Unconventional techniques and art materials employed by modern artists can require advanced, unique conservation-restoration methods, which are individual to the specific work of art.

Pauline Boty, Celia Birtwell and Some of her Heroes, conservation and restoration of modern and contemporary unvarished paintings

Peter Koneczny has responded to the complexity of problems presented by modern and contemporary paintings, particularly by unvarnished oils, acrylics, flat field and unprimed stained canvas paintings, by developing over decades specific techniques and materials for cleaning and retouching in his studio.

The B72 Retouching Gels he has also researched and developed are indispensable media for the retouching/inpainting of modern and contemporary works of art.  They allow the conservator-restorer to imitate idiosyncratic painting materials and techniques used by modern and contemporary artists.

B72 Retouching Gels and their properties and applications were presented at the Retouching Complex Surfaces Conference at the Courtauld Institute of Art in London in 2007. The talk ‘Paraloid B72 Gels as media for retouching’ was presented by Patricia Smithen (conservator of modern and contemporary paintings at the Tate Gallery, London).

The difficulty with matching colours when retouching modern paintings is that many of the 20th century synthetic organic pigments and some inorganic pigments used in artist’s paints are now obsolete and no longer available.

Peter has addressed this problem by collecting and creating one of the world's largest collection of pigments which includes unique samples of many obsolete modern pigments. With a range of over 1600 pigments, Peter is able to match almost any colour, which is of particular importance when retouching flat field paintings.

John Hoyland, acrylic, unprimed stained canvas paintings

The cleaning of modern and contemporary paintings requires an approach that is different from that used for traditional paintings. Peter has developed techniques for the removal of varnish from solvent sensitive paintings, and cleaning techniques for unvarnished paintings which include acrylics and unprimed stained canvas paintings.

Enrico  Castellani, Superficie Bianca,  conservation and restoration of modern and contemporary complex paintings Otto Piene, Rauchbild, conservation and restoration of unusual media paintings

Peter has restored a variety of paintings of both unusual construction and unusual media, such as Otto Piene's Rauchbild, 1962 created with soot from a candle.

Peter has restored stone sculptures and plaster casts by artists such as Barbara Hepworth and Eduardo Paolozzi.
