Given the emergency nature of the problem I was impressed it adhered to a damp surface.

Needed to fix a leaking shed roof. Sufficiently gloopy to cover roofing seam well without problems. Yet to do full waterproffness test (i.e. waiting for a very rainy day), but looks good so far.

Poor / Unsuitable for “Emergemcy” repairs.

Temp was around 10 degrees so above the minimum of 5 and still took an age to dry, this did not want to go on easily unless the roofing felt was speckless, what roof is? Found an alternative for more affective than this so won’t be buying this again. Seems it might be fine on a brand new roof or spotlessly clean roof with micro cracks but anything more and it simply is not suitable.

Ladder imprints in flat roof felt. Not sure if felt had been pierced but I put two coats of this on just in case. Give it a good stir and it is easy to paint on. Have not touched it for a few days but looks good.

I don't know how well it works in the long run, but it does a really good job of filling holes and bonding. I used it with fibre glass matting to cover some holes and was very happy with how well it worked.

Good product for sealing small cracks. Very viscous but standing tin in warm water makes application easier. Promptly delivered next day.

Even in cool conditions it was easy using an old brush, the cool condition caused a slightly slower time before applying a second coat. I don’t think that this second coat was necessary but as there was some left in the tin I decided to use it.

Works well
