Customer Questions & Answers
-
Question:
What is Permatex 81158 Black Silicone Adhesive Sealant used for?
Answer: Permatex 81158 Black Silicone Adhesive Sealant is designed for sealing and bonding applications. It can be used on a variety of surfaces including metal, glass, wood, and various plastics. Its high-temperature and water-resistant properties make it ideal for automotive, marine, and household repairs, providing a flexible yet durable seal that withstands extreme conditions. -
Question:
Is Permatex 81158 suitable for outdoor use?
Answer: Yes, Permatex 81158 Black Silicone Adhesive Sealant is suitable for outdoor use due to its weather-resistant characteristics. It can effectively seal gaps and joints exposed to moisture and UV rays, making it perfect for outdoor repair projects, such as sealing windows, fixing gutters, or securing outdoor fixtures that may encounter varying weather conditions. -
Question:
How long does it take for Permatex 81158 to cure?
Answer: Permatex 81158 typically takes about 24 hours to fully cure, although it may become tack-free within a few minutes. The curing time can vary based on temperature and humidity levels in the environment. For optimal results, it’s advisable to avoid disturbing the seal during the curing process, allowing it to bond effectively and reach its full strength. -
Question:
Can Permatex 81158 be painted over?
Answer: Permatex 81158 Black Silicone Adhesive Sealant can be painted over, but it’s essential to use a paint that is compatible with silicone. After the sealant has fully cured, lightly sanding the surface can help improve paint adhesion. This feature is useful for projects where the sealant needs to blend with existing surfaces, such as when sealing gaps in trim or fittings before applying a finish coat. -
Question:
Is Permatex 81158 food-safe once cured?
Answer: Permatex 81158 is not recommended for food contact applications, even once cured. While it is safe for automotive and household repairs, it is important to use sealants specifically labeled as food-safe for projects involving food preparation areas, such as sealing countertops or appliances. Always check product specifications for safety concerning food contact. -
Question:
Can I use Permatex 81158 on plumbing applications?
Answer: Permatex 81158 can be used for certain plumbing applications, such as sealing around pipes and fixtures. However, it is best for non-pressurized applications and areas subject to temperature fluctuations. For water supply lines or high-pressure systems, it is advisable to select sealants specifically designed for plumbing tasks to ensure longevity and a secure seal. -
Question:
How should I store Permatex 81158 after opening?
Answer: After opening, Permatex 81158 should be stored in a cool, dry place with the cap tightly closed to prevent it from drying out. For best results, use the sealant within a specific time frame to ensure optimal performance. Avoid exposing the tube to extreme temperatures or direct sunlight, as these conditions can compromise the quality and effectiveness of the adhesive. -
Question:
Is Permatex 81158 easy to apply?
Answer: Applying Permatex 81158 is straightforward, as it comes in a handy tube with a precision applicator tip. This allows for controlled bead placement in hard-to-reach areas. To use, clean the surface, then apply the sealant directly to joints or gaps. It’s ideal for DIY projects where a reliable seal is needed, whether in automotive work, home repairs, or crafts. -
Question:
What color does Permatex 81158 dry to?
Answer: Permatex 81158 dries to a black finish, making it less visible for applications where aesthetics are a concern. This color is beneficial for automotive and outdoor repairs, providing a seamless look when applied between parts or fixtures. The black color also conceals dirt and grime, helping maintain a clean appearance over time. -

Permatex Adhesives Editorial Review
The Permatex 81158 Black Silicone Adhesive Sealant is a versatile product that can be used for various purposes. It is easy to apply and provides a neat finish. It can be used to seal drainage holes in resin planters, improve the seal of convertible tops, fix cracks in car dashboards, and even attach car emblems. However, it may not be the best choice for repairing torn furniture or bonding fiberglass. The sealant can be easily removed if caught before it cures, but it may leave a light film on surfaces if not cleaned up immediately. Overall, the Permatex 81158 Black Silicone Adhesive Sealant is a reliable option for automotive applications and other waterproofing needs.
