B72 Retouching Gels 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.
One may find on the paintings a variety of materials added to the paint or to the painting medium: hollow glass spheres, powdered minerals, broken ceramics, sand, etc. One cannot reproduce such effects using typical retouching media (low viscosity solutions of resins) without resorting to the use of materials less stable than Paraloid B72. However Paraloid B72 based B72 Retouching Gels permit the use of unusual paint filling materials. Painting with sand serves as a good example for illustrating the limitations of a normal retouching medium compared with the effects achievable by the use of Gels.
