Can anyone tell me a good method for attaching a backdrop onto pressboard that’s fastened with panhead screws. I would prefer a non-permanent method. Thanks for all your advice.
Need more info like what kind of backdrop and is it free standing or on something else?
if your backdrop is printed, water colored paper or cloth
You could try to use “rubber cement” a.k.a. Photo Glue,
it is a pure natural latex solved in white spirit,
it is available like normal glue in a tube, in cans, you can apply it with a brush , when I worked in the Graphic dept of a printshop we had it in spray cans, it is semi permanent, should be non damaging , when in doubt: test in a corner if the solvents involved does not harm your artwork. and if you spill or want to remove your backdrop the stuff is easy to remove.
good luck
You could try spray-mount. This is used to fix photos onto backing before assembling them into a frame - it’s a spray adhesive. Just be careful not to use too much as it can stain the printed side, you only need a thin coat! Also, be careful what you spray on, as the overspray will make it sticky - old newspapers are best in my experience.
You could try velcro strips along the length of your backdrop, it does not need to be to wide as it sticks together very well, you could use hot glue to secure it to the backdrop and benchwork, you can get velcro from most sewing/ craft shops very cheap, best of all it’s easy to remove the backdrop, steve UK
Your problem is going to occur at the point in time where the method you use to hold it in place fails and the whole thing fall down. For that reason I would avoid the glue methods because they all eventually fail. I think you need to develop a way to support the backdrop from the bottom and possibly use something like velcro at the top to keep it from tipping over. A groove of some type along the back edge would give you a place it so it would go below your base elevation.
