Mold, Mildew, Fungus, Rot and Your Environment

Time-Tested Performance

There are plenty of articles and web sites that discuss the environment required for the success of mold to live, grow and multiply. According to research, two requirements that are accepted as fact are moisture and food. Also, what we generally call wood rot is caused by the natural action of fungi converting wood to a source of food. Oxygen, moisture and a 40°F to 100°F temperature is all that fungi need to colonize wood. Wood rot and mold can be prevented by eliminating any one of these factors. Seal-It’s solution is to control the moisture.

There are naturally occurring woods such as Western red cedar and redwood that are toxic to fungi. The source of these woods is too small or too costly to meet today’s requirement for rot resistant lumber. Wood species that are not naturally rot resistant are treated with pesticides (CCA) to try to imitate nature. The world is becoming less tolerant of using pesticides, and many countries are either banning or restricting the use of Chromated Copper Arsenate (CCA) as a means of wood preservation. The wood preservation industry has started to utilize a new chemical formula ACQ (Alkaline Copper Quaternary) as a pesticide which is reported to be corrosive to metal fasteners and be more costly than CCA.

Seal-It believes the traditional wood preservation industry has missed the obvious. The focus appears to be on killing the organism after it has colonized. However, what needs to be addressed is the environment that allows the organism to grow and flourish.
