Review: Excellent - Works very well, takes some time to cure so to speak but works instantly, I have used this during the rain and instantly stopped the leak in my roof, excellent product, used when replacing the roof on my garage with onduline
Review: It's black, it's sticky, it's very messy - Used to do temporary repair to felt on a shed roof. As others have said, not easy to get out from tube, despite keeping it warm in the house for two days prior to use + warming in hot water on the job. Forget trying to spread it, just squeeze out lengths of it. Bought two tubes, which arrived promptly and were reasonably priced. Managed to stick down the felt, it definitely got harder to do as time went on, as it was extremely cold outside early January 2024..... However, it did the job. I had no option, btw, this repair was necessary.

## Questions & Answers

**Q: Can this sealant be applied to wet or damp surfaces such as inside a plastic gutter? If not anything else suitable?**
A: Yes it can. I've used this on a gutter joining bracket that was full of water, the join on one side would keep separating, I put this underneath with water still in the gutter and holds together nicely and no leak.

**Q: Is this good and strong to seal black felt loft lining under tiles?**
A: I would leave your felt alone especially if its brittle. If you have a leak you need the tiles fixing. There is not much you can do from underneath. If you have a leak near the edge at the bottom part of the apex, I would consider a roofer removing the bottom row & re-bedding the tiles. Replacing the felt for a modern equivalent. This all depends on your roofing tiles.

**Q: how long does this take to dry and can it be overpainted with plastic gutter paint**
A: It wouldn't paint as it stays tacky. Everbuild clearfix would be better if you want to paint it. Clearfix skins over in approx 30 minutes.

**Q: Can this be used to attch pigeon spikes to roof tiles?**
A: No I wouldn't think so, it is very runny. Plus this was used to stick a guttering downpipe. It did work, but now leaks again.
