WaterShield is commonly used as a water resistant wall and ceiling lining and as a substrate for tiles in internal wet areas such as bathrooms, showers, toilets and laundries.

WaterShield may also be used as the wall lining for indoor swimming pools provided a waterproof membrane is applied over the wall.
