Limewash is a traditional wall coating made from crushed limestone (calcium hydroxide) and water. Unlike paint that sits on surfaces, limewash penetrates and bonds with porous materials through a natural chemical process. It's breathable, naturally mold-resistant, lasts 20-30+ years, and creates a soft matte finish with organic character. Modern paint is synthetic, creates a moisture barrier, and typically lasts 5-10 years.

Generally no. Limewash needs to absorb into porous surfaces, and paint creates a sealed barrier. Your options are: remove existing paint, use lime paint instead (has binders for better adhesion to painted surfaces), or choose a different finish. We'll assess your specific walls during our consultation and provide honest recommendations.

On proper substrates like plaster, brick, or masonry, limewash lasts 20-30+ years and actually becomes harder over time through ongoing carbonation. It can be easily refreshed with a new coat every 5-10 years. This far exceeds standard paint which typically needs repainting every 5-10 years.

We mix custom colors using natural earth pigments: whites and creams, warm and cool neutrals, earth tones (terracotta, ochre, umber), and soft pastels (sage, dusty rose, pale blue). Colors have a softer, more muted quality than modern paint with beautiful translucent character and natural variation.

Limewash is very low-maintenance. For light dust, use a soft brush or dry cloth. For marks, use a gentle damp cloth with plain water. Avoid harsh chemical cleaners and abrasive scrubbers. While less scrubbable than semi-gloss paint, limewash's natural alkalinity resists staining and normal cleaning is simple.

A single feature wall takes 2-3 days including prep and multiple coats. A single room takes 3-5 days. Multiple rooms take 5-10 days depending on size. Exterior applications take 5-14 days depending on square footage. Timeline includes surface prep, 3-4 coats of limewash with proper curing time between coats, and complete cleanup.

Extremely safe. Limewash contains zero VOCs, no synthetic chemicals or toxic additives, and only natural ingredients (limestone, water, earth pigments). Once cured, it's completely inert. During application, keep pets away from wet surfaces, but there are no harmful fumes or off-gassing concerns.

Yes! Exterior limewash works beautifully on brick, stucco, stone, and concrete. Boulder's climate is suitable for exterior limewash applications. We ensure proper application to withstand Colorado's temperature swings, UV exposure, and precipitation. Exterior limewash is extremely durable and breathable.
