## Overview

Everbuild Everflex Roof and Gutter Sealant is a 295 ml butyl-based adhesive designed for multi-surface roofing repairs. Its weather-resistant, semi-drying formula ensures durable, flexible sealing on materials like bitumen, metal, slate, and wood. Easy to apply with a standard sealant gun, it performs reliably even in heavy rain, making it a top choice for professional-quality roof and gutter maintenance.

## Description

From the manufacturer HOW TO APPLY? All surfaces must be clean and free from dust, grease and other contaminants. New concrete or mortar should be allowed adequate time to dry and mature. Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut at an angle of 45° with an opening slightly larger than the gap to be sealed. Apply using a standard sealant gun. To ensure a proper bond, always smooth the sealant down with a spatula or piece of wood wetted with linseed oil or white spirits.

Review: Perfect and no BS - Fixed a Upvc leaking gutter seal, worked a treat and still going strong. Saved me listening to all the BS of a gutter repairer and getting ripped off in the process.
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.
