Installing Assured Composite Decking Using Plastic Clips
Plastic Clips Allow A 6mm Gap Between Deck Boards
Fix starter clips to the edge of the framework at every joist. Screw through the hole on each starter clip with the screws provided ensuring that the screws are fully screwed into place to prevent catching on the deck board underneath.
Fix the first deck board by clipping into the starter clip. Check the deck board is securely in place before continuing.
We recommend a maximum joist overhang of 20mm.
Fix plastic clips to the first deck board at every joist with the screws provided. Place the side of the plastic clips into the deck board groove and screw down half way ensuring they are upright. Screw down fully when the next deck board is in place.
Where deck boards meet leave an 8mm expansion gap.
Continue with the same process until the last deck board, cutting deck boards where required.
There are 2 ways to fix the final deck board when using plastic clips.
1) Fix the last deck board as normal but do not fix plastic clips to the outer groove. Pre-drill holes and screw through the outer groove at an angle and into the joist with the screws provided. Start at 80mm approx and then at every 300mm approx intervals. Where the groove is not accessible pre-drill holes and screw through the face of the deck board avoiding the groove.
2) Do not fix the last 2 deck boards. Measure 2 deck boards width and 2 x 6mm gaps and mark. Fix the starter clips to the joist framework every 300mm intervals/at every joist. Screw through the hole on each starter clip with the screws provided ensuring that the screw is fully screwed into place to prevent catching on the deck board underneath.
Fix the last deck board by clipping into the starter clip. Check the deck board is securely in place before continuing.
Fix the penultimate deck board(s) into the plastic clips which are already in place leaving a 6mm gap. Slide the number of plastic clips required between the last 2 deck board grooves and fix into place at every joist using the screws provided.
