Abstract
Contractors who apply coatings as a water resistive and air barriers for a wall assembly will be more effective if they understand the basic building science principals behind bulk water intrusion in walls. Understanding the leak triangle and utilizing he Three ‘D’ approach – Deflect, Drain, Dry – will help the contractor be more effective in analyzing problems and recommending solutions.
