Lime Benefits All of Us
Lime paints and plasters initially gained favor in the U.S. because
of their beauty. But these aesthetic products offer critically
important sustainable performance advantages, too.
Lime has the following beneficial qualities:
A purely natural material
Correctly formulated as a truly sustainable lime paint or plaster, a
pure, natural lime does not include any artificial admixtures,
plastics, or harmful chemicals.
Breatheabilty (high porosity, high permeability)
In our view, sustainable structures should be designed to breathe,
just as we do. If a building envelope is too air tight, moisture can
become trapped inside.
One of the outstanding benefits of using
lime as an internal or external finish is its high porosity. bioLime
allows you to build permeable wall systems, eliminating standing
condensation. A lime-finished structure "breathes", enabling moisture
If you're building in a damp or tropical climate, preventing
moisture damage is especially critical. Using lime as a finishing
material will enable you to build structures that prohibit moisture,
bacteria, mold, and mildew from forming within the building
bioLime® coatings offer thermal comfort and protection, as well as being
able to decrease energy demands from electronic climate control
systems. bioLime® coatings save energy.
Lime paints and plasters can tolerate damp and
sea-side applications that would normally
de-laminate acrylic-based plasters, latex-based
paints, conventional stuccos, and even Portland
cement and Gypsum-based plasters.
A natural antiseptic
Lime is mold-resistant and a natural biocide. Due to lime's high pH
(between 12-12.5), it serves to reduce indoor air pollutants, while
making the structure hygienically sound and easy to clean.
When structures made of lime are subjected to small movements, they
are more likely to develop many fine cracks than the individual large
cracks, which occur in stiffer cement-bound structures. Water
penetration into these fine cracks can dissolve "free" lime and bring
it to the surface. As the water evaporates, this lime is then
"re-deposited" and begins to self-fuse, healing the cracks.
explains why some old lime structures on non-stable foundations distort
with age, but do not fail.
Often, soft lime paints and plasters are used as protection for
structures, particularly from severe rain. In essence, these lime
products act "sacrificially" in protecting buildings.
when designed correctly, lime will not allow penetrating water to enter
Lime is exceptionally durable. The Pantheon, the classic temple in
Rome, is constructed of lime and spans over 140 feet. Incredibly, this
beautiful structure has lasted nearly 1,900 years. Lime's durability is
evident throughout the ages.
Low thermal conductivity
Lime plays a pivotal role in creating optimal thermal protection.
When designed correctly, a building finished with lime will keep
inhabitants warmer in cooler climates and cooler in warmer
Lime is a natural fire-retardant, making it a wise choice for
timber-frame and thatch construction.
Unlike synthetic paints and plasters, lime is unaffected by direct
UV-ray sunlight. Lime will not trap the sun's heat, nor will it crack,
fade, or lose color under continuous UV-ray exposure.
Lime surfaces feature a beautiful luminescence and are pleasing to the senses.
A lime-finished structure enhances comfort, tranquility,
and a communion with the Earth.

Difference to understand our approach.
For more than 7,500 years, lime has served as the principal binder in
mortar, plaster, render, and lime wash. Dating back to the days of
ancient Egypt, Greek, and Rome, and throughout the civilized
world–and during the golden age of lime in the 19th century and up to
modern times–lime paints and plasters have proven themselves as
extremely durable and resilient.
