You can make a draft on paper of your floor tile patterns. Unless you are planning out very intricate tile patterns, involving different sizes, colors and shapes of tiles, a drawing is not necessary.
You'll get better results by planning it out as your real floor tile installation.
Marking and snapping your layout reference lines will help you to lay your floor tiles in manageable sections, and keep each of your sections straight.
To begin working out your floor tile patterns, you'll first need to make two reference lines on the surface of your floor. But first, you need to measure your floor. Because you want to determine where the middle of it is.
So start by measuring the floor from two opposite walls and make a mark at the mid points of each wall where it meets the floor.
Do the same with your remaining two walls.
Use your chalk line tool to snap chalk your first reference line onto
the middle of your floor; The line should stretch across the floor from
the mid mark of one wall to that on the opposite wall,
You will then make the second line to cross over the first, by snap chalking a line from the mid marks on your two remaining walls. Your lines should wind up looking like a plus sign in the middle of your subfloor; The lines should stretch out to each of your four walls, and they must be perfectly perpendicular to each other.
It's very rare when planning a floor tile installation to find a floor that's completely square. It's a good idea to recheck all of your marks to floor surface before moving on. If you don't, you can wind up with drastic angle cuts to your edge tiles, And this will be visible to anyone who enters the room.
You want to plan your tile patterns where these cuts are hidden from view, making for a more professional looking floor tile installation.
Adjust your reference lines, so the most visible tiles will look the best. When tiling a floor, it would be the floor against the wall you first see when you enter the room.
Check that your reference lines are square and that they are at 90 degrees to each other, to do this measure and mark 3 feet on one reference line and 4 feet on the other. If the distance between the two marks is 5 feet, your reference lines are square.
If your reference lines are not square, you'll need to adjust them by moving the chalk lines slightly and re-snapping the lines.
Use a long 2x4 to trace the diagonal on the floor between the marks you just made.
Adjust your reference lines until they are square. You will need to move your chalk lines slightly and snap new lines.
If your diagonal line measured more than 5 feet, move the line in slightly clockwise, with reference to the center point. If it measured less than 5 feet, move your line slightly out counter clockwise.
Once you have your reference lines in place, your next step is dry laying a sample of your floor tile installation, so you'll know your floor plan is right.
