Lime can provide a durable surface, resistant to driving rains yet porous enough to let water vapor pass through without condensation  This makes it an excellent choice for strawbale exteriors, high humidity environments such as bathrooms, and concrete interiors like moldy cinder block basements, where its natural porosity and anti-fungal nature lends to a healthy indoor air quality.

The base coats of lime are keyed and toothed to provide a better mechanical/textured bond for the final coat(s).  Finishes can be easily maintained by homeowners and freshened up with a "whitewash" or lime paint as needed.  The white nature of the limestone makes it a blank palate for pigmentation and ease of coloring.
