Apply the white base coat. Brush a coat of white paint over the entire urn. Uneven coverage is fine — this pale base is what peeks through later.

Add the furniture wax resist. Rub furniture wax onto random raised areas, edges, the rim, and the base. Use patches, not full coverage. The wax keeps the next layer from sticking so it scrapes away easily. It dries clear, so track where you apply it.

Layer on the green. Brush your green patina color over the urn, letting the application stay a little uneven for character.

Scrape back the green. Once the green has set, scrape and rub over the waxed areas to reveal the chalky white base and create the first chippy, worn layer.

Add rust tones. Dab and brush rust-colored paint into crevices, edges, and streaks below the rim. Rub most of it back with a rag, leaving a warm haze.

Do a final scrape and blend. Once everything sets, scrape back high points and rub the layers together until the colors read as one aged, weathered finish. Match against your inspiration piece and stop when you love it.
