How to Prepare Plexi-Glass for Hot Glue
- 1). Wipe down the plexiglass with a damp cloth to remove any dust, then dry it with a dry, clean cloth that does not contain any lint.
- 2). Use a fine grit sandpaper to rough up the surface of the plexiglass where you will apply the hot glue. This will make the glue stick more firmly to the surface of the plastic.
- 3). Wipe down the surface of the sanded plexiglass with the damp cloth once more to remove any grit generated by the sanding. Dry the surface with the dry, lint-free cloth.
