The Hebau fotolith system for picture engraved architectural concrete is available from Melbourne-based Actech International .
The surface-deactivator is a special formulation of the company’s Hebaunal RSEL/01 product line for exposed aggregate concrete surfaces which can be used in the printing process to apply certain modified pictures onto a plastic sheet that is then placed in the mould or form. The concrete is then poured and the next day a picture engraved concrete surface is ready to be exposed.
Fotolith plastic sheets should be stored in a dry place. They can be kept for about three months in their original packaging.
