There’s no need to prime walls and ceilings before painting with Earthborn Claypaint and Lifestyle emulsions, unless there are marks or dry stains on the surface that are at risk of bleeding through the paint. In this case, apply Earthborn Isolating Primer to block out these stains. If your wall is powdery to touch, you can stabilise it with Earthborn Wall Glaze prior to painting. On absorbent surfaces such as bare plaster, apply a diluted coat of paint followed by a full coat. For previously painted matt surfaces, simply apply the paint directly.
