I've bought several tins of this for an old large flat roof where the felt had cracked (the owner couldn't afford for a total renewal ) Before the application of this thick creamy paste like compound there were numerous leaks from the rain. All were eliminated after a good going over with this excellent product . It's got strands of fibreglass in it so "globbing" up large cracks and splits in the felt was relatively easy. Damp conditions are no problem but try to make sure you brush away any loose debris or dirt first.
Get disposable gloves to use before you start . White spirit can be used to clean your brush afterwards if required , plus it removes any splashes or spills in the event .

I had a very old corrugated cement asbestos garage roof that leaked like a sieve numerous cracks through the material the external width of some of them was 4/5mm . Tried this product as a temporary repair before replacing roof. Have now decided to not bother with a new roof as this has completely stopped all leaks. Only down side is I received black not gray and the garage now doubles as a sauna in the afternoon. Absolutely recommend this product as a quick repair. It took a tin and a half to coat a single garage roof but in places I was applying it very generously due to the width of the cracks and that the roof surface had begun to break up.

Used to coat a lead valley 9” wide that had lots of age cracks allowing water to seep through.
Was easy to apply in dry weather and coated first time really well.
