I'm looking to tile a relatively small area floor (about 4 sq m) with ceramic tiles 300x100 mm, 10mm thick. There are two main types of tile levelling systems that I've seen: clip and wedge
and the screw-cap type ones
What are the practical differences between the two? How to choose one or the the other? Or is this purely down to what I prefer to work with?
