Maintaining your composite decking is a crucial step to make it last longer. There are several ways you can maintain composite decking. You can clean the top of your wood plastic composite decking with a broom to wipe mud or dirt. Or, you can utilize a pressure washer to power wash your composite decking. Homeowners contemplating the other option want to know if it is safe to power wash their composite decking. This write-up explains if you can use a power washer on your wood plastic composite decking.

Why Homeowners Power Wash Composite Decking

The process of maintaining composite decking can be difficult and time-consuming if you are a busy person. If there is slush or grime on your wood plastic composite decking, removing it by sweeping and cleaning with a cloth and water will take much of your time.

This is true if you are busy and have other things to do. The alternative to going through that time-consuming process of sweeping or cleaning with a cloth is using a power washer. With a power washer, all you should do is stand some 1 meter away from your decking surface and spray the top.

You don’t have to bend down to get closer to your wood plastic composite decking when using a power washer. The power washer pressure will remove mud or other sticky dirt from the top of your wood plastic composite decking boards. This process of spraying with a power washer is much faster and will save time.

Power Washer on Composite Decking

Power Wash Decking

The thought of using a power washer on your composite decking should raise the alarm. This is because the power washer generates lots of pressure that when you spray it on something, it can destroy the thing if you are not careful. The same applies to wood plastic composite decking. When you are maintaining composite plastic decking, the pressure from the nozzle of the power washer can be hazardous to your wood plastic composite decking surface.

Depending on how you set your power washer, the speed at which it releases water can affect the surface of your composite plastic decking. Note that the attractive colour of wood plastic composite decking will not fade or scratch quickly. But this does not infer that the high pressure of a power washer cannot peel the surface of composite decking.

If you are maintaining your wood plastic composite decking and removing dirt, bringing the power washer too close to the surface will peel the pigment. That is why wood plastic composite decking owners will not recommend that you use a power washer on the decking.

How to Use a Power Washer

That a power washer can peel the composite decking surface does not suggest that you cannot use it on your composite plastic decking. If you understand the correct way to use a power washer, it can be a good thing to use it when maintaining your plastic composite decking. But you must stick to the recommendation of the decking maker so that you don’t void the warranty of your wood plastic composite decking.

We recommend that when you are using a power washer on your composite decking, you should not bring the jets or nozzle too close to the surface of your decking. Also, you should use a wide jet to spray water directly on your wood plastic composite decking. The nozzle or the jet is the same. If you don’t know what the nozzle or jet is, you should look at your power washer’s edge.

That small space the water gush out from is the nozzle or the jet. Using a small jet or nozzle will increase the pressure of the gushing water. And this can destroy the surface of your wood plastic composite decking. Aside from that, the pressure of your power washer should not be more than 3100 psi. A pressure that is more than 3100 psi will peel the top of your wood plastic composite decking.

You can use a pressure washer that has a fan attachment or adjustment. This will enable you to adjust the speed of the gushing water. When using the power or pressure washer on your wood plastic composite decking, you keep the nozzle at least 8” from the surface of your wood plastic composite decking. This way, you will ensure that you finish the task of maintaining your wood plastic composite decking on time without peeling the surface.

Conclusion

Is it safe to power wash composite decking? If you know how to use a power washer, you can use it on your wood plastic composite decking. You should not bring the nozzle of your power washer too close to your decking. Also, the pressure should not be more than 3100 psi.
