Glass is very difficult to paint and, at best, should be considered a temporary solution. Glazed tile is often painted as a way of changing the color. Sandblasted glass, as opposed to smooth transparent glass, affords better adhesion to paint.

Painted glass often is subjected to heat shattering due to excessive absorption of heat by dark colors applied to glass and exposed to sunlight (i.e. showrooms). If painted, always coat the outside surface to minimize heat shattering.

Emulsa-Bond and XIM specifically claim adhesion (priming) on glass or tile, providing a “bonding coat” that can then be top coated with oil or latex products to extend the life of the coating.
