Temperature & relative humidity Fluctuating environmental conditions cause expansion and contraction, leading to slacking, cracking and flaking. Ensure the room temperature is 20 degrees Celsius and reduce relative humidity to 55 percent. Do not turn your air conditioner on and off frequently. Encourage air circulation and add non-acidic protective backing boards to artworks.
Atmospheric pollutants Dust and dirt can damage the surface of your paintings and are difficult to remove safely. Feather dusters can scratch paintings, so to clean use only soft-bristled Japanese or sable brushes, such as a makeup brush. Never try to clean a painting yourself, or use any liquid or commercial cleaners on a painted surface as this can cause irreversible damage. Consider protective glazing and conservation framing by a conservator for paper artworks.
Lighting Light damage is cumulative and irreversible. Direct sunlight can fade pigments, so block the sun's rays with shades, blinds or curtains. Also, don't attach lighting above paintings or on the top of the frame, it will only illuminate and heat the painting unevenly. Indirect natural light, recessed lighting or ceiling-pointed spotlights are best for home installations. Halogen lamps emit high levels of ultraviolet lights - damaging to artworks - and should be fitted with a UV filter. Light levels should not exceed 30 lux.
Micro-organisms Don't store paintings in a dark, humid place with no air circulation, as this promotes moulding and foxing - the yellowing of paper. Such damage can only be treated by a professional conservator, but will return if you don't maintain a proper environment afterwards. Renate Kant Studio, Tel: 9680 3534
