Had I ordered on the advice of a friend for the manufacture of two photo calendars these and other spray adhesive 3M named Spray Mount and the two calendars after some practice also very good job, even though the two 200ml cans then with the last of a total of 26 photos (à 21 x 28 cm) were just empty. To complain I had so ever that there is unfortunately no indication of the fertility of the adhesive, and so I was lucky that the doses ordered, when I was finished by 4 clock with calendars in the early morning, just as submitted. By area, the approximately 0.75-0.80 m² per 200ml tin were, with the Photo Mount Adhesive seemed to me something more productive than the spray mount adhesive. What would have to complain about is that there is no detailed instruction manual for this adhesive, so how to hold or hinstellt without the adhesive mist while pulling on the image front, how then touches the photos without photos when spraying that one of the still wet glue comes on the fingertips, and from there then possibly on the front of the next to be processed photos, whether and with which one can wash off the glue, if but once something like this to the Front Page comes (benzine!), etc. - because a little detailed guidance booklets in printed form or a Youtube-movies were very useful ... But that's about it, what would criticize - have therefore ordered me just in case and the next photo calendars same times the next largest box: - ).
