Task D-14 Prepares for application of wall coverings
Task Descriptor
Painters and decorators must treat the substrate before applying wall coverings. This is done to ensure that the surface is smooth and sealed. It is crucial to ensure moisture levels of the substrate and temperatures and humidity levels are to manufacturers’ specifications. The wall covering material must be inspected, acclimatized, measured and cut in preparation for hanging.

Task D-15 Applies wall coverings
Task Descriptor
Painters and decorators apply different types of wall coverings such as wallpaper, vinyl, veneer and fabric. They also repair damaged wall coverings.
There are many factors to consider when installing wall coverings such as temperature, humidity, air movement, types of wall coverings, and types of adhesives and substrates. These factors affect materials as well as application techniques.
