What Does Pressure Treated Mean?

Pressure-treated timber, otherwise known as tanalised timber (due to the Tanalith E wood preservative that impregnates the wood) provides many benefits, such as resistance to the elements.Pressure-treating wood is a process which impregnates timber's cellular structure with preservative chemicals. This process typically incorporates copper and organic co-biocides, which help to repel both insects and moisture.

Sawn timber is wood that has been cut to the required dimensions but hasn't yet been pressure treated and kiln dried.

Am I Able To Cut Treated Timber To My Preferred Size?

Yes, it is possible to cut treated timber, provided that you have all the appropriate power tools, eye protection, and a respirator to hand before cracking on. Donning the correct PPE is essential as the cutting process releases tiny airborne particles of wood, possibly impregnated with the chemicals used in pressure-treating.Treated wood also cuts a little more like wet wood so some extra care should be afforded to ensure the blade doesn’t slip while cutting.

Can Treated Timber Be Painted or Stained?

Yes. Once surface moisture has stabilised, treated timber accepts most exterior paints, stains, and oils. Always confirm product compatibility with preservative type for best adhesion and durability.

What Species Are Typically Used For Treated Timber?

Softwood species such as pine, spruce, and fir are commonly used due to their treatability and structural properties. Hardwood may be used in specific applications where higher natural durability is required.

Does Treated Timber Require Maintenance?

Minimal maintenance is required compared with untreated wood, but regular inspection, re-coating, and good design detailing such as ventilation and drainage will maximise service life.
