Review: It just works and works well. - This was my last throw of the dice before paying out £1.8k to have my felt garage roof re-felted. Stirring it was a challenge but with a stirring attachment in an electric drill I got the correct consistency and waited for a dry sunny day and applied it. Make sure you sweep the roof clear of all debris and your good to go. It's very thick and applying it takes effort, apply liberally with a tar brush. Waited 48hrs and gave it a second coat and 24hrs after that along came Storm Amy. I was dreading going into the garage to check but after 36hrs of torrential rain I checked and it was bone dry, nothing, no water ingress at all. Do the correct prep and apply liberally and this stuff is excellent and I would recommend it to anyone.
Review: Very happy - awesome product, did the job as expected highly reccomended. Delivery was also fast

## Questions & Answers

**Q: Can i use this to seal some leaks on a epdm roof**
A: It would be advisable to use a rubber based medium on epdm rather than a bitumen based one for a lasting repair. 
Consult the epdm manufacturers for professional advice.

**Q: any good for a felted shed roof ? it's a new shed but leaks like a shive .**
A: It is a fairly low viscosity compound so not ideal for a pitched roof as it will run. I used it on a flat roof and that was fine.

**Q: Can you apply decorative gravel on top?**
A: You only really do chippings with a Bitumen gritting solution,this is a roof coating not an adhesive

**Q: Is it 'pourable' through a funnel?**
A: Depending on how large the spout is in the funnel and if it were a warm day it would run slowly through a funnel but less likely on a cold day. It will need a good stir first and then put it in the sun or in a warm room. I hope this helps, Roger Mc.
