Refer to General Requirements > Planning section of this document. To ensure straight-square installations, apply at least two perpendicular chalk lines onto the substrate (at a 90 degree angle to each other). These chalk lines should extend the entire length and width of the area to be covered. A laser line can be also utilized for this purpose. The location and intersection point of the chalk lines should be determined to achieve the design intent and reduce waste.
NOTE: The intersection point mentioned above may or may not be in the center of a room in order to achieve the design intent.
