Breathable Paint

Q: What makes a paint truly breathable for lime plaster?

Breathability in paint refers to its ability to allow water vapor to pass through, preventing moisture buildup behind the surface. For lime plaster, this is crucial because the substrate itself needs to “breathe” to avoid trapping dampness. Truly breathable paints, like lime wash or clay-based emulsions have high vapor permeability ratings and contain no synthetic barriers such as acrylics or vinyls.

Q: Can breathable paint help prevent damp problems in older buildings?

Yes. Breathable paint is especially beneficial in heritage properties with lime plaster, where modern impermeable paints can trap moisture and lead to damp issues. By allowing vapor to escape, breathable paints help maintain a dry, healthy wall structure and reduce the risk of mold or structural decay.

Q: Is breathable paint suitable for both interior and exterior lime plaster?

Absolutely. While some breathable paints are formulated specifically for interiors (like claypaint), others such as traditional lime wash, are ideal for exterior lime render. Choosing the right type depends on exposure levels, desired finish, and durability requirements
