Product Information
Full details
This kiln-dried, pressure-treated sawn softwood from B&Q is an ideal choice for contractors and DIY enthusiasts working on light framing, grounds, and general joinery. Its primary advantage is the Tanalith E pressure treatment, which provides robust protection against rot, decay, and insect attacks for both internal and external projects; however, users should note that the timber is regularised and may arrive with slightly smaller actual dimensions than the nominal 3x2 label.

FAQs
Can this timber be used in direct contact with the ground?
While the Tanalith E treatment provides rot resistance, it is generally best practice to use ground-contact rated materials or a barrier if the timber is intended for long-term burial.
What is the exact finished size?
While the nominal size is 47mm x 75mm (3x2), the finished dimensions are regularised and will be slightly under these measurements.
Do I need to paint or seal the wood?
You must seal any cut ends with an end-grain preservative. Painting or staining is optional and primarily for aesthetic purposes or added UV protection.
Is this suitable for load-bearing structural walls?
This timber is typically designed for light framing and joinery. Consult with a structural engineer if you are planning to use it for primary load-bearing structural applications.
How many pieces are in the pack?
Each pack contains 20 lengths, each measuring 3 meters long.
Troubleshooting
Timber is slightly warped or bowed
This is a natural occurrence with wood; try to select the straightest lengths for critical framing members and use slightly warped pieces for shorter blocking or bracing.
Staining or discoloration on the wood surface
Variations in color are common due to the Tanalith E treatment process and do not affect the structural integrity or decay resistance of the timber.

Setup, Compatibility & Care
When working with this timber, it is essential to remember that any cutting or drilling exposes untreated wood core. To ensure the longevity of the Tanalith E protection, you must apply a suitable end-grain preservative to all cut surfaces immediately after sawing.
Store the timber in a flat, dry, and well-ventilated area before use to prevent moisture absorption. When fastening, use corrosion-resistant screws or nails, especially if the project is located outdoors, to prevent reaction with the timber treatment.
