## Questions & Answers

**Q: so if i got a leak on the pipe under my tape what constantly dripping do you think this will help ???**
A: Yes. But you might need to get a narrower tape. The one I bought is quite wide as I needed it quite wide to straddle a roof-felt seam. The one I got would be too wide to wrap around a pipe beneath a tap

**Q: Can I use this product to repair a leak in a hosepipe**
A: Wouldn’t have thought it would be ideal. It’s a butyl adhesive so there’s likely to be a sticky edge. Plus, it’s quite wide and I doubt you’ll get a good deal on a hosepipe. It’s perfect for roof felt repairs

**Q: If used on a wooden shed to cover a leaking joint can it be painted to match in?**
A: I attached to dry shed and it has kept out rain but the shed stain I used has not covered the silver colour. Maybe a better covering paint may cover but I wouldn’t be sure on that. It has been very good adherence after lots of rain and winter weather though.

**Q: My motorhome has a leak somewhere around the roof vent seal against the bodywork, would applying this all the way around the edge work well?**
A: It’s exactly what I used it for, no leaks yet , it’s a great product, make sure you clean round the vent with nail varnish remover , once I applied the tape I warmed it up with a heat gun before rubbing down the seams , hope this helps !!

## Customer Reviews

### ⭐⭐⭐⭐⭐ Sticks and seals almost anything
*by R***N on 28 July 2025*

Great product this will stick to almost anything and makes a great waterproof seal. I had a plastic type birdbath that cracked over winter and started to leak. Sealed the base up with this and no more leakage. Very good.

### ⭐⭐⭐⭐ Great for sealing felt roofs on sheds
*by S***Y on 27 February 2025*

This butyl tape sealant is ideal for sealing felt on the front and rear apex of sheds.The tape is very sturdy.Ideally, you need to iron the tape down (silver side up) through a dish cloth to melt the adhesive fully onto the felt.You may also use a heat gun or hairdryer.

### ⭐⭐⭐⭐⭐ Effective Waterproof Tape with Versatile Applications
*by A***  on 13 August 2024*

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.
