Presentation wall for e.g. photo projection, has surface in which magnetic detention zones are integrated, corrosion-resistant magnetic plates are embedded on rear side of wall plasters, and iron chips and powders are mixed in wall coating

摘要

The wall has a surface in which magnetic detention zones, which are freely scalable, are integrated. Corrosion-resistant magnetic plates made up of sheet steel are embedded on a rear side of a wall plasters by detention interfering coatings. Iron chips and iron powders are mixed in a wall coating as magnetic aggregates. A carrier layer is provided with a bonding agent having corrosion-resistant characteristics e.g. cement or synthetic resin.
