General:
Glass does not present a very good surface for painting as it is extremely smooth. Nevertheless, extensive painting, mainly in the form of signwriting is carried out on glass using High Gloss Enamel and frosting using Semi-Gloss and Matt Enamels or Plastic Emulsion paints. Whenever possible, glass should be painted on the unexposed side.
Preparation:
New:
Wash down well with a suitable concentrated detergent solution to remove dust, dirt, greasiness from handling, etc. Wipe down glass using methylated spirit and clean cloths.
Previously painted:
Remove existing paint by scraping, or with Dekro Super Paint Stripper. Then proceed as for new work. If in good condition, clean down thoroughly with a suitable solvent to remove dirt, grease, oil, etc. Sand glossy surfaces. Dust off.
