hi just to let u guy know ive tryed these and there useless, they create voids under the tiles, i tryed them on a perspec sheet it just leaves on tile with a viod . there ok but not to be trusted. just plenty of prep work and plenty of level usage
We all know that leveling systems are a load of rubbish.
but some times you need to pull a tile out by 0.25mm to 0.50mm to eliminate lippage at one point, in this case you may use a sucker plate or on a riven finished tile/stone the 'allen key tool'.
