A vibratory suction cup has become an indispensable assistant for the tiler when laying tiles. What are its functions?
1) mix the solution to ensure good adhesion;
2) squeeze out air, bubbles;
3) sink the tile;
4) move the tile;
6) pull out the tile.
You see how many possibilities a vibrating suction cup has, in my opinion, it is especially important to use it when laying 1200 x 600 tiles, or floor tiles.
