Composite decking is made to resist the elements better than other decking types. Timber decking will warp, crack, break, or splinter when heat or changing temperature act on it. One advantage of composite decking is that it is strong. This makes plastic wood composite durable. As a durable decking material, composite decking is warp or sag resistant. But it does not mean that plastic wood composite is warp-proof. When building the decking, homeowners will like to save their cash by installing it themselves. Most homeowners do not know the best practice when installing their decking. That is why composite decking will warp. This write-up explains how to fix warp composite decking.

Why Composite Decking Warp

We mention before that plastic wood composite is a durable decking material that lasts longer than another decking because of its strength. But it does not imply that composite decking is damage free. If you don’t install your plastic wood composite well, then there is a good chance that it will warp.

 Amateurs that try to build their composite decking without seeking technical advice don’t know the required spacing between the boards. When they fix the boards to the joists, they do it with little to no spacing. So, when the weather becomes hot, the plastic wood decking boards will expand. Expansion of the decking boards will increase their size, and when this happens, the boards will touch any solid, unmovable object close to them.

 If your decking is not close to a wall, then the boards will touch one another, and they will be distorted or be removed from the joists. So, to prevent warping, you have to initiate damage control when installing your composite decking. What damage control suggest is that you have to follow the best practice when installing your plastic wood composite.

 The right spacing for composite boards is 5 mm between boards and 10 mm between a board and wall. When you leave the right spacing when installing your composite decking, your patio will last for a long time.
