I built a DIY background with quickcrete and styrofoam. It never completely cured :? I used some suggestions from the board adding ammonia etc. never cured......... dried it out .......same result [/list].
So here I am with a dilema? .........so does anyone have a suggestion for a non -fish -toxic coating over the background too seal it?
I have spent lots of effort on this one and ripping it out is something I do not want to do.
