Do Puzzles Need Glue to Frame?

Not always. A suitable puzzle frame can hold the pieces securely without glue. Gluing joins the pieces for handling and display, but the finished puzzle still needs appropriate support and mounting. Follow the frame and adhesive instructions for your chosen method. Framing is one of several endings weighed in our guide on what to do with a finished puzzle.

When You Need Glue and When You Do Not

Glue is a permanence decision, not a quality decision. The right choice depends on how long the recipient wants to display the finished puzzle and whether they want to re-solve it later.

• Consider glue when you want to keep the puzzle assembled. Choose an adhesive suitable for the puzzle surface and follow its instructions. Glue does not replace the backing or mounting required by your display method.
• Support the puzzle when moving it. Glue is optional, not a requirement for relocation. Keep an unglued puzzle flat on a rigid board; do not lift it by the pieces alone.
• Skip glue for supported tabletop display. Keep the assembled puzzle flat on a stable surface, away from moisture and disturbance. This leaves the pieces available to take apart later.
• Skip glue when you want to re-solve. For upright display, choose a frame designed to secure an unglued puzzle of the correct size and thickness. A backing board alone does not hold loose pieces in place.

How to Glue a Puzzle Properly

Puzzle adhesives are not all applied the same way. One manufacturer's instructions for its own puzzle conserver, for example, specify the picture surface for its standard and personalized puzzles, both sides for its wooden puzzles and the back for certain special-surface puzzles, while a permanent adhesive sheet maker directs that its sheets go on the back of the finished puzzle. Use a product only if its maker says it can be used on your actual puzzle and its finish, and check any limits the maker sets on which puzzles it covers; some makers restrict a product to their own puzzles. These steps apply whichever product you choose:

• Finish the assembly first. Make sure every piece is in place and fully seated before you apply anything. If your chosen method works from the back, plan how you will keep the whole puzzle supported while you turn it.
• Apply it the way its maker specifies. Use the side, applicator and coverage given in your chosen product's instructions; these differ between products and, for some products, between puzzle types.
• Let it set as directed. Follow the maker's drying or curing instructions, where they apply, before you move, frame or hang the puzzle.
• Decide on support separately. Adhesive joins the pieces; it does not by itself determine how the puzzle is held for display. Whether you add a rigid backing board, rely on the backing in your frame, or use a hanging method supplied with an adhesive product depends on the frame and product instructions you are following.

If you have decided to keep the puzzle assembled, compare puzzle glue and adhesive sheets by the selected product’s surface requirements, application side and handling instructions.
