Limewash vs lime plaster: not the same thing
People often ask for one and mean the other. The difference is thickness, and thickness changes everything about how a wall looks and how long it lasts.
Limewash is a coating
Limewash is slaked lime thinned with water and applied like paint, usually in two or more coats. It leaves a very thin mineral layer with soft cloudy variation.
It is inexpensive, fast, and genuinely breathable. It also has almost no physical presence. Run your hand over a limewashed wall and you feel the wall underneath.
Lime plaster is a surface
Lime plaster is built up in coats with real thickness. It has depth you can see across a room and texture you can feel, and it can be worked to be smooth or deliberately irregular.
It costs several times what limewash does, takes considerably longer, and lasts on a completely different timescale.
Choosing between them
If you want the soft mottled look of an old European wall and your budget is modest, limewash is a legitimate answer and we will tell you so.
If you want a surface with depth that changes with the light and reads as architecture rather than decoration, you want plaster, and limewash will disappoint you.
In short
Limewash changes the color of a wall. Lime plaster changes the wall. Decide which you are actually after before comparing prices.
