Hi all. I have an art exhibit coming up in my school. Since this is my
first year at this school, I tried ducktape to attach posters to the brick walls
all over the school for an olympiad we just had. The bricks are not the smooth
type. When you take tape off it is dirty. Ducktape didn't work well. I
found that the clear packing tape was slightly better but not great. Does
anybody have an idea and/or experience with mounting on gritty brick walls? Thanks.
