Keeping the tiles “square” to one another is a key part o
f
the installation process.
• Proper installation will have all the edges o
f
the tiles in line, with no staggering or gaps, and the entire tile edge in

ull contact
with the nei

• Measure the distance between your marks.
- If the distance is 5 feet, your corner is square
.
- If the distance is less than 5 feet, your corner has a measurement of less than 90 degrees
.
- If the distance is over 5 feet, your corner has a measurement of more than 90 degrees.
• If the walls are out of square by a large margin, you may want to balance out the difference.
• It is critical to
g
et the fi rst row of tiles strai
g
ht.
• This is accomplished by following the string line and not the wall.
• Walls can be irregular throughout a room, especially in corners.
• Trim tile to fi t as you follow the strin
g
.
• Use a scrap piece of tile to “tap in” and line up the
g
ood tile.
