What a Frame Actually Does for a Painting

Ask most people what a frame is for and they will say it makes the painting look finished. That is true, and it is the smallest part of the job.

A frame is a piece of environmental engineering. It sits between an object you care about and a room that is slowly working against it, and almost everything it does happens where you cannot see it.

The damage is slow, and that is the problem

Nothing dramatic happens to a painting in an ordinary house. There is no single event. Light takes the colour out of it a fraction at a time. The backing board turns acidic and burns a brown line into the edge of a sheet of paper over about a decade. Moist air moves in and out of an unsealed frame and condenses on the inside of the glass.

You do not notice any of it while it is happening. You notice it when you compare the painting to a photograph taken twenty years ago, and by then none of it reverses.

What each layer is actually doing

Take a framed work on paper apart and you get seven layers, and every one has a job.

• The glazing stops ultraviolet light, which breaks the chemical bonds in pigment.
• The spacer holds that glazing off the surface of the art. Without it, glass rests directly on the work, and anything with moisture in it eventually sticks.
• The mat creates that gap where a spacer is not used, and gives the eye somewhere to rest.
• The hinges hold the sheet at its top edge only, so it can expand and contract with the room instead of buckling.
• The backing board supports the work and, if it is the right board, does not poison it.
• The dust seal keeps the inside of the package clean.
• The frame takes the knocks that would otherwise land on the painting.

The one nobody has heard of is the spacer, and it is the one that prevents the most irreversible damage.

Which is why the cheap version is not a smaller version

A beautiful hand-finished moulding around a sheet of ordinary glass, with a piece of cardboard behind the artwork, is not a slightly worse frame. It is a frame that is actively damaging the thing inside it while looking expensive.

If a budget will not stretch to everything, the order to spend in is the opposite of the one most people use: conservation board first, then UV glazing, then decent hanging hardware, and the moulding last. A plain frame built properly will outlast a lovely frame built badly, and it is not close.

The one thing a frame cannot fix

Heat. Nothing in a frame protects a painting from a warm wall. Above a working fireplace, above a radiator, or on a wall that catches hot afternoon sun, the temperature cycles every single day, everything in the package expands and contracts at a different rate, and the paint film gets brittle.

There is no glazing and no board that solves this. The only answer is a different wall.

Not everything needs one

A framer who tells you every painting needs framing is not being straight with you. A gallery-wrapped canvas with painted edges is a finished object on all sides and was made to hang bare. Framing it is a choice about how it should sit on the wall, not a requirement.

Works on paper are the opposite. Unframed paper is unprotected paper, and it will cockle, discolour and pick up damage. That is not a style question.

Where to start

If you want the whole thing in order, our custom framing guides cover it: choosing how it should look, glazing and conservation, sizing and proportion, and framing in your home. The one that changes outcomes most is how framing protects a painting.

We frame original work in-house at our gallery on Davie Street in Vancouver. Every piece we sell is a signed one-of-a-kind original with a Certificate of Authenticity, free insured shipping across Canada and the USA, and a 14-day trial.
