This is the styrofoam stone I mentioned in another post.
They cut stryofoam glued it together with outdoor caulking and covered with motar, outdoor paint, and final 2 coats of poly.
I love the look of that!
Several years ago I used a stryofoam rectangular
box, spray painted it lightly with gray paint,
and it looked like a concrete planter.
Not as great as the colors on this!
Looks great! Like the real thing.
Someone shared one of these made into a planter! Very cool idea!
