## Description

fowong Waterproof Tape Aluminium Foil Butyl Tape, Waterproof Tape for Leaks and Outdoor Use, 50mm(W) x 5M(L) Flashing Tape for Roof Sealant Tape for Repairing Crack, Gutter, RV Repair : desertcart.co.uk: DIY & Tools

Review: Effective Waterproof Tape with Versatile Applications - I recently used the Fowong Waterproof Tape for various sealing projects and here’s my detailed review: Pros: Strong Adhesion: The butyl tape offers excellent adhesion, sticking firmly to a wide range of surfaces, including metal, glass, and plastic. It holds up well in both indoor and outdoor applications. Effective Waterproofing: This tape performs exceptionally well in sealing leaks and preventing water ingress. It's ideal for roof sealant, window frames, and boat repairs, providing a reliable barrier against moisture. Generous Length: With a length of 5 meters, the roll provides ample tape for multiple projects or larger areas, making it a good value for the price. Ease of Use: The tape is easy to apply, thanks to its flexible nature. It conforms well to irregular surfaces and can be cut to size with regular scissors. Cons: Width Limitation: At 100mm wide, the tape may be too broad for smaller, more detailed applications. For narrower gaps or precision work, you might need to cut the tape or use a different size. Initial Stickiness: While the tape adheres well over time, some users might find that it takes a bit of time to fully set and bond. It’s important to press down firmly and ensure good contact during application. Durability in Extreme Conditions: Although the tape is generally durable, it may not hold up as well in extremely harsh weather conditions or intense UV exposure over extended periods. Regular checks and maintenance might be needed in such environments. Conclusion: The Fowong Waterproof Tape is a highly effective solution for sealing leaks and waterproofing various surfaces. Its strong adhesion, ease of use, and generous length make it a versatile tool for both DIY enthusiasts and professionals. While it might have some limitations regarding width and initial stickiness, it performs well for most sealing applications. If you need a reliable waterproof tape for outdoor or indoor use, this product is a solid choice.
Review: fine - I have just used this item and it seem to have stuck down quite firmly. It feels like good quality. Only the test of time will prove if it stays stuck to where it is placed. I wish the amount of tape on the roll was longer because it runs out very quickly, causing one to spend more and more to get it to fit an area. Apart from that from what I have seen so far, I would recommend it.

### ⭐⭐⭐⭐⭐ Good tape for water leaks
*by D***K on 14 September 2025*

Great tape. Really thick, strong, easy to apply. My canapé had some leaks due wall irregularity. Despite I applied previously sealant, still dripping some water. So, I got this tape. It seems a good sealant. I made double to give a nice finish to the canapé. Now, only time will tell if it is really water proof and long lasting. Very please so far.
