Description

PETRA is a filling coating with a self-polishing thickness made of bicarbonate lime paste, dust marble and natural additives. It is ideal to have effects that look like the natural aspect of stone, or old plasters.

Application

After applying a coat of “SABBAFOND PER MARMOREO” in order to insure a perfect drying, proceed with the preparation of the paint with the colors of the color chart and let it stand for at least twenty-four hours.
Spread the product evenly on the surface with a steel spatula and then, depending on the desired aesthetic effect, use the appropriate tool (palette knife, trowel, brush, and so on).
Before the product is quite dry, pass again the steel spatula to press relief parts and to compact everything.
Wait about ten minutes and pass again the palette knife, which is inclined and well cleaned, on the whole surface. So you will have a shiny and smooth surface.
When Petra is quite dry, you can apply, with a sponge or a glove, a coat of our product “ANTICHE CERE” as it is or diluted with water to 30%.
You can also color “ANTICHE CERE” with our toner. Or you always apply, with a sponge or a glove, a coat of our product “DELICATO” diluted with water to 30% or a coat of our product “SOFT”.
