Q&A

Maintenance Tips

• Inspect seals every 6–12 months: Check around windows, doors, and exterior joints for cracks, gaps, or edge lifting after seasonal weather changes.
• Clean gently: Use mild soap and water to remove dirt and dust—avoid solvents or abrasive cleaners that can weaken the silicone bond.
• Ensure proper curing: Keep sealed areas dry for at least 24 hours after application for full waterproof and weatherproof performance.
• Watch UV and weather exposure: Even though it is UV- and weather-resistant, periodically check outdoor beads for long-term wear or separation.
• Do not paint over it: This is 100% silicone and non-paintable, so choose the correct color (clear) during installation.
• Remove failed caulk completely: Do not layer over old or cracked silicone—fully remove and reapply for a durable seal.
• Maintain stable joints: Prevent movement in window/door frames to reduce stress that can cause tearing or detachment.
• Avoid standing water: Keep joints from prolonged water pooling to extend lifespan and mold resistance.
