, siding, and trim; works on wood, aluminum, PVC, and fiber‑cement substrates.

Experience lasting protection: With its robust weather‑proof performance and crystal‑clear look, this sealant ensures your openings stay sealed against the elements while preserving aesthetic appeal. Trust Quad Max Clear to deliver a professional‑grade seal that stands up to harsh climates, making every installation look finished and secure.
