We’ll provide tips and best practices so that appearance doesn’t become an issue in the first place. Learn how downlighting on interior and exterior walls can impact the look of masonry. We’ll discuss how to correctly use the 20' rule and touch on color ranges of materials, mortar joint profiles, and chippage of materials.

  • Know what type of lighting works best alongside a masonry wall.
