I've had good results with wood putty on a wide variety of surfaces, but never tried on... what is that? Concrete? Fired clay? Ceramic? I'm not at all convinced the expansion of the different compounds would be compatible. Wood putty is easy to work with and may well work for you, especially if you're going to protect it from the elements. But something closer to the native material would probably be a better choice in the long run.
