Question 1

What is treated timber?

Accepted Answer

Treated timber is wood that’s been infused with chemical preservatives to protect it from rot, insects, and fungal decay. The treatment is usually pressure-applied to make sure it goes right through the wood, making the timber suitable for structural and outdoor use.

Question 2

Can you paint treated timber?

Accepted Answer

Yes, you can paint treated timber, but it must be dry before you do. Timber is often damp after treatment, so allow adequate drying time—this can take several weeks. Use a primer designed for exterior wood, followed by a compatible paint or stain.

Question 3

How long does treated timber last outdoors?

Accepted Answer

When properly treated and maintained, treated timber can typically last between 15 and 25 years outdoors. Its lifespan depends on factors such as exposure to weather, level of treatment, and ongoing maintenance. Well-installed and regularly checked timber that has received high-quality treatment may even last longer, providing durable support for your outdoor projects.
