Hello:

Wish to secure a vinyl strip to a concrete garage floor entrance to try
and prevent (small amounts of) rain water from coming in.

It was suggested that I try an "industrial grade double sided adhesive
tape".
But no details as to brand or type are available.

Obviously, the adhesive would have to be waterproof.

Would you try one of the Foam Core type of double sided tapes, or without a
foam core ?
Could these (either type) possibly truly be waterproof ?

What about an RTV type of adhesive, rather than a tape ?
Or,... ?

Thanks,
Bob
