Exterior slate tiling

[steve Lea]

Hello this is my first visit to this site.
I'm constructing a water feature
which consists of a 1000 x 1000 x 200 deep concrete block wall
which i'm tiling in stepped slate strips.

I need to cover the top of the wall with a 1000x250x35mm
bit of slate but need to glue a cover stip 1000x60 on the front
edge of the slate top to hide an led light.

Could anyone please advise to the type of adhesive i can us.

It needs to be waterproof

Thank you

Hello there and welcome to the forum. Is there any chance you could add some pics? It would make it easier for us to understand what you mean.

Hi & welcome.........what is the cover strip made of ????

im sure you can pick up a slate repair glue which sounds more like what you will need rather than an adhesive
