fowong Butyl Tape Waterproof, 100mm (W) x 5M (L) Waterproof Tape for Leaks Sealing Tape for Outdoor Use Flashing Tape for Roof Sealant Window Glass, Boat and Pipe Sealing

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.

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.

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.

Tried a number of so-called self adhesive flashing tapes which wouldn't stick to timber as stated. This one is great. It's thicker that most and doesn't go brittle in sun/heat, and sticks to timber almost immediately.

At first I was pleasantly surprised how strong this tape was and it did a great job! However, after the week of sun we've just had, the sticky stuff has melted and the tape is just coming off. Disappointing as it's only been in place for just over a week. I'm sure it's perfect for indoor use, but outdoors, not so great.

Strong tape

I bought this tape to make a temporary repair to an old corrugated bitumen roof on my shed which I want to replace next summer. Despite the awkward shape of the roof sheets I found it quite easy to make a waterproof repair over the large holes which had developed in the last few years. I made sure the surface was clean and dry, and cut out appropriate sized pieces of silver tape, making sure there was sufficient overlap around the holes. I peeled off part of the backing tapes, pressed the edge of the tape down with a roller, and continued to remove the next section of backing, and rolled down the next section of silver tape, and so on. The tape adhered well to the roof, even though the air temperature was around 18 Deg C . Todate the tape has kept out the rain and if it can continue to do this until next summer , I will be very pleased !

We got a door canopy fitted but noticed that due to irregularities in the wall, there was a slight gap that would let the rain drip through. Not much fun on a rainy night when you’re trying to get the key in the lock. I saw this tape and thought it would be heavy duty enough to cover the gap and keep the rain out. It hasn’t rained yet, but it seems to be sticking to both the wall and the plastic canopy well.
