Diagonal installations offer a distinct aesthetic but demand precise geometric layout. Begin by snapping a chalk line across the room at the desired angle, typically 45 degrees. Use the 3-4-5 triangle method to ensure the line is perfectly square to the primary walls. The first row must be anchored securely, often using a starter strip or temporary blocking, to prevent shifting during the initial installation phase. Accuracy during the layout phase is crucial, as errors will be magnified across the room.
