What it's used for

• Garden decking and patio deck surfaces for domestic properties
• Raised decking platforms and walkways in landscaped gardens
• Poolside or hot tub surrounds where a durable outdoor board is required
• Commercial outdoor seating areas and public realm decking projects

Fitting and handling

Before fixing, store boards flat and off the ground in a covered, ventilated area for at least 48 hours to allow them to acclimatise to site conditions, particularly important in the variable Welsh climate. Fix boards using stainless steel or hot-dip galvanised decking screws at each joist crossing, leaving a 5-6mm expansion gap between boards to allow for moisture movement. Once laid, apply a good-quality exterior decking oil or preservative stain to all exposed surfaces and end grain to extend service life.

FAQ

Do these decking boards come pre-treated?

These boards are not listed with a factory preservative treatment, so we recommend applying a suitable exterior preservative, decking oil, or stain shortly after laying, paying particular attention to end grain cuts made on site. This will protect the timber and maintain its appearance over time.

What length should I order for a standard garden deck?

The 3.6m length suits most standard garden deck widths and produces less waste on smaller projects. The 4.8m board is better suited to larger or longer runs where fewer joints are desirable. Measure your joist span carefully and add a small allowance for trimming before ordering.
