Q&A

Maintenance Tips

• Inspect twice yearly: Check window, door, and siding joints for cracks, gaps, or edge lifting after seasonal weather changes.
• Clean gently: Use mild soap and water only—avoid solvents or abrasive cleaners that can weaken silicone adhesion.
• Ensure full cure time: Keep sealed joints dry for at least 24 hours for maximum waterproof and weatherproof performance.
• Watch UV/weather exposure: Although UV-resistant, periodically check exterior beads for long-term wear in sun and rain.
• Do not paint over it: This is a 100% silicone sealant and non-paintable, so color (clear) is permanent at application.
• Remove failed caulk fully: Never patch over old silicone—remove completely and reapply for a durable, continuous seal.
• Maintain stable joints: Reduce movement stress in frames and siding to prevent tearing or separation over time.
• Prevent standing water: Limit prolonged water pooling on sealed areas to extend lifespan and mold resistance
