More fun. A stain manufacturer and I have been having discussions on the susceptibility of boiled linseed and paraffinic oils to mildew, mold, and general discoloring due to moisture and environmental exposure.
I have agreed to a test. It has been approved by the other party. Any suggestions would be welcomed.
Western Red Cedar 2 x 6 board, new wood purchased last year and never stained or exposed to the weather. It has been cleaned with Restore sodium percarbonate wood cleaner, lightly pressure washed, and brightened with citric acid a week ago. The citric was gently washed off with water after about an hour of brightening.
The cedar is very dry, Delmhorst reads at 8%. It is in my office at the moment.
The plan is this. The cedar board will be divided into 4 sections. One section will be treated with boiled linseed oil, the most common oil in exterior wood stains. It has been confirmed by the manufacturer that it does not contain any fungicides/mildewcides.
One section will be treated by paraffin oil. No Ken, not baby oil, one refining step down. Again as with the linseed, no additives.
One section will be untreated and left alone. The last section will be wrapped in plastic.
Both the linseed and paraffin oil will be allowed to dry inside for at minimum a week. Reason for this is it is Spring, and I do not want any pollen to accumulate on a "tacky" surface.
The board will then be set outside my home in a shaded area, about 1.5" from the ground to encourage moisture exposure.
