Tiles that are large and heavy can be fixed on walls just like smaller standard types of tiles. However, heavy tiles have a tendency to fall or slide down the wall from additional weight. Heavy tiles can be prevented from falling off the wall when they are installed properly. You can fix heavy tiles on walls by first determining what type or style of tile that you want to use in the room.

Set the tiles against the wall to see how they will fit. This is known as a "dry fit" to see if any of the tiles need to be cut to fit properly.

Trim the spacer lugs from the edges of the tiles, if necessary to have them fit without having to cut the tile. You can trim the spacer lugs with a tile nipper.

Dip the trowel in a bucket or thinset or mortar and then apply it to bottom section of the wall. Spread the thinset with the notched side of the trowel.

Apply thinset to "back butter" the back of the tile and then set the tile onto the wall. Press firmly to adhere the tile to the thinset. Repeat this process to apply the first row of tiles to the wall.

Place tile spacers under each of the tiles to support them so they do not slide down the wall. These spacers will keep the tiles in place and also leave a joint for the grout.

Repeat Steps 4 and 5 to fix the next row of tiles in place on the wall. Insert spacers in-between the tiles to support them on the wall. Continue this step until you have fixed all of the heavy tiles on the wall.

Let the tile set overnight to allow the thinset to dry and then remove all of the spacers from in-between the tiles.

Apply the grout into the joints of the tiles with the grout float. Clean the excess grout from the tiles with a damp sponge to complete the project.
