Pastel drawing &
Print restoration in NZ

Temperature affects the speed of the chemical reactions leading to the deterioration of paper, i.e. in watercolours, drawings and prints. Fluctuations in temperature speed up the rate of deterioration, leading to brittleness and darkening of the paper.


The brown spots called 'foxing' are often a sign of a poor environment. These stains are caused by bacteria or mould which generally grows on paper when the humidity is high, or when there are metallic particles in the paper as a result of the papermaking process. Some papers are more prone to foxing than others.


Some papers, mats or backing boards are made from wood pulp, which is acidic and can damage the artwork over time, turning it yellow or brown. Mat lines (mat burn) may appear due to acidity of mat boards leaching into a picture.


Mould growth can be a particular problem with pastels, due to the nature of the pigment and fluctuation of temperature and humidity.

Water-damaged art

If your artwork has been damaged by water (in a flood or after a fire), left untreated, it can provide a fertile breeding ground for mould, which over time will continue to deteriorate the artwork. It is important that you act sooner rather than later to get your art work restored.

We also restore art works damaged by fire or smoke.
