Customer Questions & Answers
-
Question:
What surfaces can Flex Paste be used on?
Answer: Flex Paste is suitable for a variety of surfaces including wood, metal, plastic, and concrete. Its versatility makes it ideal for interior and exterior applications, allowing users to fill gaps, cracks, and holes on walls and other surfaces effectively. For instance, if you have a leaking gutter made of metal or a cracked brick wall, Flex Paste can seal the imperfections, block water and air, and provide a durable finish. -
Question:
Is Flex Paste paintable?
Answer: Yes, Flex Paste is paintable once fully cured, making it an ideal choice for finishing up repairs seamlessly. After applying the putty and allowing it to dry, you can easily paint over the sealed areas to match your existing decor. This feature is particularly useful for DIY enthusiasts looking to repair walls without leaving noticeable marks. -
Question:
How does Flex Paste block out water and air?
Answer: Flex Paste forms a waterproof and airtight seal upon curing, thanks to its unique formulation that expands to fill gaps and cracks. This characteristic is crucial for preventing moisture infiltration, particularly in basements or external walls exposed to weather. For example, using Flex Paste in any exterior wall joinery can minimize water intrusion and help maintain a dry environment indoors. -
Question:
Can Flex Paste be used outdoors?
Answer: Absolutely! Flex Paste is UV resistant, making it ideal for outdoor projects where it will be exposed to sunlight and varying weather conditions. Whether sealing cracks in exterior walls or repairing outdoor furniture, its durability against harsh elements ensures long-lasting results. Homeowners can trust it to protect their outdoor surfaces from decay caused by moisture and UV damage. -
Question:
How quickly does Flex Paste cure or dry?
Answer: Flex Paste typically cures within 24 to 48 hours, depending on environmental conditions such as humidity and temperature. This curing time allows the putty to strengthen and ensure that it adheres properly to the surface. For speedy repairs, minor applications may set quicker, allowing you to apply the next coat of paint or finish sooner. -
Question:
Is Flex Paste suitable for filling deep cracks?
Answer: Yes, Flex Paste is effective for both shallow and deep cracks. Its thick consistency allows it to even fill larger voids, providing robust structural support once cured. This makes it perfect for extensive repairs in foundations or walls. Besides, by applying multiple layers, you can achieve a smoother finish while ensuring deep gaps are accommodated. -
Question:
Do I need to prep the surface before applying Flex Paste?
Answer: Yes, it is advisable to clean the surface thoroughly by removing any loose debris, dirt, or moisture before applying Flex Paste. Proper surface preparation ensures optimal adhesion and improves the longevity of the repair. For instance, when working on a previously painted wall, scraping off peeling paint will enhance the bonding of the putty and enhance the overall finish. -
Question:
Can Flex Paste expand and contract with temperature changes?
Answer: Yes, Flex Paste is designed to withstand temperature fluctuations, allowing it to expand and contract without cracking or losing its seal. This quality is especially beneficial for exterior applications where temperature variations are common. It ensures ongoing protection against the elements while maintaining the integrity of the repair throughout seasonal changes. -
Question:
What is the shelf life of Flex Paste once opened?
Answer: Once opened, Flex Paste maintains its effectiveness for several months if stored properly in a cool, dry place. Keeping the lid securely fastened is vital to prevent drying and maintain quality. It’s a good idea to regularly check the product before use, ensuring it remains workable for your future DIY projects or repairs. -

Flex Paste Sealers Editorial Review
**** Flex Paste presents itself as a robust solution for waterproofing and sealing a variety of surfaces, and customer experiences emphasize its versatility and effectiveness in numerous scenarios. Users have successfully employed the product for significant repairs such as patching roofs, sealing cracks in bathtubs, and even addressing leaks around water fixtures. Many have praised its thick Consistency and resilience under different weather conditions, with some noting successful applications despite challenging circumstances, such as high humidity or cold temperatures. However, the product's effectiveness seems contingent on the user’s approach and the specific conditions of application. Some customers encountered issues with leaks persisting even after multiple applications, leading to frustration and ultimately reverting to traditional repair methods such as replacing damaged pipes. There have also been complaints regarding the product hardening in its container, especially when sold in the older plastic tub packaging, which compromised usability. Those who have received the newer, Stay Fresh container generally report a significant improvement in the product's workability and longevity, indicating the importance of packaging in maintaining its integrity. Despite mixed feedback on its performance and the necessity of proper application, Flex Paste stands out due to its unique market offering and adaptability across various surfaces. Overall, while there are notable downsides related to usability and leaks under certain conditions, many users find Flex Paste to be an essential tool in their repair arsenal, particularly for less conventional applications. **
