Limewash or emulsion: what each does on a wall, and where each belongs.
Limewash has become a popular look, and it's often compared with ordinary emulsion as if they were interchangeable. They aren't. They behave differently on the wall and in daily life.

At a glance
What's the difference between limewash and emulsion paint?
Limewash is slaked lime thinned with water and pigment, brushed on in thin coats to give a soft, mottled, chalky finish. It stays porous. Emulsion is a water-based paint that forms a continuous film, giving an even colour and a surface you can usually wipe. Limewash suits mineral walls like bare plaster and brick. Emulsion suits most everyday interiors and wipe-clean needs.
Limewash vs Emulsion for Interior Walls
What each one is
Limewash is made from slaked lime and water with mineral colour added. It hardens by reacting with carbon dioxide in the air. Emulsion is a water-based paint whose binder dries into a film on the surface. That difference in chemistry explains nearly everything else.
The look
Limewash dries to a cloudy, matt finish where brush strokes and variations in the wall show through. It has soft movement and depth. Emulsion gives a more uniform colour, in whatever sheen you choose, and can look very clean and flat.
How they behave on the wall
Limewash stays open and lets moisture vapour pass through, which is one reason it's used on older lime and brick walls. Emulsion forms a film that resists moisture passing through to some degree. Neither will fix an active damp problem, and painting over damp with either will eventually fail.
What it needs underneath
Limewash needs a porous mineral surface to bond into, such as bare cement plaster, lime plaster or brick. It won't hold properly on POP, gypsum or acrylic putty, so a wall that's already finished that way may need stripping back or a limewash-look decorative finish instead. Emulsion goes over most sound, prepared surfaces.
Maintenance
Limewash chalks and doesn't like scrubbing, so marks are usually dealt with by recoating, since washing isn't an option. Emulsion, depending on the finish, can often be wiped gently. If the wall will see hands, food or children, that difference matters a lot.
Where each suits, and honest limits
Limewash suits walls where you want character and the surface is right, such as living spaces, porches and compound walls. Emulsion suits kitchens, corridors, children's rooms and any place needing a cleanable finish. Limewash won't give you the flat, even finish of a paint, and colour can vary across the wall, which is part of the appeal and part of the risk.
Limewash vs Emulsion for Interior Walls — your questions.
Can limewash go over my existing emulsion?
Not directly, since limewash can't bond to a paint film. The emulsion would have to be removed back to a suitable surface first, or a limewash-look decorative finish used instead. We check what's on the wall before recommending either.
Is limewash washable?
No, it chalks and isn't meant to be scrubbed. Light marks can sometimes be dusted off, and heavier ones are usually recoated. If you need a wipe-clean wall, emulsion is the safer choice.
Will limewash look the same everywhere on the wall?
No, and that's the character of it. Brush marks, the wall's own absorbency and thin translucent coats give it a mottled look. If you want perfectly even colour, that points to emulsion.
Does limewash cure damp?
No. It lets moisture pass through, but it doesn't stop it and won't hide an active problem. Damp needs its source traced and treated first, whichever finish you choose.
