Pigmented Wax/Resin (PWR) is ideal for filling losses in paintings. The material is easy to manipulate using moderately heated tools to quickly fill losses. The texture of canvas weave and paint can be impressed into the material to match the adjacent surface, or the fill can be sculpted to match adjacent brushwork. Cracks and other physical irregularities of an aged painting are easily replicated using dental tools.
Since the PWR fill is placed in the loss area only, there is no residue on the surrounding paint. This eliminates the possibility of ghosting in dark passages which can occur using other methods. Choosing from the 12 colours to match the paint or underpainting will facilitate inpainting. There is a set of 14 neutral greys developed for photography restoration. The balance of wax, resin, and pigment results in a hard, somewhat brittle material, that resists deformation at room temperature. The material accepts inpainting and varnish readily.
Available as single stick colours, 12 colour Assorted Set or 14 colour Neutral Grey Set.
