Gyprock Wet Area Base Coat is a moisture resistant base coat ideal for use as the first and second coat in a three coat plasterboard jointing system in wet areas.

Product Overview

Wet Area Base Coat is a pre-mixed, low VOC jointing compound with excellent tape adhesion to provide joint strength.

Used for the first and second coat in a three coat jointing system, its moisture resistance makes it the perfect choice for joints in wet areas. 
Joints may be finished with any Gyprock topping or all-purpose compound and sanded smooth prior to decoration. Where walls are to be tiled, no finish coat is required.

Typical Applications

Gyprock Wet Area Base Coat is typically used for the first and second coat in a three coat jointing system in residential and commercial walls and ceilings. It is ideal for joints in moisture resistant systems in bathrooms, wet areas and laundries. Wet Area Base Coat is designed for application with hand tools, mud boxes, automatic tapers and other machine tools.
