Great stuff, as described

Works very well, if you follow the instructions. Certainly better than some other ones I've used. Note on other reviews says grey colour fades, instructions do say to paint it if its going to be in direct sunlight. Good value for money. Remember to wear gloves, and cover anything you don't want it on, as it sticks very well !!

I used this product to patch holes in a deteriorating shed. The shed had water damage, which caused holes to form. This was a easy, cheap and satisfying temporary solution.

just waiting for it to rain so I can see if it has all sealed but seems ok

Goes to crevices and very strong. Can trim off excess
