Prior to installing CrabWood composite decking,

Products need to be installed on clean flat solid surface.
Outdoor decking is required to installed onto the joists, to ensure there are enough spaces for drainage and aeration-drying.
If possible, please place the decking material on the installation site about 72 hours for acclimation.

Install Joists

Initially use a percussive drill or an electric hammer to drill the holes on the concrete surface along the length of the joist. Ensure to drill a hole every 400mm apart for residential use and every 300mm drill one hole for commercial use. As shown in the figure (1).

FIGURE 1

Install End Clips

A .) Lay the joists centering them to the pre drilled holes and keeping them 400 mm apart centre to centre ( Joist ) and position the end clips as shown in figure (2), Fix the end clips by screws after pre-drilling holes.

B.) As shown in the figure (3), insert the edge decking board into the clips slot.

Install Deck

Method 1：

Plastic clip PF-1 and Locking clip LC-1

Plastic Clip PF-1

Locking Clip LC-1

1. As shown in the Figure (4), put the boards in position.

2. As shown in the Figure (5), slide the plastic clips PF-1 and the locking clips LC-1 into and along the groove till it ends on the joist.

Attn：Each board only requires one locking clip in the middle positioned between joists.

3. As shown in the Figure (6) pre-drill the joist and fix all the clips PF-1 with screws.

4. Repeat Step 1-3.

Method 2：( FOR WET AREAS )

Stainless Steel Clip MF-1

MF-1
1. As shown in the Figure (7) put the steel clips in place

Figure 7

As shown in the Figure (8) and (9), pre-drill the joist, then fix the clips with screws.

2. As shown in the Figure (10) push the next board into position.

Repeat Step 1-3

Install Skirting Profile

As shown in the Figure (11) and (12) pre-drill the skirting board according to the actual joist span, then fix it with screws.

Notes

As shown in the figure (13 ) when installing the decking board against a wall or any obstacle, gap should be at least ≥ 10mm. ( for expansion )

As shown in the figure (14 ) Two (2) joists is necessary when installing the end of decking, gap between (2) joists should be ≥20mm. And gap between (2) ends of decking should be ≥6mm for a decking length of 2.9mtr . This is important for

faster-drainage and to keep the board dry . This will help avoid expansion caused by long term water immersion.

2. As shown in the figure (16 ) we recommend to increase the height between decking and the ground surface or leave in a drainage This is necessary for keep the decking area dry and for better ventilation to avoid expansion caused by long term immersion. Meanwhile we recommend you make a gradient of 0-30 mm between decking and ground ( end to end ) for water drainage.

Attn: Gap for drainage channel should be 600-800mm
