Conservation Backing Paper is an acid-free paper used to seal the back of a framed artwork or document. Its purpose is to protect the contents of the frame from dust, insects, pollutants, and other environmental contaminants, while supporting long-term preservation.

Purpose and Benefits

Dust and Dirt Protection: Prevents airborne particles from entering the frame.
Pest Barrier: Discourages insects from reaching the artwork.
Environmental Buffer: Helps reduce fluctuations in humidity and limits exposure to airborne contaminants.
Professional Appearance: Provides a clean, finished look to the back of framed pieces.

Material Characteristics

Typically made of acid-free, lignin-free paper to ensure long-term archival safety.
May include buffered paper containing calcium carbonate to neutralize acids from environmental exposure.
Durable enough to withstand handling during framing and installation.

Application in Framing

Conservation backing paper is cut to size and adhered to the rear of the frame using tape or other secure methods. It is commonly applied in both gallery and home framing to provide a protective seal for prints, photographs, paintings, and documents.

Best Practices

Always use acid-free or archival-grade backing paper to prevent chemical damage over time.
Ensure the paper is applied flat and securely to prevent wrinkles or gaps that could allow dust or insects to enter.
Combine with other conservation materials such as acid-free mats, UV-filtering glazing, and sealed frames for maximum protection.
Regularly inspect frames for tears or detachment of backing paper, especially in high-humidity or dusty environments.
