Hello tilers glad to have found this forum. I am doing a small wet-room and starting to scratch my head at a few problems. So hope I can ask for a bit of experienced advise. I have put all wall and floor work in and the tray. Used backer board the are some uneven old walls also. I have put in UFH, and tiled over it. I put a screed of flexible tile adhesive on to the ufh. before i found this forum, so hope that is ok. then mosaic tiles down. and grouted. My first question is I have started the walls, and saw a lot of advise to put silicon in the corners. 2 or 3mm. which i understand now is because it expands when warmed, so do I need to pick out the grout around the edge of the floor arr. I will try to upload a pic.
