The Mist-Lining system, developed in the 1990s at SRAL by Jos van Och, has evolved into a system that today resolves structural issues presented by canvas paintings, but at the same time maintaining their integrity and authentic appearance. By determining the individual needs of each painting, a holistic approach to treating the structural needs of a painting can be integrated into a pre and post conservation campaign. This Handbook aims to give conservation professionals insight into the methodology, practice, materials and processes associated with Mist-Lining. We will guide you through the preparation of the original canvas painting for lining, the selection and preparation of the lining canvas, setting up the low-pressure envelope for executing the lining, and the steps required when undertaking a Mist-Lining. This Handbook is full of tips and tricks for the experienced practitioner, and should be used as an aide memoire for those who have some knowledge of the Mist-Lining system. SRAL regularly holds workshops to teach and disseminate the technique. We have also produced a video highlighting the Mist-Lining practice available on our YouTube channel: https://www.youtube.com/watch?v=jU-QwEfYt44. Please also consult the Mist-Lining Materials Book for information on the materials, tools and equipment we used at SRAL to carry out successful Mist-Linings.
