I've got some large photos (about 70cm * 40 cm and had a problem mounting them on mdf.....
I first mounted them with 3m spray mount without realising this was
a temp mounting product - they peeled off after a few days....!
The then reapplied 3m photo mount onto the mdf and re mounted the pics. This was more successful but about 5 months later and in this warmer weather bubbles are starting to appear as areas of the photos detatch themselves.....
Is this because there was still some of the old spray mount on the surface or is this common with photo mount.
What do people reccommend? I suspect removing the current photo will damage them so will need to get the reprinted and start again.
If I do it again on fresh photos with photo mount will I be safe of will it happen again?
Are there any better products for block mounting photos in this way?
- of do I need to prepare the mdf first by applying a pva wash or similar.
I know some question the use of MDF at all. The effect I Im trying to get is of the photos mounted ona thick, solid block about 6 cm thick I have achieved this using a sheet of MDF with a softwood 'frame' of about 5cm*5cm wood around the back edge. All edges have been sanded and painted and look great - if I could get the photo
to stay on the block of course....!
If anyone would like to suggest any other materials or approaches to achieve the effect I'd welcome your thoughts.
