Picture Restoration

by Feb 20, 2017Restoration

When we look at the restoration of a picture there are many considerations to take into account before decisions are made.

Material / Canvas

We need to look at the material which the painting has been painted onto and the type of paint used. Most surfaces are stable and can be worked onto directly although in some cases if the picture is painted onto old canvas it may have to be adhered to a new piece of fabric.

Discolouration

Most discolouration is due to the old varnish deepening in colour to a golden yellow or a dark treacle tone which is a problem caused by the composition of some old varnishes. We will usually clean a small test corner to see if we are likely to encounter any problems before proceeding with the full cleaning process.

It may be that old paint has darkened which is much more of a problem and is often caused by old cigarette smoke.

Back Lining

If the canvas is old and not stable it may have to be adhered onto a new piece, a process called “back lining”, or holes patched with new canvas.

Finishing

Once the cleaning process is finished the picture will be left to dry for a few days and then finished with a coat of varnish which will have a gloss, satin or matt finish.

 

The image above shows the difference in colour after restoration work has been done. The cut in the canvas was also repaired but, unfortunately, the camera on which that image was taken was stolen from the shop.
