Wooden Decking in Arisaig

1. Calculate the surface area for your decking Multiply the length (L) of your decking area by the width (W): L x W = Decking Surface Area (DSA) in m² 10 x 6 = 60m²
2. Work out the coverage of your deck boards Add your deck board width (DBW) to the expansion gap length (EGL), then add the deck board length (DBL) to the expansion gap width (EGW). Then multiply these numbers. (DBW + EGL) x (DBL + EGW) = Single Board Coverage (SBC) 0.144m + 0.005m = 0.149m 2.4m + 0.003m = 2.403m 0.149 x 2.403 = 0.358m²
3. Calculate the number of deck boards you need Multiply the SBC by 1.1 to allow for 10% wastage. Then, divide the DSA by the SBC. DSA / SCB x 1.1 = Total number of boards required 60m² / 0.358m² x 1.1 = 184.36 boards – so round up to 185 so you’re not left short.

1. Start in one corner of the sub-frame and position the first board across the inner joists. You want the deck board in the opposite direction to the inner joists, ensuring that it’s flush with the frame. Position any end-to-end joins between the deck boards halfway across an inner joist so you can screw both boards into the joist for stability. Make sure you keep a gap of between 5-8mm to allow for expansion of the wood.
2. Begin to screw your deck boards to the joists. You’ll need to secure the deck board to every joist is covers along your deck frame. Use two screws for every joist. Mark where you’re going to add your screws, ensuring that they are at least 15mm from the end of the board and 20mm from the outside edges. Drill pilot holes for the screws, being careful to only drill through the deck board and not the joist. Then screw the decking screws into the holes.
3. Continue to screw in the deck boards, ensuring you leave the correct expansion gap. You can stagger the deck board joins across the deck for more strength.
4. Sand down any cut ends if you need to before applying decking preserver to protect the timber from rotting.

Properly installed wooden decking will not need a lot of maintenance. Most manufacturers recommend regularly brushing leaves and dirt off the deck, and a yearly cleaning and staining procedure. This will keep the wood in the best condition. Fluids and treatments are readily available from all DIY shops and stores.
