Moisture-Resistant Walls: Greenboard, Cement Board, and Backer Choices for Baths clarify where each substrate belongs in NYC and Long Island bathroom renovations

Moisture-Resistant Walls: Greenboard, Cement Board, and Backer Choices for Baths clarify where each substrate belongs in NYC and Long Island bathroom renovations. Use cement board or approved backer with waterproofing membranes inside showers, reserve moisture-resistant drywall for dry walls and ceilings, and detail seams to stop vapor leaks. In apartments, coordinate inspection timing and ventilation; on Long Island, tie waterproofing into heated floors for comfort. Correct layers prevent mold, protect finishes, and satisfy inspectors.
