Dear Ivor.
I can see that as in the world of Physics we here on Clayart break down
into Theoreticians and Experimentalists. I am an Experimentalist and I was
hoping that someone with some Water Warden would try the experiment and
report.
I can hazard a guess as to what may be in the Water Warden mixture but as
is usually the case the formula is probably a trade secret.
There is a class of Silicone resins that are hydrophobic and have been used
in products to waterproof shoes (Shoe Saver TM reg.), etc. I guess that
there is some of that resin in the Water Warden mixture and the rest of it
would be inactive ingredients such as solvents. These hydrophobic resin
molecules actively repel water even from a surface that would not actually
absorb the water if it got past the resin such as silica sand. Grog is a
sort of catch all term. It can be anything from ground up bisqued clay
which is still absorbent, to kyanite or ground molechite and also ground
brick which may or may not be absorbent.
I was hoping that there would be some weird result but perhaps nothing
would happen at all.
Experiment and find the facts. There is no arguing over facts, only over
their authenticity.
