Lime Wash for Stucco, Brick and Interior Walls

A real mineral finish, not a film paint

Authentic lime wash is made from slaked lime (calcium hydroxide) suspended in water, often with natural mineral pigments. Meoded’s Lime Wash is made from slaked limestone, solvent-free, and zero-VOC, with no biocides or preservatives.

Unlike acrylic or latex paint, which dries into a plastic film sitting on top of the wall, lime wash cures through a process called carbonation: the lime reacts with carbon dioxide in the air and slowly converts back into solid calcium carbonate, the same material as limestone. On porous mineral surfaces it effectively becomes part of the wall.

• Slaked-lime mineral coating, not a resin film
• Cures by carbonation (CO2 to calcium carbonate)
• Solvent-free, zero-VOC, no biocides

Soft, cloudy, and matte

Lime wash reads as a velvety, matte surface with gentle mottling and tonal variation no flat paint can reproduce. Brushed on in a cross-hatch pattern, it builds subtle depth and movement, and as it carbonates it blooms into a softly weathered patina.

Lime wash is meant to age. It shifts with daylight across the day and matures over time into the Old-World, European plaster aesthetic that drives its popularity for fireplaces, feature walls, and stucco facades.

Breathable, mold-resistant, UV-stable

Because it is mineral and porous rather than a sealed film, lime wash is fully vapor-permeable. Walls can release moisture instead of trapping it, which is why lime finishes are trusted on historic masonry and breathable wall assemblies.

Its naturally high alkalinity (high pH) makes it resistant to mold and mildew without added biocides, and the cured mineral surface is naturally UV-resistant, so color holds rather than fading. On porous brick, stone, and stucco the bond can last for many years and will not chip, peel, or flake the way a film coating can.

• Vapor-permeable: walls breathe, moisture escapes
• High-pH surface naturally resists mold and mildew
• UV-resistant; won’t peel or flake on masonry

Where it grips, and why the base coat matters

Lime wash works best on porous, unsealed mineral surfaces: raw brick, stone, stucco, masonry, and lime or clay plaster. On those, you mist the surface with clean water and apply.

Drywall, previously painted walls, and glossy surfaces are not porous in the same way, so the wash has nothing to bond into. That is what Meoded Lime Wash Base Coat is for: it gives the surface the right absorbent mineral key so the lime wash adheres and develops its finish correctly. Skipping it on drywall is the most common reason a lime wash project disappoints.

• Raw brick, stone, stucco, masonry: mist and apply
• Drywall, painted, or glossy: prime with Lime Wash Base Coat first
• Two coats typical, brushed cross-hatch

From fireplace walls to stucco facades

Indoors, lime wash suits living-room and bedroom accent walls, fireplaces, and powder rooms. It holds up well in low-to-moderate-traffic areas; for kitchens, baths, or high-touch spots, Meoded Stain Shield can be applied to make the surface easier to wipe down.

Outdoors, lime wash is a natural fit for stucco, brick, and stone facades, exactly the surfaces that define homes across the Valley. Exteriors should be kept dry and protected from rain for about seven days while the finish carbonates and hardens.
