I attempted my first tiling job a few days ago in my downstairs bathroom. It took me around 8 hours to get to this point. The day after I came back to remove all the tile leveling clip wedges. I was left with a couple that I couldn't get out, and I also had a lot of adhesive in my grout lines. On one of the stubborn clips I resorted to trying to remove it with a pair of pliers and ended up riping the whole tile up (This was 16 hours after laying it). I got fed up and ended taking them all up. I noticed that hardly any of the adhesive was left on the floor, and was instead all on the tiles.
I used a 10mm u shape adhesive trowel and back buttered the tiles, primed the concrete screed with Mapei primer g, and used Mapei rapid set adhesive.
Firstly, should my tiles have come up so easily?
Secondly, I was really struggling to lay my tiles with no lippage in the end. Am I right in thinking this is to do with the C shape of my Vitrex tile leveling clips? My adhesive was also going off way too fast when I ran into any problems which didn't help. I did notice a small lip where the toilet used to be. Possibly 1-2mm, would this matter?
Should I try again using a slower setting adhesive, possibly leveling the floor, and a different tile leveling system or possibly just spacers? Or should I just get a tiler in?
Thanks in advance.
