Can You Install Stacked Stone Over Drywall? Weight & Safety Guide
This technical report analyzes the structural limitations of installing natural stone veneer over drywall, emphasizing the risks of substrate delamination under vertical shear stress. We evaluate the 8-12 lbs/sq.ft dead load of Slate and Quartzite panels against residential framing capacities, providing a rigorous framework for substrate reinforcement using cement backer boards and ANSI A118.4 polymer-modified thin-sets. The guide covers weight-load calculations, moisture mitigation for wet areas, and the importance of rigid foundations in maintaining the CNC-precision interlocking integrity of high-volume B2B installations.
