While glue can be used to secure composite decking boards, it is not recommended as the main fastening. To link the fascia to the composite decking edges, you can use glue as a secondary fastening. Please refer to your user handbook for further information before using glue. You may also continue reading this article.
How to put Composite Decking Boards together
Joining composite decking boards is simple, and you may use clips and fasteners or screws to do it. The method you choose will be determined by the type of composite decking you’re installing. We’ll return to this topic later. Aside from clips and screws, you may use glue to strengthen and tighten your composite decking.

Use Clips and Fasteners Clips
The first step in installing composite decking is to clear the space. You should clear the location of soil and grass, then apply pesticides to prevent grass from growing back. After you’ve measured and cleaned the area, you may start digging the holes for the posts. The holes should be large enough to accommodate the posts. After that, you should mix cement and pour it into the holes.

Add frame
You may begin connecting the outer frames to the post when the liquid has set. Screws should be used to secure the frames and posts together at this point. It’s worth noting that screws were used instead of glue.
Attach joist
After the other components have been joined, you may begin attaching the inner framework or joists. Keep in mind that the joists will be attached to the frames you fastened to the posts. Make sure there aren’t more than 16 inches of gap between the joists. This is a prerequisite for a residential environment. If you’re building composite decking in a business setting, you shouldn’t leave more than 12 inches between boards. With the help of screws, you’ll be able to complete this work. You may use glue between the joists and the frame if you want to, but it isn’t required. The composite decking planks can then be installed on the joists or substructure.
Starter clips
Start by securing the beginning clip to the side of a wall. Fasteners are used to secure the starting clips to the joist. Then, to keep the composite decking boards in place, put them into the starting clips.

Screws
It’s important to note that the boards will not be screwed directly to the joist. Instead, the clips are secured to the joist. Only grooved decking planks are suitable for this technique of installation. The decking planks with no grooves are screwed straight to the joists. As a result, you will just employ screws instead of clips and fasteners. After you’ve done installing the first set of boards, you may proceed to the next step. You’ll need intermediate clips if you’re using grooved boards.
If you’re working with ungrooved panels, you’ll need to utilize screws. Make sure the boards are spaced 5 millimeters apart. Because of expansion and contraction, this gap is critical. The decking planks will buckle if there isn’t enough room between them. Rails or the post that will support your pergola can be attached to your decking. You should create a step at this point if you wish to build one. After you’ve installed all of the composite decking boards, you’ll need to finish by covering the edges.

Covering the Composite Decking’s Edges
Fascia boards can be used to cover the borders of composite decking. If you choose this option, the screws in your composite decking skirting will be visible. This procedure is straightforward, but it necessitates the use of the appropriate fascia boards. Screws should be used to secure the fascia to the frame or substructure. After you’ve pre-drilled holes in the fascia boards, that is. Your fascia boards should be screwed in place.
The glue should not be used as the primary fastening. After you’ve used screws, you may apply glue to the area to make it more secure. This step is optional, and it will not improve the quality of your fascia over one that does not employ glue. Please ensure that the expansion spaces between the fascia board ends are correct. A minimum of 0.2 percent of the board length should be left for growth.
Conclusion
When installing composite decking boards, we do not advocate using glue as the primary fastening. To attach your composite decking boards, you can use either clips or screws.
