Hey guys my names dan, I started researching sign making online and found this site and went no further. The help y'all give to eachother and the suggestions are awesome and I could not have gotten as far as I have without reading these forums.
I'm currently working on a set of signs for a store here in Delaware, they are foam board insulation. Carved letters. The sizes are one 8foot by 2ft and two 2ft by 1ft.
I used a mix of "concrete fortifier and water puddy" to coat the signs which is the stage where I am at currently. I will be posting photographs of my project shortly after this post.
