Safeguarding Your Framed Artwork
Out of the light
Try not to hang pictures directly opposite large windows as sunlight fades colours and discolours paper. Special UV-coated glass can help to slow this down. The Fine Art Trade Guild has set industry-wide standards for printing and framing materials. Ask your framer about the ways in which you can preserve your artwork for the long-term.

Avoid heat

Ideally pictures should not be hung above radiators. Extreme or rapid changes in temperature cause paper and wood to warp and dry out and adhesives to fail

Beware damp
Damp can cause pictures to ripple. If the ripples touch the glass, the picture might stick and be hard to remove. Damp also encourages fungal growth - likely to show as brown stains. Conservation framing can slow these effects, but it is always best to avoid hanging framed pictures in humid conditions. Allow six months before hanging pictures on newly plastered walls.

Eye-level display
Remember most pictures are designed to be viewed at eye-level. When hanging a group of pictures of different sizes align the top edges. Groups of pictures need not be hung in symmetrical patterns, but they should follow some sort of overall design. Try arranging them on the floor first.

Hang securely
Use two hooks on the wall, each set about a quarter of the way in from either side of the picture. Check that the cord, wire or other hanger you use is designed to support the weight of your artwork. Where safety is critical, in children's bedrooms, for example, ask your framer about security fittings and glazing.

A gentle clean
Dust frames or treat with a soft brush, rather than risk applying water or cleaning fluids. Don't use cleaning fluids or water on the varnished surface of oil paintings; again dust carefully. If cleaning fluids have to be used on the glass, apply them to a duster first (rather than spraying the glass directly); take care not to let the fluids touch the frame.

Handle with care
When carrying and transporting a picture, grasp the frame firmly on both sides. If you have to store pictures, make sure they are stacked vertically and the right way up. When stacking pictures, stand them 'glass to glass' so that the hangers do not damage the frames.

Regular checks
If you find any evidence of discolouration, unsightly brown dots, small insects under the glass or that the brown paper tape sealing the back of the frame has come unstuck, return the frame to the framer. Check for corroding picture wire or weak or loosening cord. The varnish on oil paintings will gradually discolour, especially if the picture hangs in smoky or polluted conditions. It should be replaced as it dirties. Oil paintings stretched over wooden bars may sag over time and the bars can make a slight imprint on the front of the canvas. Take the picture back to your framer for tightening or re-stretching. The Fine Art Trade Guild recommends inspection every five years.
Five Levels of Framing - Museum Level
(highest specification)
Objective To visually enhance artwork and offer the ultimate level of protection from physical and mechanical damage, airborne pollution and acids generated by framing materials for up to 35 years in normal conditions. Ideally frames should be examined by the framer or conservator every five years, and there should be a label advising this on the back of the frame.

 
Suitable for Museum-quality works and artwork that is to be preserved for the future, including high value items and artwork of potential or historical value. Processes must be fully reversible.

 
Moulding No significant blemishes. Care must be taken to match the pieces. The moulding should have a rebate that is sufficiently deep to comfortably hold the sandwich. If artwork is likely to touch the moulding, this should be sealed with strips of Cotton Museum-quality mountboard or a conservation foil and paper tape.
Note: Good original frames should be retained wherever possible as these can enhance the value of the artwork.

 
Mitres Accurately cut, glued and pinned tightly. Corners to be touched-up so no unfinished moulding is visible.

 
Windowmount A windowmount or slip should normally be used to visually enhance the artwork and distance it from the glazing. If close framing is required, there should be a spacer between the artwork and the glazing and this should be made from Cotton Museum mountboard. The corners of the windowmount must be cleanly cut; the mountboard must be free from blemishes and there must be clearance of 1- 3mm inside the rebate (clearance varies depending on frame size). Only Cotton Museum mountboard at least 1200 microns thick and conforming to the Guild standard should be used. Slip moulding must be accurately cut and should not touch the artwork. Multiple mounts or deep spacers must be used to frame works with migrant or delicate pigments, such as pastel drawings, or artwork with a cockled surface. Using a fixative on pigments is not acceptable. The windowmount should, where possible, project at least 5mm over the edge of the artwork, thus holding it firmly in place. Any pencil marks on the underside of the windowmount should be rubbed out as they may come into contact with the artwork. For photographs unbuffered cotton museum mountboard should be used.
Note: Sometimes it is advantageous to retain an original windowmount (possibly gilded or decorated). In this case preferably a 1200 micron, but at least 500 micron, Cotton Museum quality mountboard barrier should but cut to fit the underside of the windowmount to within a few millimetres of the window or a few millimetres beyond the opening

 
Undermount There should be a barrier layer between the artwork and the back board; this should be made from Cotton Museum board at least 1200 microns thick. For photographs unbuffered cotton museum mountboard should be used. The undermount should be the same size as the windowmount and hinged to it along the longer side using museum-quality paper or fabric with either starch paste or SCMC (sodium carboxy methyl cellulose). Note: Artwork stuck down onto acid board should be referred to a conservator for possible removal of the board.

 
Attaching artwork The artwork should be hinged to the undermount with T-hinges on the top edge, or a similarly reversible process should be used, such as corner pockets made from naturally lignin-free museum quality paper. It is not acceptable to make hinges from self-adhesive tape; hinges should be made from naturally lignin-free, pH neutral paper and the adhesive made from starch paste or SCMC (sodium carboxy methyl cellulose). Hinges should be torn, not cut. Hinges should be weaker than, or the same paper weight as, the artwork - never heavier. Hinges should be attached to the back of the artwork, not the front, and should overlap onto the artwork the minimum amount necessary to give proper support Note: for the majority of art on paper 5mm should be sufficient. Artwork should be hinged to the undermount, not the back of the windowmount. Artwork must be properly centred and free from blemish caused by framing.

 
Glazing Glazing must be free from obvious blemishes and of appropriate thickness for the frame size. Preferably museum-quality glazing should be used, ie glazing that blocks more than 90 per cent of all UV rays unless work is to hang where there are already controlled UV levels (eg some museums). Must be cut to allow sufficient clearance inside the rebate of the frame. It is not acceptable for the glazing to touch the artwork. For large items and for items to be hung in areas accessible to the public, safety should be considered, eg laminated or acrylic sheet may be advisable. Final cleaning fluid should contain only deionized water and perhaps industrial methylated spirit.

 
Back board Back board needs to be strong, rigid and flat, eg hardboard or MDF with a 500 micron barrier board or Melinex sheet or similar, in addition to the undermount, pH neutral back board or foam board. Must be cut to allow sufficient clearance inside the rebate.

 
Securing the frame It is recommended that glazing, windowmount, artwork and undermount are sealed together using a gummed conservation-quality paper tape with water-soluble adhesive, before being fitted into the frame to keep out dust, insects etc. The frame must be secured with framers' points, tacks or similar. Flexible tabs are not acceptable.

 
Hanging Hanging fittings must be sufficiently strong to support the frame. Rivetted D-rings are only acceptable for lightweight works if the customer has chosen a thin moulding, in which case an additional undermount should be used.

 
Finish Dust and dirt should be removed and the glass should be cleaned and polished without smears. It is not acceptable to seal the back with self-adhesive tape; gummed-paper tape must be used and this must be carefully applied. Pads or buffers should be applied to the two lower corners. A label giving the date and the framer's name should be adhered to the back. Note: any existing labels should be preserved as this can provide provenance for the art.

 

Five Levels of Framing - Conservation Level
(second highest specifications)
Objective To visually enhance artwork and offer a high level of protection from physical and mechanical damage, airborne pollution and acids generated by framing materials, for approximately 20 years under normal conditions. Ideally frames should be examined by the framer or conservator every five years, and there should be a label advising this on the back of the frame.

 
Suitable for Collectable artwork that is to be kept for future generations, eg original paintings and limited edition prints of moderate to high value, as well as items of sentimental value.

 
Moulding No significant blemishes. Care must be taken to match the pieces. The moulding should have a rebate that is sufficiently deep to comfortably hold the sandwich. If artwork is likely to touch the moulding, this should be sealed with strips of Conservation or Cotton Museum-quality mountboard or a conservation foil and paper tape. Note: Good original frames should be retained wherever possible as these can enhance the value of the artwork.

 
Mitres Accurately cut, glued and pinned tightly. Corners to be touched up so no unfinished moulding is visible.

 
Windowmount A windowmount or slip should normally be used to visually enhance the artwork and distance it from the glazing. If close framing is required, there should be a spacer between the artwork and the glazing and this should be made from Conservation or Cotton Museum quality mountboard or plastic. The corners of the windowmount must be cleanly cut; the mountboard must be free from blemishes and there must be clearance of 1-3mm inside the rebate (clearance varies depending on frame size). Conservation-quality mountboard or Cotton Museum mountboard at least 1200 micron thick and conforming to the Guild specifications should be used. Slip moulding must be accurately cut and should not touch the artwork. Multiple mounts or deep spacers must be used to frame works with migrant or delicate pigments, such as pastel drawings, or artwork with a cockled surface. Using a fixative on pigments is not acceptable. The windowmount should, where possible, project at least 5mm over the edge of the artwork, thus holding it firmly in place. Any pencil marks on the underside of the windowmount should be rubbed out as they may come into contact with the artwork. For photographs unbuffered mountboard should be used (This is only available in Cotton Museum quality.) Note: Sometimes it is advantageous to retain an original windowmount (possibly gilded or decorated). In this case preferably a 1200 micron, but at least 500 micron, Conservation or Cotton Museum quality mountboard barrier should be cut to fit the underside of the windowmount to within a few millimetres of the window or a few millimetres beyond the opening.

 
Undermount There should be a barrier layer between the artwork and the back board; this should be made from Conservation or Cotton Museum quality mountboard at least 1200 micron thick. For photographs unbuffered mountboard should be used. The undermount should be the same size as the windowmount and hinged to it along the the longer side using a gummed conservation tape with a water-soluble adhesive. Note: Artwork stuck down onto acid board should be referred to a conservator for possible removal of the board.

 
Attaching artwork The artwork should be hinged to the undermount with T-hinges on the top edge, or a similarly reversible process should be used, such as corner pockets made from conservation or museum quality material. It is not acceptable to make hinges from self-adhesive tape; they should be made from conservation or museum quality gummed tape with water-soluble adhesive. Hinges should be weaker than, or the same paper weight as, the artwork- never heavier.

Artwork must be properly centred and free from blemishes caused by framing.

 
Glazing Float glass or better, free from obvious blemishes and of appropriate thickness for the frame size. Glass with high UV protection should be considered. Must be cut to allow sufficient clearance inside the rebate of the frame. It is not acceptable for the glazing to touch the artwork. For large items and for items to be hung in areas accessible to the public, safety should be considered, eg laminated or acrylic sheet may be advisable. Final cleaning fluid should contain only deionized water and perhaps industrial methylated spirit.

 
Back board Backboard needs to be strong, rigid and flat, and to protect the artwork from damage. Must be cut to allow sufficient clearance inside the rebate.

 
Securing the frame The frame must be secured firmly with framers' points, tacks or similar. Flexible tabs are not acceptable.

Five Levels of Framing - Commended Level
(middle of the five specifications)
Objective To visually enhance artwork and offer a moderate level of protection from airborne pollution and acid damage for around five years in normal conditions.

 
Suitable for Replaceable artwork of limited commercial and/or moderate sentimental value and where visual appearance is important. Preferably processes should be reversible.

 
Moulding No significant blemishes. Care must be taken to match the pieces. The moulding should have a rebate that is sufficiently deep to comfortably hold the sandwich.

 
Mitres Accurately cut, glued and pinned tightly. Corners to be touched-up so no unfinished moulding is visible.

 
Windowmount A windowmount or slip should normally be used to visually enhance the artwork and distance it from the glazing. If close framing is required, there should be a spacer between the artwork and the glazing. The corners of the windowmount must be cleanly cut; the mountboard must be free from blemishes; there must be clearance of 1mm-3mm inside the rebate (clearance varies depending on frame size). Standard-quality mountboard (or better) at least 1200 micron thick and conforming to the Guild standard should be used. Slip moulding must be accurately cut. Multiple mounts or deep spacers must be used to frame works with migrant or delicate pigments, such as pastel drawings, or artwork with a cockled surface.

 
Undermount There should be a barrier layer between the artwork and the back board; preferably this should be made from Standard-quality mountboard (or better) at least 1200 micron thick but, at this level, 500 micron thickness may be used for lightweight artwork.The undermount should be the same size as the windowmount and ideally should be hinged to it along the longer side. Other methods of joining the two are acceptable providing no adhesive comes into contact with the artwork.

 
Attaching artwork The artwork should be hinged to the undermount with T-hinges on the top edge preferably using gummed tape with a water-soluble adhesive, though self-adhesive water-reversible white paper tape may be used, or a similarly reversible process, such as corner pockets. It is not acceptable to make hinges from tape with a high acid content. Hinges should be weaker than, or the same paper weight as the artwork- never heavier. Hinges should be attached to the back of the artwork, not the front, and should overlap onto the artwork the minimum amount necessary to give proper support. Note: for the majority of art on paper 5 mm should be sufficient. At this level drymounting onto mountboard is acceptable providing customers understand it is irreversible. Artwork must be properly centred and free from blemishes caused by framing.

 
Glazing Float glass or better, free from obvious blemishes and of appropriate thickness for the frame size. Must be cut to allow sufficient clearance inside the rebate of the frame. It is not acceptable for the glazing to touch the artwork For large items and for items to be hung in areas accessible to the public,safety should be considered, eg laminated or acrylic sheet may be advisable.

 
Back board Back board needs to be strong, rigid and flat, and to protect the artwork from damage. Must be cut to allow sufficient clearance inside the rebate.

 
Securing the frame The frame must be secured firmly with framers' points, tacks or similar. Flexible tabs are not acceptable.

 
Hanging Hanging fittings must be sufficiently strong to support the frame. D-rings rivetted into the backboard should only be used on lightweight items.

 
Finish Dust and dirt should be removed and the glass should be cleaned and polished without smears.The back should be sealed, preferably with gummed tape. At this level good quality self-adhesive framing tape may be used but it is important to ensure good adhesion and longevity. Masking tape and parcel tape are not acceptable. Note: Self-adhesive tapes dry out and can fail. Pads or buffers should be applied to the two lower corners. A label giving the date and the framer's name should be adhered to the back. Old labels should be retained if possible and attached to the back.
