Wallpaper Decoration Restoration Protocol

To authentically restore a wallpaper decoration from before the 1970s, it is essential to use traditional techniques such as block printing. Modern methods like digital printing, offset, or screen printing do not faithfully replicate historical techniques.

Documentary Research

Research is crucial to understanding wallpapers in their historical and architectural context. Remnants of wallpaper are often found in places like cupboards, behind wood paneling, or beneath stretched fabrics. The method involves careful observation and analysis of the paper layers, which can reveal hidden historical documents.

Removal and Conservation

Wallpaper removal follows strict conservation guidelines. If possible, the paper is peeled off dry; otherwise, it is gently moistened. When these methods fail, "facing" with Japanese paper is used to protect the painted layer. The documents are then dried and cleaned according to specific methods.

Documentation and Reconstitution

When the found elements are insufficient, further research in specialized collections is necessary. As a last resort, gaps are filled by drawing, requiring a deep knowledge of historical styles and printing techniques.

Digitization and Block Engraving

The documents are scanned and digitally restored, then vectorized for digital engraving. Each color and shape is drawn using Bézier curves, respecting the specifics of block printing. The blocks are then created from composite materials and engraved with precision.

Preparation of Colors and Paper

The colors are prepared using the traditional tempera technique, with natural pigments and rabbit skin glue. The paper, conforming to conservation standards, is coated with the base color on a large table before printing.

Block printing is done color by color, with particular care taken at each stage. Other techniques, such as toning and embossing, add textile effects or relief to the wallpaper.

Wallpaper Installation

The installation requires meticulous preparation of the walls and wallpaper. The rolls must be marked and the borders cut. The installation itself requires careful application of glue and precise handling of the paper to avoid bubbles and ensure a perfect fit.

This meticulous process preserves the authenticity and quality of antique wallpapers, ensuring a faithful restoration of this precious heritage.
