 Hecht Neoprene Black Rubber Paint:
 We get inquiries
from time to time regarding alternative colors to paint concrete
pond surfaces.
Although it might
be tempting, it is to your minimum maintenance advantage to paint
the surface a very dark color. Black is the color of choice
because it absorbs light rather than reflecting it.
Black colored
pond surfaces will allow for the right ecological conditions
to exist, especially during the critical first few months after
completion of the pond.
Reflecting light
surfaces creates greater algae growth of unwanted species and
typically does not allow for the slow growing, dark forest green
beneficial surface dwelling algae.
"Blue"
and "clear" colors are to be avoided.
We recommend Hecht Neoprene Black Rubber Paint
on the surface of the pond which is below surface water level
of the pond and White Mountain Clear
Lacquer on the mortar joints, typically in the waterfall.
Using the clear
sealer on the mortared surfaces of the waterfall will both help
to reduce the leaching of akali from the concrete and create
a surface which is inhospitable to string algae. Good, clean,
tidy mortar work will also go a long way to providing a minimum
maintenance pond system. Mortar Techniques
