Hi everyone.

Will mosaic brick last outside in contact with the ground covered by snow etc? Or should I seal the mosaic and ground touching part of the brick with auto undercoating spray before mosaicking?

context: the local women's services agency asked my garden club (and others in their service area) to plant a special bed in honor of their 40th anniversary. So we designed 4 raised beds which my dh and a young man who happened by just built out of pieces of curbing (HEAVY) given to us by the city. To achieve a 4 beds each 2 foot square, we had to have the curbs just touch at their corners. (curb pieces were just 2 feet long). Sooo I bought some tall "bricks", not cement, that are square to mosaic 2 sides and put in each corner. so 2 sides will be mosaicked and 2 sides will be mortored to the curbing.

Should I seal? will it work?
