Transparent puzzle adhesive

I’ve used it on 2000 pieces puzzle (98cmx75cm) and 1000 pieces. It lasted for 3 layers on the big one and two on the smaller one. It worked brilliantly. The puzzles are up and hanging in frames. Very easy application. Made the puzzle colours more vivid and gave a bit of shine to the finish. After reading some other reviews I would have some advice on the application process. Press the bottle nozzle firmly to the puzzle and squeeze the bottle so a lot of glue pours out. Spread gently the glue. Make sure there’s a big puddle of it before spreading it. Don’t press hard with the sponge as it might cause the paint to rub off the puzzle pieces. Also if you have low quality puzzle, it might affect the final result.

Good glue but could have been more stronger, as some of the pieces came apart, the amount you get it good but glue needs to be stronger and thicker.

Good product, did what it says

Pleased with how this works even on a wooden puzzle. It’s important to do a good number of layers

Works very well. I gave two coatings front and rear, it held the 1000 jigsaw together very well and you can’t tell it is applied to look at. Enough left for another 3-4 1000 jigsaws as well

The glue is rather watery but comes out of the sponge applicator easily enough. The directions state it should be applied to the right side of the jigsaw and it's advisable to put a plastic or greaseproof backing behind the jigsaw first as some glue inevitably seeps through. It any of the backing touches the glue on the front of the picture it will stick fast. The glue takes an hour or so to dry but even after 3 applications over a day, some pieces were still not securely stuck (and this after I added a 4th coat over the back as well for good measure). I ended up putting sticky backed plastic film on the back of the jigsaw to secure it, as I wanted to hang the picture on a wall without putting it in a frame. There was plenty of glue in the bottle for 4 applications of a 1,000 piece jigsaw, with some to spare. I made sure to apply it evenly and it dried totally clear and was invisible.

Apply as per instructions, easy to use, I have applied 2 layers of glue to a 1000 ps puzzle and believe I could do another x2/3, sturdy hold- so great amount/size- enjoyable to apply,

Very easy to use and works
