Customer Questions & Answers
-
Question:
What surfaces can I use Flex Seal spray on?
Answer: Flex Seal spray can be used on a variety of surfaces including metal, wood, rubber, plastic, and fiberglass. It creates a strong, flexible barrier that adheres to numerous materials making it perfect for both indoor and outdoor applications. For instance, you can use it to seal roof leaks, fix cracks in wood furniture, or even repair garden hoses. Just ensure the surface is clean and dry before application for the best results. -
Question:
How long does it take for Flex Seal to dry?
Answer: Flex Seal typically requires 24 to 48 hours to fully cure, depending on humidity and temperature conditions. While it may be touch dry within a few hours, allow it ample time to reach maximum strength and effectiveness. This is crucial for ensuring that your repairs are durable and long-lasting. Remember to plan your project accordingly, especially if it involves essential repairs like roofs or outdoor installations. -
Question:
Is Flex Seal spray safe to use indoors?
Answer: Yes, Flex Seal spray can be used indoors, but it's essential to ensure proper ventilation during application. The rubberized coating releases fumes while curing, so keep windows open or use fans to circulate air. This makes it suitable for various indoor projects, such as repairing leaking pipes or sealing around windows. Always follow safety precautions and wear a mask if you're sensitive to chemical odors. -
Question:
Can I paint over Flex Seal once it's dry?
Answer: Yes, you can paint over Flex Seal after it has completely cured. It's best to use oil-based or acrylic paints for adhesion and durability. This allows you to customize the appearance of your repairs without compromising their waterproof qualities. Use this in scenarios where aesthetics matter, such as when fixing outdoor furniture or visible roof areas. -
Question:
How do I apply Flex Seal spray for the best results?
Answer: For optimal application, shake the can thoroughly before use and spray from a distance of about 10-12 inches. Apply in thin, even layers to prevent drips and ensure complete coverage. This technique is effective for stopping leaks or sealing cracks, as it allows the product to penetrate into the material. Always overlap your strokes slightly for uniformity and let each coat dry before applying the next. -
Question:
Is Flex Seal suitable for all types of repairs?
Answer: Flex Seal is incredibly versatile and can be used for a wide range of repairs, including roofs, plumbing, automotive fixes, and even craft projects. However, it may not be ideal for extreme temperature conditions or areas subject to heavy abrasion. Consider using it for minor leaks or cracks in less demanding environments, such as indoor repairs or outdoor furniture. -
Question:
How much area does one can of Flex Seal cover?
Answer: One can of Flex Seal spray covers approximately 12 square feet with a single coat, but this may vary based on the surface texture and porosity. For covering larger areas or making thicker applications, plan accordingly by purchasing additional cans for your project. This is particularly useful when sealing large leaks or multiple cracks. -
Question:
What temperature conditions are ideal for applying Flex Seal?
Answer: The best temperature range for applying Flex Seal is between 60°F to 100°F (15°C to 38°C). This range ensures optimal adhesion and curing time. Attempting to apply it in lower temperatures may lead to ineffective sealing and extended drying times. So, for projects like outdoor roofing or repairs in chilly months, wait until conditions improve. -
Question:
Can Flex Seal be removed once applied?
Answer: Once Flex Seal has cured, it can be quite difficult to remove due to its strong adhesive properties. If needed, solvents like acetone or mineral spirits may help soften it, but this can take time and effort. It's important to consider this before applying, especially for permanent repairs. Evaluate whether a temporary fix or a more lasting solution is needed based on your project's requirements. -
