0 RPetry 564 Report post Posted August 29, 2009 Interesting. They claim that removing all the protein from the oil is what makes their "boiled" linseed oil different and mildew free. Part of their FAQ as follows: What is "boiled" linseed oil and linseed oil paint? Linseed oil paint is a collective name for many different products using linseed oil as a binding agent. Since the definition of linseed oil and linseed oil paint is loose, it includes many different kinds of products, creating much confusion for the consumer. Ironically, with all of our modern technology, it is in the knowledge of traditional methods that we find our best quality products. Allback linseed oil and linseed oil paint is made from cold pressed flax seed grown in a northern, colder climate. The product is 100% Organic. The cold pressed oil contains about 30% protein that is removed in a cleaning process. The removal of the protein is crucial for preventing mold and mildew. When the protein is removed, the oil can be boiled and sterilized. This is contrary to the linseed oil products available in most paint stores. These products are NOT actually boiled even though they are labeled "boiled". Linseed oil that has the protein cannot be boiled, it is technically impossible (the oil will become explosive when heated.) If the linseed oil is not boiled and sterilized it does not dry. Substantial amounts of chemical driers have to then be added to these "unclean" linseed oil products. The Allback linseed oil and paint is completely free from any chemical driers and dries naturally within a few days. You can apply the linseed oil paint every 24 hours at about 70 degrees ambient temperature. The longer drying time is one of the reasons why linseed oil paint is so durable and flexible after it is dry. It will not buckle or crack. Linseed oil paint "moves" with the material it is painted on (wood, for example, moves substantially during seasonal changes.)

Perhaps with them removing the protein vs. what is available here typically in the states is different? I have an open mind. Then again modern alkyds aren't 'natural' anymore - yet mildew grows on most modern oil based paints Share this post Link to post Share on other sites
0 PressurePros 248 Report post Posted August 29, 2009 I think I remember telling me something about twice boiled linseed oil not being a favorite of mold. Don't quote me on that. Share this post Link to post Share on other sites
