The tile council of north america recommends at least a quarter inch gap between the tile floor and the walls.
Tiling a wall from top to bottom.
If you re only part tiling a wall a top horizontal row full of whole tiles makes for a much cleaner finish so we think it s really worth investing some time to get it right.
If your wall isn t an exact multiple of the width of a tile plus grout line start between one quarter to one half of a tile to the left or right of this line.
Never fill this gap with grout because tile grout is not flexible.
Don t start it at the floor.
When you install ceramic tile on the floor you must take care to create an expansion joint between the walls and the tiled floor.
Start applying the adhesive in a bottom corner about 1 tile length away from the bottom and side of the wall leaving space for the edge tiles.
Next apply the grout to the tile working from the bottom of the section upwards and holding the float at an angle of about 45 degrees.
Sweep diagonally across the tile forcing the grout into the joints.
If you tile top to bottom your tiles may slip why not work out where the tiles will finish put a batten then tile up if you are tiling it in one hit then should you be a little bit out it will be easy to slide the tiles up insert a piece of card in to hold them in the new position.
A batten board is nothing more than a 1 x4 or 1 x2 board screwed directly into the wall horizontally.
A batten board helps you start your bottom most course or row of tiles.
There is chances of slipping of tiles from top to lower.
In this case draw a vertical line dead centre of the wall and work in both directions from there.
Do not cover the entire float with grout.
On standard three by five shower the back wall we always start center and bottom to top so we have equal cuts in the corner then side walls we start front to back bottom to top so you also have equal cut in corner the combined corner cuts are usally just over a full tile looks great.
Theoretically tiles to be laid from top to bottom but practically it becomes impossible due to above reason.
I have used this method it worked for me.
Step 1 use a gauge rod to work out the position of the lowest horizontal row then mark the top row s position on the wall.
Instead bring it up to about 3 4 of the height of your tiles.
If you are using ppc cement mortar then do not do it because ppc cement mortar takes much more time to set and chances of slipping of tiles becomes more.
