This adhesive works perfectly. I have pasted more than 5 puzzles of 500 pieces with only 1 bottle and holding is perfect. We must stress the joints and for my part, I pass two layers to ensure a good grip. The white film that forms on the puzzle when you start to paste dries quickly and does not see once everything is dry. Make sure to apply the glue protecting your table (2/3 layers of newspaper) since the glue passes through the joints and the puzzle is glued to the newspaper, nothing too serious because we do not look at the back of the puzzle !!
