When plasterboard gets wet, it's important to act quickly to prevent damage and mold growth. Wet plasterboard can lose structural integrity. If soaked, it may sag or collapse. Immediately remove moisture by drying the area with fans and dehumidifiers. Check for damp insulation behind the plasterboard, as it may also require drying or replacement. Professional assessment is advised to ensure the wall's integrity hasn't been compromised and to address potential mold issues, ensuring a safe and healthy environment.
