How To Stop Treated Wood From Rotting

Treated wood or pressure treated wood looks great, is easy to work with and is long lasting, but occasionally we overlook it and forget about it once we have it installed. Pressure treated wood is used for fences, posts, decks, picnic tables and more – but whether we realize it or not, it can also rot. Most people think that this material is completely resistant to rot and termite infestations. This is not always correct. Just because treated wood will last longer than untreated wood doesn’t mean that it can’t be attacked by fungus, especially in the wet seasonal conditions that occur in Toronto. Read on to learn about why rot occurs so that you can become aware of how to prevent it!

How To Stop Treated Wood From Rotting

1.  Why Does Treated Wood Rot?

  • Any treated wood that 4has rotted is due to a fungal issue. The fungi that cause this are very small organisms that move into the wood and feed on it over time. This causes the pressure treated wood to decay and soften which then turns into rot. All kinds of fungal issues basically create the same problem: rot.
  • Fungi or fungal spores usually affect wet wood. The easiest way to stop the damage they do is simple: keep your pressure treated wood dry. On the occasions where dry wood is affected brown-rot fungi is to blame. This type of fungus does not need much moisture to grow. In general, though, dry pressure treated wood is less likely to rot, and in the event of rot can be more easily repaired than wet rotted treated wood.
  • Brown-rot fungus occurs most commonly in birch wood and will look like an uneven pattern or brick-like cracking. Keep in mind that although treated wood is protected by chemicals, pressure treated wood rotting is actually a physical change that will occur when micro-organisms in the air affect wet or dry wood.

1.  How Can I Prevent Treated Wood from Rotting?

  • To prevent any kind of 3wood rot on treated wood you should keep it coated in paint, oils, varnishes, protecting spray, waxes or any other kinds of substance that will enhance the longevity of your treated wood.
  • Pressure treated wood can crack and split from water exposure and this will allow fungi to get into the cracks and create wood rot. If you have a pressure treated deck this can be a harder problem to avoid. The best way to protect your treated wood deck is to apply a deck preservative. Like we mentioned earlier, stains, paints and sealants are the best choice to use. You can find these items easily at the local hardware store. Some of these protectors can also contain a fire retardant, which can be useful and help keep you and your family safe.
  • Although a sealant provides effective resistance of moisture damage (which leads to rot), you will need to apply it periodically, at least once a year. None of these products will offer lifetime protection, though. A higher grade sealant will result in longer protection, but cost can be a factor. Just be sure to inspect your treated wood for signs of wear and tear and keep it coated. Doing so will stop your treated wood from rotting!

Using pressure treated wood around your house as a privacy fence, a deck, a picnic table or whatever the structure is a visually appealing, long-lasting option that will speak for itself when you keep it protected.
