Steps

1Mark for the drill holes

Start by marking the drill holes for attaching the step to the stringer. Use the square to mark a centre line all the way across the stringer. Then measure the width of the step and mark that on the back of the stringer, to work out where your holes need to be. Mark 3 holes, 1 in the centre and 2 at either end. Repeat this step for the second stringer.

2Drill the holes

Put on the appropriate safety equipment and drill the 3 holes in the stringers using an 8-gauge countersink bit. 

3Assemble the step

Apply PVA glue into the rebate. Slide the stringers into the rebate, ensuring that the grip/ripple side of the step is facing the right way up. Secure the step by using a drill driver with the supplied screws. Repeat the process for the other stringer.

4Attach the step to the deck

Place the step where you want it to go. If the ground is uneven you might want to pour some concrete to make it flat. Mark the centre in the top of the stringer and pre-drill using your countersink bit. Use the impact driver and bugle head screws to secure the step to the deck.

5Sand the step

If you want to leave the step natural, give it a light sand to remove the pencil marks. Or you can paint or stain it to blend in with your decking.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
