## Questions & Answers

**Q: Can this be used on a log cabin felt roof that has a small leak around a tack or nail**
A: I would imagine so. I used this seal on a shed roof that had umpteen leaks and, 2 years on, the roof has not leaked  again yet! Hope this helps.

**Q: How much in each tin?**
A: There is 1 litre in the tin and it's very thick. It certainly works. It has stopped the leak I had in my bay window flat roof

**Q: Can this be applied to the inside of the garage roof to a very small leak? Getting onto the roof is likely to make it worse.**
A: I did try some on the inside of the side building first when the weather was dry... like dry not raining a couple of days then dry for a day. After that I went outside and on top. Worked ok I guess.

**Q: Is this matt or gloss? what's the finish like on s felt roof? also how many layers do we need?**
A: Mine has dried a mat finish. I gave it two coats. 
It’s hard to describe the finish but it’s quite hard to what I was hoping. Think I was expecting a more rubbery finish. Seems to be ok though and no cracks appearing.

    Does the Job

I've used this product for painting over leaks in my shed and garage roof. The garage was concrete sheets with a leak somewhere on an arwa of flashing. Two coats and has been good for 6 months now.  The shed was a metal sheet roof with a leak where the two sheets overlapped. Couple of coats on the join and solved.Also used for waterproofing a bit of concrete where pooling water ended up masking the garage floor damp. Early days but looks good there too.I finished the tin and am now ordering a second to have in stock for any issues over the winter.I used the 1L tin. Doesn't cover a huge area but a nice solution Would recommend. Jus
