Excellent
Used to seal leaking gutter. Product worked well I did as per instructions and success, no leak. Great value for money,easy to use, between applications left for about 15 minutes. Takes about 15 to 20 minutes on a dull winters day to dry ,I found.

As described
As described. Sprays well and does the job. Good quality. Smells really strong so would recommend wearing a mask and also covering areas around you’re spraying. Sprays well and dries quickly

Stuff is magic!
We’ve got a leaky conservatory roof & looking at an expensive replacement … used a can & no longer leaking - I’m sure it’s only temporary, but for now it’s holding & staying dry

Brilliant
My gutter was dripping from the corner joint, so I climbed up the ladder armed with this tin and although I thought it looked quite watery, I reached up and cleaned a it of debris out and then sprayed it, I then sprayed the outside of the joint and hoped for the best. The downpours that we have had recently were going to be a good test for it. The rain came and the dripping was nomore. Not bad for a lady pensioner. I had my doubts but this proved me wrong there are no drips now. Hence BRILLIANT.

Worked a treat on pesky guttering and bathroom pipes
Does what it says …….I’d buy it again for sure and at a good price.
