Review: Effective at fixing leaking water butt - Fixed the leak from my waterbutt. Made sure it was dry and sprayed both the inside and outside where the crack was a couple of times. No leaks since. So good value- much cheaper than a nee water butt.

## Questions & Answers

**Q: would this work on a plastic garden water feature**
A: I have used this successfully on plastic guttering that was leaking so would expect it to work on water features. It should be applied when the feature is clean and dry.

**Q: Will this work on the indoor ceiling of an outdoor garden shed to stop water seeping in through old felt roof?**
A: Unlikely long term once water gets under the old felt it can go anywhere. Better to replace the felt..it’s not that difficult or expensive 🤗

### ⭐⭐⭐⭐⭐ Effective at fixing leaking water butt
*by K***O on 21 June 2026*

### ⭐⭐⭐⭐ as desribed

good

### ⭐⭐⭐⭐⭐ No more leaks
*by A***E on 2 December 2025*

My shower was leaking from an area that was hard to get to without taking everything apart. I taped around the area and used this spray about four times leaving half an hour between coats. It worked. Would recommend this product as easy to use if you are careful. Practice first so you can judge strength and direction of spray. It dries very quickly with little smell. Hopefully it should last a good while.
