Posh Chalk Patinas are great for creating depth and shadow effects in your project. Each Patina has an incredibly thick texture with a stiff cream consistency that will hold its shape on the end of the brush. Incredibly highly pigmented, this oil-based patina is the perfect finish for any project. Apply with a brush, or your fingers and easily uplift your projects. There is no need to seal the Patinas; they can take up to 30 days to cure completely. Once cured the patinas are weatherproof.
