How do I build composite decking myself? Wood-plastic decking installation is not difficult, but it is important that you lay the decking right. When installing Ultradecking, you have to follow guidelines to lay it well. Some decking brands even provide guidelines on joist spacing and spacing between the boards. If you don’t know how to build decking, this article will guide you on how to build composite decking.

What You Should Know Before Building Composite Decking 

There are two types of composite decking boards: capped and uncapped. The capped decking is suitable for any environment; you can use it in dry and wet areas. While uncapped decking is best suited in dry areas as it does not have high moisture resistance. Depending on your area, you should select the decking board that is best suited for you.

Also, there is the ungrooved and grooved composite decking. The grooved plastic wood decking is the best option for homeowners who want a hidden installation. But if you want surface installation, select the ungrooved boards. However, while laying the joist for your decking, ensure that you space it accurately. The decking joist spacing should be between 12 and 16 inches. You should also ensure that you leave an appropriate space of 5 mm between the decking board.

Steps On How To Build Composite Decking

HHow do I build composite decking myself?

The first thing to do before you start to build your decking is to gather the materials you will need. You will need tape, saw, drill, shovel, pegs and rope. Aside from that, you will also need fasteners, decking boards and treated planks. After getting all your materials, you can start building composite decking yourself.

Step One – Prepare the Location  

Choose the location you want to build your decking and clear it to remove stones and sticks. If there are grasses in the place you want to install the decking, remove it. Also, if the area is uneven, use a shovel to level it. Once you have finished preparing the place, measure the decking dimension.

Then, spray a weed killer on the spot to prevent grass from growing under the decking. Use pegs to mark where you will place posts to serve as a foundation for your composite decking. After laying the post, you can now proceed to build the base.

Step Two – Build the Base

The base of your decking will depend on the kind you want to build. The base will be above ground level if you want to construct an elevated decking. But if you want to lay it on grass, you will have to build a ground-level decking. Suppose you want to lay your decking on the ground, cover the area with a weed control fabric or spray weed killer. Then pour gravel on the area and level it with a shovel. You can now build the base by attaching planks to the posts.

Step Three – Construct the Joists

After installing the base, the next step is to build the joist. Your decking joist will serve as support for your patio. It is on the joist that you lay the composite decking boards. You should use treated planks to prevent the wood from rotting in building the joist.

Build the decking joist by constructing the outer board and then the inner board. You should build the outer board first and then arrange it to intersect with the inner board. Remember to space the joist appropriately to prevent the decking board from caving in when people stand on it.

Step Four – Lay the Composite Decking 

As soon as you finish building the joist, start laying the boards on it. You should start from the side of the wall and take it out. If you are using grooved decking, install the boards with starter clips before using the T-clips. But if you are installing ungrooved decking, use screws. You can use a drill to drive screws from the board to the joist.

When you are done laying the decking, cover the edges. There are different ways to cover the edges of your decking. You can use a fascia board, picture framing or paint the edges with a similar colour to the decking board.

Conclusion

It’s easy to build composite decking yourself. You need to prepare the area, build the joist and then lay the decking board on it.
