SPG · Screen Paint Glass

Glass becomes a screen.

A field-applied rear-projection coating. Glass stays see-through when the projector is off. Becomes a sharp screen when it's on. Storefronts · lobbies · dealership walls · subway screen doors.

How it works

Light captured at the rear face.

SPG is a thin engineered coating brushed or rolled onto the back of a glass (or acrylic) panel. Project from behind. The coating catches the light at the rear face, producing a sharp, color-accurate image for the viewer in front. No flicker, no panel join lines, no special projector.

  • Reversible. Water-based, removable when the campaign ends.
  • Form-free. Apply to any flat or curved transparent surface, any shape.
  • Off ⇄ On. Projector off: glass is transparent. Projector on: screen.
🛠️

Easy installation

Roller or brush, applied on site. No factory pre-treatment, no specialty equipment. A typical storefront panel is ready the same day.

Clarity

Engineered for sharp, vivid, color-accurate projection. Even in well-lit retail and lobby environments. Glass keeps its see-through state when off.

Convenience

Reversible by design. Water-based formulation removes cleanly when you want the surface back to plain glass. Easy to retouch or change layout.
