Gelatine Size (Bovine – Crystal Form)

A high-quality bovine gelatine supplied in crystal form, traditionally used as a size in the preparation of paints and gesso grounds. When dissolved in warm water, gelatine forms a natural adhesive binder that regulates absorbency, consolidates friable substrates, and provides a key for subsequent coatings. It is an essential component in traditional gesso and distemper recipes, where it binds chalk or whiting to create a smooth, durable surface for decorative finishes.

Compatible with a wide range of historic paint systems, gelatine size is valued for its reversibility, permeability, and proven performance in conservation and decorative work. Ideal for use on timber, canvas, and plaster substrates where a controlled, traditional ground is required.
