Thanks Thomas!
In terms of Tadelakt, is the process to do:
1. A base coat of plain white tadelakt;
2. A finish coat of pigmented tadelakt; and
3. A final coat of black soap?
If I'm applying to a cob rocket mass heater, do I still need the base coat?
Which coats do I need to polish? Just the finish coat and the black soap coat?
Also, what would the ratios be in each coat? I believe that 10% pigment to lime ratio is used by weight. Is that right?
Any input appreciated! I've been scouring the internet trying to figure this out.
Cheers,
Adam
