Installing a solid composite deck does not require any professional tools - you can use the same, if you are installing a timber deck - the fixing only requires a different technique. A hidden fastening system is installed on the groove side of the solid composite panel to make the deck floor smooth.
As with wooden decks, solid composite panels also require expansion gaps. This hidden fastening system creates a 6 mm uniform expansion gap between the plates and a 3 mm expansion gap between the plates. Remember, if you want to install a solid composite next to the wall, you also need to leave at least 10mm of clearance there.
Starting from a corner of the deck area, the starting clip is mounted along the edge of the outer joist. Each start clip should be focused on each external and internal joist. Use a screw clamp (provided as part of the start clamp) to use a long 1 square drill bit, also available in the bag.
Push the long slotted edge of the solid composite deck into the starter clip to check that the first panel is completely straight and secure.
After the first plate is in place, slide the hidden fasteners to the side of the deck plate.
Align the screw holes on the fasteners with the center of the joists and screw the screws down halfway with the drill provided. Don't completely tighten at this stage. Continue along the length of the board and fix it semi-fixed at each joist.
Place the second plate in place to ensure that the fasteners match the grooves. The next set of hidden fasteners are mounted on the other side of the second panel in the same manner as before. Again, do not tighten the screws completely.
Tighten the screws of the first row of fasteners.
Continue from the third step to the fifth step. After the board is in place, each line will be tightened.
When the width matches the width, the fastener creates the required 6 mm expansion gap between the deck plates.
There are two options when installing the last board. You can install it:
Flush with the fascia Or have a protruding part on the outer joist.
For fascia fixation. The pre-drilled pilot hole enters the outer joist at an angle through the edge of the deck slot. They require a pilot hole (with a 3.5 mm diameter HSS drill bit, 90% of the length of the screw).
The fascia plate is flush with the deck surface and secured with 63 mm solid composite deck screws.
For a surplus, The guide holes are pre-drilled at an angle of 45 degrees from below the deck surface by means of the outer joists.
Place the last plate in the fastener and hang it on the outer joist. The unsupported solid composite deck that is suspended should not exceed 13 mm. Drill the pilot hole and secure the plate with a sturdy composite deck screw.
If you prefer, you can install a fascia under the cantilever deck for greater stability and a clean surface.
From the beginning to the end of the fixing plate, you may need to stagger the planks on your deck. When the two ends of the deck meet, they need to be fixed in one with four hidden fasteners (two at each end of each board). On the joist.
If the joists are 50mm or wider, the joint and 3mm expansion gap will be in the middle of the joist, surrounded by four hidden fasteners. If the joists are less than 50 mm, the joists are widened with the truncated joists to secure the hidden fasteners to the joists.
