75× 150 tiles should be hung on the wall. According to the relevant public information, if you don't want to actually lay the tiles, it is ok to dry hang the tiles. First of all, you should buy a dry hanging board hook in a building materials store, and then measure the position according to the appropriate size when you go to the wall and tie it to the wall. Dry hanging methods of ceramic tiles can be divided into back-grooved porcelain, back-bolted porcelain and buckle-grooved porcelain. The back-grooved porcelain is connected with pendants, and ceramic tiles are installed on the base surface. The back-bolt porcelain is installed on the base surface through drilling equipment, and after screwing in the screw, it cooperates with the taper hole to form a stress-free convex fit, while the buckle-groove porcelain is slotted on the upper and lower sides of the porcelain plate, and then installed through pendants.
