Make your puzzles permanent so that you can enjoy them for years to come. They make great, personal decorations for any abode. Clementoni's puzzle glue is a generous 200 ml bottles (approximately 6.76 ounces). It should be enough to glue 3, 1000 piece puzzles. Your results will vary depending on how heavily the glue is applied.
Directions for using the glue from the manufacturer: "Take a completed puzzle and place it face up on a piece of wax paper or parchment. Lay the puzzle flat on your hard, flat, working surface and use a rolling pin or something similar to make sure all the pieces are pressed in and the puzzle is perfectly flat. You will need a piece of stiff cardboard, a credit card or even a plastic spatula to spread the glue evenly so have that ready. We recommend being conservative on how much glue you put down at one time because it can saturate the puzzle material and make it swell. On the other hand, you want to make sure that all the pieces are held together so you will need to be thorough. You can pour the glue directly onto the front of the puzzle or do it in sections. Use a sponge to make sure all the edges are glued securely. Don’t forget to do the edges of the puzzle too. The glue will dry clear. Allow the puzzle to dry completely overnight before moving it. We suggest you mount the puzzle with something like matte board or any other ridged material to keep the pieces in place."
Please note, the glue is not recommended for Wentworth Wooden Jigsaw Puzzles.
