Weathering is a natural process that effectively breaks down wood (and many other materials) over time. Exposure to water, biological components and atmospheric changes will all get the wheels turning on this process.
For homeowners, exterior wood is most hindered by this process. Rain, UV rays and the intrusive nature of wood-boring insects are all damaging realities faced. If left untreated and uncovered, the impact of these elements can be costly. No one wants a fading garden aesthetic, so it pays to act fast.
In addition, it always helps to understand the natural elements that play in your garden and just how they can affect exterior wood. In that regard, you’ll know better just how to act and what steps and treatments products you can turn to provide a helping hand. As always, we’re here with some expert guidance.
We’ll start with rain. Rain causes rot in wood that lacks the natural oils required to resist it. This is because the influence of moisture creates the conditions for microorganisms to flourish. Species such as teak, cedar and redwood contain these natural oils, however, it’s worth noting that even these can become vulnerable if exposed to extremely wet, shady environments. This can also create the conditions for surface growth of algae and even fungi.
In most cases, a finish is required to properly protect your exterior wood. A wood oil will provide the necessary means to resist water intake, whilst aiding the natural character of the wood. A quality varnish can also be used to grant a tough, waterproof seal.
Without such protection, moisture will absorb into the cells of the wood, causing them to swell and expand. Exposure to heat and warmth will, in turn, cause the cells to shrink. This natural, back and forth movement can lead to timber warping and cracking if the cells dry unevenly.
Prolonged influence from the sun and, in particular, UV rays can also be very detrimental. If left untreated, UV radiation can actually damage the wood fibres, making them less durable and more susceptible to cracking.
The first change you will likely see, though, will take the form of an unappealing colour change. Wood is photosensitive and reacts to light. UV rays penetrate the surface and induce a grey patina into the wood that causes a dull, discolouring effect. Finishing products with UV inhibiting features are your go-to here for preventing this process.
Lastly, it’s also worth considering the impact of the life that exists in your garden. Wood-boring insects, as the name suggests, are insects that feed and nest inside untreated timber. are a known component of weathering that can cause lasting damage to timber. They like to make their homes in areas with high humidity and low ventilation.
A high-quality wood preserver provides the means to protect your wood from this reality. Preservers contain biocides and insecticides that penetrate the grain, protecting it from biological threats. We always advise keeping your wood away from any damp, shaded conditions. Primarily dry timber is much, much more resistant to insect attack.
