Mold Part II
Permeability - One of the Benefits of Natural Lime Based Plasters
In this article Paul Hoafat discusses how Venetian Plasters can create a healthy environment. Part II
As Humans we have three skins. First, our fleshly skin which is breathable. It transpires. Takes in moisture and lets out moisture. Our skin which is the largest organ of our body is a marvelous creation, and one we need to learn from. Our skin offers us protection and comfort. It offers us comfort precisely because of its ability to breathe.
Our second covering is our clothing. Again our clothing which offers us protection and comfort is breathable. As a rule people do not prefer wearing plastic or vinyl but rather natural fibers because they breathe. Our Third environment is our home. We learn even from people of antiquity that homes should offer not only protection but be breathable. Why should we expect our walls to be made of plastic? That may offer protection but not comfort. It is no secret that many in the wall finishes industry are speaking against vinyl wall covering specifically because they form a moisture barrier in the wall, not allowing the wall to breathe and creating a situation in which mold is not only inevitable but encouraged.
Lime's vapor permeability is what has contributed to the longevity of historic buildings down through the centuries. Historic preservationists and conservationists have learned that you should not use harder less vapor permeable products that are cement based to do repairs or restorations on these wonderful structures.
Another reason that permeability is important because trapped water vapor can lead to condensation, resulting in eventual moisture damage, rot and mold formation. And so permeability is one of the benefits of natural stone finishes in the form of lime based plasters.
Venetian plaster finishes will provide both, a healthy environment and a beautiful background for your walls.
Whether or not you consider applying marble based or marmorino finishes to your walls always keep an eye on any mold formation and clean and disinfect the area immediately if you discover any mold stains. Also is a good idea to open your windows occasionally to allow the air to come in to dry out all walls and ceilings.
