Title: Composite flexible sheet for lining structural walls - using both mineral and organic binders in their substrate
Inventor: MACE JACQUES
IPC: E04H15/52
Filed: 1974-06-11
Abstract: Composite structural rendering comprises a layer of water bound binder material mixed with some organic binder material and laid up on a flexible film which is water-permeable or is perforated. It is used as a prefabricated dressing which may be applied directly in lieu of plaster to structural walls which have naturally or locally rough surfaces, e.g. marks on cast concrete from supporting cladding, and generates a smooth, decorative finish without requiring preliminary prepn. of the surface of the supporting structure. The film is a dimensionally more stable support during application to the structure than woven textiles used by prior arts. The film does not cause local variations in water absorption which would impair the hardening of the wet cement. The organic binders support the dressing while the wet material dries out.
