make my bird bath, I used a plastic pot saucer covered with a plastic grocery
bag or plastic wrap for the frame. Place this upside-down on newspapers
or an old board. A board makes it easier to move to another spot for drying.
made my hypertuffa with equal parts of perlite and premixed concrete using
an old coffee can for measuring. Add water slowly while mixing until the
concoction has the consistency of a malted milk shake. It should be thick
enough to stay where you put it, but soft enough so that you can spread
it around. This mixture is applied to the outside of the saucer at least
one inch thick and preferably two or more inches. I did not worry about
it being even because I wanted it to look natural. Embedding either chicken
wire into the mixture as it is applied or adding cement fibers while making
the mix, will result in a stronger finished container.
Once the hypertuffa has set, usually within 24 to 48 hours, you can roughen
up the outside with a scraping tool, but do it carefully. At this stage,
the hypertuffa is very fragile and easily broken. The next step requires
patience. Leave this to dry at least one to two weeks before Trying to remove
the saucer. After you have successfully removed the saucer, the container
must cure for another four weeks. Then, fill with fresh water and place
in a flower bed. My birds seem to like having a bird bath sitting on the
ground. Moss will soon develop in the crevices.
To repair a break, I have been successful using outdoor carpenters glue
to put pieces back together and then patching surface with a bit more of
the mixture. Use the keyword "hypertuffa" in a search engine to

is a blend of cement, sand and some type of filler, usually perlite. However,
one can experiment with other materials such pine needles or wood chips.
This is put over some type of frame or into a mold to create a container
or garden art object. The goal is to create a material that is lighter than
cement and has a natural look. Because many of these fillers are porus,
much like a clay pot, they allow for some air circulation which can be beneficial
to plants. An esthetic plus is that they readily grow moss making them look
even more natural while blending into your garden landscape.
