## 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 🤗
