    Covers some small cracks in shed felt and has not leaked.
  

*by K***N on Reviewed in the United Kingdom on 25 September 2020*

I have some patches on my shed roof that I wanted to cover, to save me replacing the felt completely at this time.This is fairly adhesive but best to apply in warmer weather as this helped it bond to the roof.  It was easy to apply.  I just measured the spaces I wanted it to cover and used household scissors to cut to length.  It is then as simple as removing the film over the adhesive side and applying to the roof.  Some moderate pressure is required to ensure it sticks well.This has been in my roof for over a month now and has stayed in place.  Even during some sting winds.  My shed is fairly exposed so takes a lot of battering In the wind and rain.  Not one piece has moved and the shed has remained waterproof since it was applied.This is a very handy item for small tears and cracks in roof felt but if you have big holes it will not help.I would purchase again and good value for money.

    Prodotto scadente!
  
  

*by D***I on Reviewed in Italy on 27 February 2018*

Pessima adesione, una volta tolta la carta di protezione si scopre che la quantità di adesivo presente è ridicola, non sono riuscito a utilizzare il prodotto, in quanto non v'era modo di farlo stare attaccato.
