Decorative Plaster and Finishes
INTRODUCTION TO LIME BASED PRODUCTS
The History of lime based finishes
The traditional lime paints and plasters date back to antiquity. We can trace the use in ancient civilizations such as India and Egypt. Some finishes are still standing after thousands of years. In later years the Greeks and Romans refined their uses to build their empires to add luxury and style to their buildings and monuments. In the early renaissance period, in what is now Italy, fresco painting was developed and used by great artists such as Leonardo da Vinci to mention one well-known exponent.
Historically, prior to 1900, lime was used for all three coats of the plaster system.
It is this method that DecoPF uses today. As much as modern buildings allow, we are using traditional techniques to paint and plaster walls the old fashion way.
What is limestone?
Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate.
ECOLOGICAL ADVANTAGES of LIME Paints/Washes/Stuccos/Plasters:
There are many benefits to using lime finishes, such as adhesion, design, breathability and anti-mold protection. Lime finishes are mineral finishes based on ‘slaked lime’ and principally inorganic stable pigments. Their high transpiration together with the carbonation reaction gives finishes excellent adhesion to mineral substrates without flaking. In addition, the natural calcium oxide composition of the products makes them resistant to attacks by bacteria and fungi, thus fighting the formation of mold inside buildings.
•They are made from non-toxic materials – Lime/water or lime/sand/water •They do not off-gas or give off harmful toxic fumes •They are anti-molding and mildew protection •They are breathable finishes •They are ultraviolet light absorbers •They can easily be cleaned up with mild soap and water
These methods and formulas are important in today’s world where the green or environmental factor is requested more and more to eliminate air pollution. All products in this offering are zero or extremely low in VOC’s and non-toxic by nature. The natural ingredients are widely accepted in the trade in Europe and follow the specification laid out in green buildings and historic preservation. This fulfills requirements specified by architects and engineers in North America. Using these well tied techniques many advantages and rewards can be gained, healthier buildings as well as sound construction that will last for many years to come as seen in the past in EU.
