THE ROMAN CONNECTION
ANCIENTLY, THE ROMANS USED a mixture of hydrated lime and powdered pumice to form incredibly durable concretes, mortars and plasters—and the evidence of their pozzolanic hydrated lime rendering wisdom is still sticking to walls and columns centuries later.
SMART, SIMPLE, ENDURING
The Romans built the infrastructure of their empire using a brilliant formulation of four ingredients: hydrated lime—a cementitious product made from limestone that was heated to drive off the carbon dioxide and transform the Calcium Carbonate into Calcium Oxide (lime)—water, aggregate, and pozzolan. The Romans knew pozzolan as pulvis puteolanus; referred to today as volcanic ash or pumice pozzolan.
Unlike today’s quick-setting Portland cement-blended plasters, Roman methods produced breathable, flexible, self-healing plasters that were not nearly as susceptible to brittleness, chemical attacks, and other problems that plague modern cement products. Even better, lime pozzolan plasters are also beautiful to work with.
Another advantage of a pozzolan-charged lime plaster formulation like Limestrong Build is this: the lime component is not limited to exclusive, expensive, far-away natural hydraulic lime (NHL) deposits that inherently contain the needed hydraulic impurities (silicates). Hence, pozzolanic hydrated lime (PHL) plasters and bonding mortars can be formulated using the purest natural American pozzolans and limes.
WRAPPED IN OLD-WORLD GENIUS
Limestrong Build plasters put the strength, durability and beauty of old-world genius in the capable hands of today’s plasterers. Our plasters are the result of the cooperation between Hess Pumice, a natural pozzolan pioneer, and Ryan Chivers, a seasoned lime plaster professional with an intense and well-traveled interest in old-world plasters and plastering techniques.
Limestrong Build plasters are safe to use and straightforward to mix, handle and apply. It is ideal for both outside and inside finishes, and creativity with color and texture is unlimited. Naturally white in color, Limestrong is easily tinted and colored using natural oxide color pigments.
Like Roman plaster finishes, Limestrong Build finishes are impressively-enduring, flexible, heal autogenously, give off no volatile organic compounds, provide ample working times, and result in unique and beautiful finishes—a medley limited only by the creativity and skill of the hand that applies it.
“Withstanding the test of time” is a common cliché, but is fully applicable when considering the physical body of evidence on and in countless structures world-wide—lime pozzolan plasters simply last. Beautifully.
