How to stop glue drying in your nozzle

If you’ve lost a glue cap, you can prevent the glue from drying out by plugging the hole with a screw. Simply fit a screw into the nozzle of the glue bottle and it will be ready for you next time.

Step by Step Instructions

1 Mark for the drill holes
2 Drill the holes
3 Assemble the step
4 Attach the step to the deck
5 Sand the step
  • Step 1. Mark 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 three holes, one in the centre and two at either end. Repeat this step for the second stringer.

  • Step 2. Drill the holes

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

  • Step 3. Assemble 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.

  • Step 4. Attach 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.

  • Step 5. Sand 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.
