Re: [teacherartexchange] plaster and tempera

Tempera paint does not have a binder that will adhere to plaster. It would chip off a plaster wall as well.

To save those projects I would dilute white school glue with enough water to make it spreadable, and, with a wide brush, coat all the painted projects. The glue might act as a seal.

in the future, use a acrylic paint for those projects.
