Make a Dry Wipe Whiteboard using Screen Goo

Today's classrooms use two principal types of visual aids: Dry-Erasable White Boards and Video Projection. Unfortunately the properties that allow a surface to be used for dry erase result in a terrible projection surface.

A white board's glossy surface causes a phenomenon called Hot-spotting. This is where the centre of the projected image is so bright that the actual projected content is obscured by a bright white glare. This leads to an all too common situation where a classroom will have white boards fixed to the front wall and a separate projection surface, usually a motorized or pull down screen mounted in or on the ceiling, which drops down in front of the white board when the lesson calls for projection.

Well, stop the presses: Goo Systems has come up with a better solution!

One of the key characteristics of Screen Goo has always been its freedom from Hot-spotting.

Our idea is simple but very effective: paint a premium Screen Goo surface on the backside of a transparent, dry-erasable substrate such as Plexiglas, Lexan or tempered glass.  This is a very simple solution to implement. Simply apply two coats of Screen Goo Finish coat first, followed by two coats of Screen Goo Reflective second and then a final coat of Screen Goo Ultra Black to capture any stray light. The result is a multi-purpose surface combining Screen Goo's exceptional video quality with a dry erase capability.

Here is what you get:
