Cleaning Chalk Talk

The grainy texture of RTape's ChalkTalk® chalkboard film provides an exceptional finish for writing and drawing with either chalk or chalk ink. ChalkTalk® is perfect for use as a restaurant menu board or as an appliqué in a home environment.

In writing on either a slate surface or a chalkboard film, such as RTape’s ChalkTalk™, chalk can leave residual particles, after erasing the image using a traditional eraser. See the photo below.

The best way to remove the ghosted image is to wash the surface with a wet rag or wet sponge, as shown in the photo below.

Whether you use blackboard chalk or sidewalk chalk, all of it is abrasive to some degree. Sidewalk chalk is especially abrasive. Even after washing the surface, the abrasive particles in chalk can slightly scuff the surface, leaving a telltale mark. In most cases, this should not be objectionable.

As an alternative to using blackboard chalk, you can use liquid chalk markers to draw on the ChalkTalk™ film. See my article: Chalk Versus Liquid Chalk Markers.
