I've seen it over and over with Racedeck floors or similar, people start their design with a whole tile on one side and end with a odd size cut on the other. This leaving the design off centered. Racedecks how to even shows you to do it this way, It would work perfect if you floor was exactly x amount of feet wide. I guess my OCD is getting the best of me..... I understand that the first row need to be a whole tile to clip the door edging but I plan to have equal cuts on each wall when it comes to the width.
You will generally see people refer to a '
simple' method and then there is the typical set of manufacturers instructions.
The manufacturers instructions are almost always centered left to right. Find the center of the garage, work one way and then the other... Often saving all the cuts for last helps, especially if all your walls are square.
Where it all breaks down and throws perfection to the wind is front to back. With traditional polypropylene tiles you can't cut the front because you need the edges to lock the ramp pieces on.
TechFloor has resolved that issue by making multiple sizes of tiles. PVC tile manufacturers resolve it by offering a ramp edge that slides on the cut piece of tile.
