Geltin used in Restoration

Masterful architecture has fascinated people for centuries.

However, no building can be expected to last forever – from time to time it has to be carefully repaired and refurbished. When restoring such historical buildings, experts often make use of the natural elastic binding properties of GELITA special gelatines, which are used e.g. to treat the surfaces of ornate stucco. This technique of fine priming comprises a number of highly complex steps but is effective for restoring stucco marble. Between the various grinding stages warm gelatine is applied using a natural hair brush and the surface then further processed.

Thanks to our special gelatines, monuments such as the Opera House in Dresden, and the Alexander III Bridge, the largest in Paris, are able to be seen in their original grandeur.

In the field of book restoration gelatine can be used in a number of ways. Since the middle of the 19th century paper has been manufactured from wood. However, the acid wood glue used at the time tends to become brittle in modern archives and libraries. Today, gelatine is used in book restoration as a "natural glue" for repairing such brittle patches or for reglueing pages. Gelatine can also be used for fixing the color and typescript of historical texts. The famous Dresden Music Scores that were damaged in the floods of the year 2000 were restored with the help of gelatine.
