Glue that will work in/on wet concrete or mortar

[mail]

Dear All, I want to glue down some old tessellated tiles on a concrete or mortar sub strate. It is and will be wet or pretty damp and it is not practical to dry it out. I seem to remember that Sikadur cured in the wet but could be wron g. Does anyone know of any glues/resins that work in a wet environment? I seem to recall some mortars require water to set and have adhesive properti es. Chris

Stixall should do this - I have used it to glue down capping stones on garden walls before.

Remove any loose substrate before sticking.

Cheers

Swimming pool materials suppliers have a range of adhesives to attach tiles underwater. However, mortars based upon Portland cement should work and be a lot cheaper.
