gar and use a sponge or brush to scrub the surface of the pressure-treated wood. This should remove the green tint and reveal the natural wood color underneath. However, it’s important to note that removing the green tint won’t necessarily restore the full original color of the wood, as the preservative treatment can still leave it with a slightly darker or yellowish tone.

Factors that affect how long pressure-treated wood stays green

The timeframe for pressure-treated wood to lose its green tint can vary depending on several factors. The type of wood used, the specific preservative treatment, the climate and exposure to sunlight are all factors that can affect how quickly the green coloration fades. Let’s take a closer look at each of these factors.

Type of Wood: Some types of wood, such as cedar, naturally weather to a grayish color over time, which can make the green tint of pressure-treated wood stand out more prominently. In contrast, other woods like pine may retain their green tint for a longer period.

Preservative Treatment: The preservatives used to treat pressure-treated wood can also affect how long it stays green. Some treatments contain copper, which can oxidize and give the wood a greener hue. Others may use chemicals that are less prone to oxidation, resulting in a less noticeable green tint.

Climate and Sun Exposure: In general, pressure-treated wood will lose its green tint more quickly in dry, sunny climates that experience higher levels of UV radiation. In humid or rainy climates, it may take longer for the green coloration to fade. Additionally, wood that is shielded from direct sunlight may retain its green hue for longer.

Typical timeframe for green coloration to fade

As we mentioned earlier, it typically takes around six months to one year for pressure-treated wood to lose its green tint completely. However, this can vary depending on the factors we just discussed. For example, in drier and sunnier climates, the coloration may fade more quickly, while in more humid or shaded areas, it may take longer.
