Yes, plasterboard does swell when wet. Exposure to moisture can cause plasterboard to absorb water, leading to swelling, weakening, and potentially mold growth if not dried properly and promptly. To minimize damage, it's crucial to limit plasterboard's exposure to water and address any water damage immediately by drying out the affected areas thoroughly and ensuring good ventilation. In some cases, replacement of the water-damaged sections may be necessary to maintain structural integrity and indoor air quality.
