Wood paintings need constant attention as sometimes the wood naturally expands and contracts. If you own valued art work the ideal temperature in your home or office is around 68 degrees. On the other hand, centrally heated homes can become very dry and humidifiers might be necessary to keep the painting intake. Never place paintings above radiators or heating vents. They can cause serious deterioration of a canvas surface.
Direct sunlight is harmful to paintings.
Avoid cold walls where condensation may occur. Your fellow art collectors will recommend inspecting your pieces regularly, front and back. Inspect the surface from the bottom to the top. Try to detect minor problems like cracks or fading that could become major and expensive repairs. Paintings can be inspected in direct sunlight.
