Abandoned Farm Fresco Secco by david S. Soriano
8"x8"x1" concrete platform with grout topcoat. Calcium nitrate added to "Ludox" (aqueous sodium silicate suspension) to form calcium silicate. To this milky, fluid suspension is added Celite (diatomaceous earth/ SiO2) and 'chitosan'. Acrylic paints added to this binder which allows pigment to entrain in the grout.
