[Cob] Water colour- Rice Hull Ash

[Taylor Publishing-DirtCheapBuilder]

HI Patrick, are there pics up yet of this?  Was the lime plaster fresh 
so you had a fresco effect, or painting onto cured walls?

One possible solution for safe coating over the watercolor on already 
cured walls may be a layer of wood wax. I bought a can of MinWax 
furniture wax, and using a soft cloth I applied over a backsplash area 
of my clay painted sheetrock.  the clay paint turned dark, then when the 
wax dried it was back to the same color, and water splashing from the 
sink just beads up and does not sink into the plaster.

( previous to this a lime-clay paint on the area did absorb water 
droplets, but when dry there was no mark or stain seen. Can't say this 
will always be the case, so waxing over a clay wall is a natural 
solution with will let you damp wipe it in future.  And unless near a 
hot/heat source waxing clay painted walls may be a good protector from 
finger s/dirt/grease/ dust, etc. that can just be wiped off, leaving a 
protection for the wall still.)


Old fashion paste wax in a can very hard to find ( the kind mom used to 
polish floors with in the 50's)  so the MinWax was a solution,  and 
carnuba flakes of wax can be bought ( artist uses) but is very very pricey.

New subject-
a local builder in my area gave me some rice hull ash ( made from 
burning the waste rice hulls) which is used as a pozzolan with lime to 
harden/strengthen it to a strong cement.  I was surprised it was jet 
black in color, and extremely fine dust. am looking forward to fooling 
with it to add to lime putty.  My friend did say it turns lime dark gray 
and looks like cement, so that is a downer, but  am excited to test it 
for various natural building uses.

Ya'll have a good turkey day..even if it is a  vegan style Tofurkey!
