Damage limitation.

I've been beset by problems with my photo backscenes bubbling up from the backdrop.  Mostly due to the wrong adhesive being used thanks to a lack of tech  info from the producer.  Fair to say he replaced the scenes and offered to do so FOC. In the end I paid him a modest material covering fee and freight from the USA. Honour was satisfied as folk who trade fairly deserve to be treated fairly in return.  I had an additional problem in the fact that I didn't brace the hardboard backdrop well enough and it flexed. I tried pumping foam in the gap between it and the wall but that pushed it into a convex shape so made it worse. In the end I decided on a clean break and cut out the backdrop and foam back to bare wall and will start all over again. This time I will clad the wall with 9mm MDF board, then cover that with styrene sheeting and apply the self adhesive backscene onto that.  here's where it starts again.  There is a ton of repair work to be done once the backscene is back in place.
