fixing tips

Would like to wish everyone a healthy and prosperous 2018.Having purchased some id backscenes a few years ago and fixed them with wall paper paste on to hardboard when finished they looked good unfortunately within a month bubbles and creases started to appear and looked so bad i ripped the lot off and painted  in sky blue emulsion.
With hindsight i think i applied to much paste. :roll:
Having seen some of the results other people have achieved using id backscenes i am considering having another go but this time using the self adhesive ones, i believe you have the option of leaving the backing paper on and using a spray adhesive like 3M .
Can anyone  give me any advice on the best method for fixing these as im desperate to get it right this time. 

Well, I have used spray adhesive to fix paper backscenes to hardboard and they came out OK.  Krylon is the brand I used.  They are all much of a muchness I think.

Hi Richard,

I hate the stuff. A very light coat is sufficient. And you normally only  get one chance at. Lay it on a slighter larger base, that way you can concentrate on making sure there are no bubbles (use a small paint roller as you unroll it onto the board), rather than making sure it's dead square.Then again, I don't need back-scenes as such as I  have 2-sided operations and viewing. Back-ends is about it.

Which 3M product are you contemplating? #77 is the most common, and it has a reasonable tack time (1-15 minutes) that allows re-positioning. John (Brossard) uses Krylon (as do I), which is archival quality and has quite a long tack time compared to the 3M products.

I have tried all three methods - wet adhesive caused bubbles and any on the face lifted the printing. More success was achieved with 3M Spraymount on oversized mountboard - spraying the reverse of the sheet and a light coat on the board and using the tube it came in to roll it on to the backing. Leave overnight to dry before trimming and introducing any curves. ID also do it as a self adhesive option and this is polypropylene and more robust than the paper versions. Again, peel off a bit of the backing and roll on to a sheet of mount board cut a bit oversize and apply pressure with the tube or rolling pin. Must say I think this last option is by far the best way of using these very good backscenes.

   Thanks for the advice on that, when you say you had the best results with the id backscenes using the self adhesive method what board did you apply it to and was it sealed with paint or varnish prior to fixing.

I used mount board for the self adhesive sheet. Not sure whether you are referring to sealing the backing board or the scenic one but the answer is no in both cases. The self adhesive one is sealed anyway and I had no reason to seal to protect the backing board. Be careful if you plan using the paper versions as the surface can be damaged with moisture, I have found.
