I convinced him to slide one tile up to the wall and butt the other against it followed by a few choice words and a bunch of mumbling and sighted this post as proof.
Subway tile around inside corner.
Apply mortar to the back of the tile with the notched trowel.
Depending on the tile that is to be installed and where it will be installed it is sometimes approp.
How to install a simple subway tile kitchen backsplash.
If you have to install strips of tile along the inside corner you should measure the distance from the last tile in the row to the corner making sure you take into account the expansion gap.
Repeat the process on the other side of the corner.
You would typically center the back wall so the cuts are even on both sides.
A 3 sided shower for example.
This time make the cuts at the corner so that the cut side of the tiles are about 1 8 inch from the face of the tiles on the other wall.
Generally speaking when you come to the end of a wall and you want the subway tile installation to look like it wraps onto the next wall.
Space the two tiles consistent with the rest of the tiles generally 1 8 inch which will leave a 1 4 inch space at the corner.
For instance if a tile is 3x6 and at the corner you have room for a 2 piece then the piece on the other side of the corner should be 4 to make a whole 6 tile so it looks like the whole tile is folded into the corner and the brick pattern is not interrupted.
Next spread tile adhesive on the back of the tiles and install them into position.
Press the tile against the wall with the cut side facing the corner and the other edge next to the last full tile in the course.
Work with great care as you might move the plastic trim from position.
You also need to pay attention to the inside corner tile details and patterns such as continuing a herringbone tile on the inside corner.
