Aquaseal is recommended for floor repairs. As I have a finger size hole in it I need to repair it. I am Germany based and I could not find it yet, starting with difficulties to identify the right type. http://www.aquaseal.com/all.html does list a range of products hard to which one is meant by Alpackas advice.
I am familiar with Seamgrip (have used it for other repairs), but I am not sure if it is totally equallent to aquaseal.
Thanks for any help,
