Paint Type
Limewash Paint
Limewash is a mineral paint made primarily with slaked lime, water, and pigments. Traditional limewash absorbs into porous mineral surfaces and carbonates as it dries, leaving a breathable, matte finish with natural tonal variation.

Limewash paint compatibility
Traditional limewash performs most predictably on unsealed, absorbent masonry. Previously painted or non-mineral surfaces need a product-specific preparation system.
| Surface | Compatibility | Preparation | Primer or base coat | Finish | Article |
|---|---|---|---|---|---|
| Brick | Excellent on unsealed, absorbent brick | Correct moisture problems and remove dirt, loose material, and efflorescence; dampen when directed. | Usually unnecessary on suitable raw brick. | Breathable, matte, and naturally varied; exterior weathering may gradually expose the brick. | — |
| Stone | Good on suitable unsealed, absorbent stone | Identify the stone, resolve moisture issues, remove contamination, and test absorption. | Usually unnecessary on compatible porous stone. | Soft, mineral appearance with variation influenced by the substrate. | — |
| Concrete | Good on cured, porous vertical concrete | Let new concrete cure, correct moisture problems, and remove curing compounds, dirt, deposits, and loose material. | Product-specific; dense or previously coated concrete may need a mineral-compatible base coat. | Breathable matte finish; not automatically suitable for floors or constant water exposure. | — |
| Plaster | Good when the plaster and limewash system are compatible | Let new plaster cure and dry as directed, then remove dust and repair defects with compatible materials. | Raw lime or mineral plaster may not need one; gypsum and repaired areas may require a prep coat. | Matte and breathable with visible brush movement and tonal depth. | — |
| Drywall | Possible with an interior limewash system | Repair, sand, remove dust, and create the uniform absorbency required by the selected product. | Use the manufacturer's compatible prep coat or primer. | Decorative matte finish with intentional color movement. | — |
