A
ageless
Ive been searching online to find my answer but hitting a brick wall. As some of you will know, i was advised to get my hands on a S1 adhseive to fix tiles onto a wet tray. I went to 4 different tile stores and not one of them kne what i was talking about but recommended a c2te as a flexi adhesive to lay with as everytime they did a google search, this was coming up with the S1. So basically in a nutshell, can someone explain to me what S1 is and is a c2te S1 but just not printed on the bag of the adhesive.
