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.

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 !

Strong tape

Easy to use, can be cut to size. Sticks to clean surfaces. It is waterproof and sturdy. Worth the price. I was able to fix many outstanding jobs. Can be used outdoors.

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.

Every time it rains, the lean too gets wet. I have tried many things to try and stop the rain getting in. This seems to have done the trick. The tape is manageable and easy to rip.

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 got this to cover the clout-head nails that are holding down my shed-roof felt. That seems to be a place where water gets in.Being February with cold and damp weather, I applied my blow-torch to the existing roofing felt to warm it up and dry it out, then applied this waterproof strip. On a cold February day at least, It's not too messy when you first handle it, although the backing paper is a bit flimsy and keeps tearing. Once in place on the warm felt, the glue seems to get more "guey", especially when you apply a little heat to help it on its way.So far so good. It stuck in place well and it feels like its going to work.
