SINIAT 13mm Watershield (formerly known as GTEK Wet Area 13mm) is a heavy-duty, moisture-resistant plasterboard engineered for internal wet areas, including bathrooms, kitchens, laundries, and commercial washrooms. It features a high-density water-repellent core, making it stronger, more durable, and more resistant to moisture than standard plasterboard.
Designed to be tiled over, painted, or finished with waterproofing systems, Watershield 13mm offers long-lasting moisture protection, reducing the risk of swelling, deterioration, and mold growth. Its thicker core provides enhanced rigidity and impact resistance, making it suitable for both residential and commercial applications.
