A watercolour with a discoloured paper support

This watercolour of a rural scene had been mounted with an acidic card backing and window mount, and exposed to light for many years. Contact with acidic card, and exposure to light both damage paper and cause it to discolour, and this was very evident in the watercolour. To conserve the work we removed the acidic card, and washed the watercolour to reduce the discolouration. We then pressed the work to flatten it, and mounted it in good quality acid-free buffered card before returning it to the owner to be framed.

The watercolour adhered to its damaging acidic card backing The watercolour after treatment to remove the card backing, and reduce the discolouration in the paper.
