I hope this is a straightforward one .. I have a lime washed paint ( about 10 years old ) over my internal lime plastered walls all in Good condition
I just want to repaint with Earthborn paint for a different look . Do I need to wet the walls first or do a mist coat or can I just apply two coats of Earthborn clay paint on top of the lime wash?
All the advice I find online relates to newly plastered walls.
