Key sealant

Key sealant is a versatile, high‑performance sealant designed to create durable, flexible seals across a wide range of projects. This silicone‑based formula bonds to metal, glass, ceramic, wood, and plastic, delivering a reliable barrier against drafts, moisture, and dust. Whether you’re weatherproofing a drafty doorway, sealing around plumbing fixtures, or tidying up small gaps in cabinets and appliances, Key sealant provides a seamless, long‑lasting finish you can trust.

Why Key sealant stands out

• Flexible and durable: maintains an elastic seal that moves with the substrate without cracking or pulling away.
• Weatherproof and waterproof: creates a robust barrier ideal for indoor and outdoor use, helping to protect against rain, humidity, and temperature changes.
• Strong adhesion to common materials: sticks well to metal, glass, ceramic, wood, and many plastics with proper surface prep.
• Easy to work with: smooths easily with a damp finger or tool, allowing clean joints and neat finishes.
• Convenient cleanup: uncured material cleans up with soap and water, making cleanup quick and simple.

Ideal use cases

• Weatherproofing doors and window frames to reduce drafts and energy loss.
• Sealing around sinks, tubs, and bathroom fixtures to prevent water intrusion and mold growth.
• Gasketing small gaps in cabinetry, countertops, and backsplashes for a clean, finished look.
• Sealing electrical outlets, appliance housings, and light fixtures where moisture resistance is beneficial.
• General repair and maintenance projects where a flexible, resilient seal is required.

How to apply

1. Prepare the surface: clean, dry, and free of old sealant, grease, or dust.
2. Cut the nozzle to your desired bead size and load into a caulking gun.
3. Apply a steady, continuous bead along the gap or joint.
4. Tool and smooth the seal with a damp finger or a suitable shaping tool for a clean finish.
5. Allow the sealant to cure in a well‑ventilated area. Cure time varies with temperature, humidity, and gap size.

Performance you can rely on

Key sealant is designed for practical, real‑world use. It provides a dependable seal that remains flexible over time, tolerates substrate movement, and resists the stresses of daily life. It’s well suited for DIY enthusiasts, homeowners, and professionals who need a trustworthy solution that delivers consistent results—without requiring specialized tools or complex workflows.
