If you repeatedly on the puzzle imprints ('pump') the head of the bottle, creating a white foam. If you simply thin einschmiert the whole puzzle thus, holds the bottle of 8000 parts and 4000 but not as stated, then hold no two puzzle pieces together!
You have the puzzle quasi with the adhesive 'grout', so this white foam generously (!) Spread over the puzzle, so it flows into the crevices between the parts and to dry there. Do not worry, do not be too frugal, the glue is dry again transparent! But: The puzzle is a total of some matter, shines in the light not more so. In addition, one should not stick without backing (eg. As baking paper) in any case. The adhesive flows through the cracks in the ground and the puzzle stuck without backing then possibly at the living room table laid.
We really generous glued with a bottle of a 3000-piece jigsaw puzzle and the glue has then, as stated on the bottle, also served for a puzzle 1000 parts.
Strong buy recommendation from me!
