Note: due to its bonding properties, it’s only possible to remove Glassprimer™ glass paint from a pane of glass for up to 2 weeks after it’s been applied.
To strip any glass surface of Glassprimer™ glass paint, put down the piece of glass horizontally with the paint facing up, then cover it with conventional polyurethane paint stripping compound, either by pouring or spraying. Let the paint stripper stand for around 15 minutes. After this time, you should notice as the paint detaches and even jumps off the glass. Wash the loose paint off with water – we recommend a pressure hose – and, if there is still paint remaining, repeat the process. When most of the paint is gone, use a de-greaser and sponge to clean up the surface of the glass. If necessary, you can use single-edge razor blades to scrape the paint off. If you want to repaint the glass, you can just clean it again with isopropyl alcohol and paint it with another batch of Glassprimer™ glass paint.
