Limewash and Mineral Wall Coatings
Limewash is not a paint colour, it is a mineral coating that sinks into the wall and moves with it. On an old Sussex farmhouse that breathability is the whole point, and on a new build it is the only way to get that soft chalky depth without a print effect.
Where this works
- Lime plastered walls in listed and period properties
- Feature walls in bedrooms and snugs
- Damp prone masonry that needs to breathe
- Restaurant and boutique interiors after a texture led scheme
- External render on rural and coastal buildings
How we install it
- 1Establish suction
Old lime plaster drinks unevenly. We damp the wall and read how fast it takes water, then adjust dilution rather than fighting the wall with more coats.
- 2Mineral primer where needed
Modern plasterboard and gypsum skim need a mineral primer, otherwise limewash sits on the surface and dusts off when you brush past it.
- 3Cross hatch by hand
Wide block brush, cross laid strokes, wet edge kept moving. The movement in the finish comes from the brush pattern and the dilution, not from a glaze applied afterwards.
- 4Let it carbonate
The colour lightens considerably as it cures and only settles after a couple of weeks. We agree colour on a cured sample panel on your wall, never on a wet one.
Common pitfalls we prevent
Frequently asked
How is limewash different from chalky matt paint?+
Chalk effect emulsion is still a plastic film with a matt additive. Limewash is mineral, it bonds chemically to the wall as it carbonates and it stays vapour open, which is why it suits period and damp prone walls.
Can limewash be wiped clean?+
Not in the way emulsion can. We can add a mineral fixative for hallways and stairwells to improve rub resistance, but for kitchens and bathrooms we usually recommend a silicate paint or microcement instead.
Will it stop damp?+
It will not cure a damp problem, but it lets the wall dry rather than sealing moisture in behind a film. Fix the source first, then limewash is the right finish over the repair.
Does the colour stay even?+
It varies slightly and deliberately, which is the character people buy it for. If you want a flat even wall with no cloud, limewash is the wrong product and we will say so.
Can you use it outside?+
Yes, on mineral render and masonry. Exterior work is timed away from frost and strong sun, and usually gets an extra coat because weathering is expected as part of the look.
