If possible, it is best to use a right-angle ruler for the measurement. If there is no right angle ruler, the floor plate can be placed on four sides against the wall, and then see whether the four corners of the room are straight or not.
Which corner has a large deviation? After determining the corner of the wall, the non-integral floor is usually hidden in the wall far away from the door or under the furniture, so it looks more beautiful. But the corner of the room is usually not 90 degrees right angle. If you want to install it in this way, it will lead to poor construction, especially when you are installing, there are not so many tools to use.
Therefore, if you can find the right angle wall corner, you should start from the right angle wall corner. If the wall corner is not standard, you should start from the sharp corner with a large deviation. Welcome to any inquiry or trial orders ."
