Static electricity can occur on all types and brands of composite decking, including DDecks. It is more likely to be an issue in dry climates where low level humid air combines with dust particles, which is generally the opposite for us in the UK. Static is observed more on our capped Duro360 composite decking range due to the outer shell.
Composite deck boards act as an insulating material, which means they hold a small amount of static charge. We do know that, as the boards weather, static reduced over time.
Anti-Static Spray
There is an anti-static spray available to buy to deal with the static charge. Spraying directly onto the boards will reduce static. There are a number of anti-static sprays available on the market which are suitable for use on composite decking.
We are also aware that buying a dedicated solution can be expensive, so another option is to make your own solution – see below.
How to Make Your Own Spray Solution
Mix fabric softener (which should contain an anti-static agent) with warm water (we recommend 10-15% fabric softener to water), pour into a spray bottle and apply to the composite boards. Alternatively, the solution can be spread onto the affected decking using a soft mop. One litre of solution should be sufficient for 25m2. It may require redoing after rain or if you have washed your decking.
Does Static Electricity always occur on Composite Decking?
In general, the static electricity generated on composite decks does decrease over time and most static products recommend regular use during the first year and a then when needed until it is no longer required.
Use Rubber Mats or Strips
Placing a rubber mat at the access point of your decked area can combat static electricity. Or indeed, using rubber strips on the step-edge or outer edge can also help. Rubber matting is a common strategy to mitigate the consequences of static.
An additional interesting point to note is that rattan furniture can be a conductor of static electricity, creating a sharp jolt if left unchecked. To avoid this consider placing rubber foot strips under the legs of the furniture or place the entire furniture on a large rubber mat.
Plants
Another option is to place plants on your decking in appropriate pots. Plants expel a large amount of moisture into the air which in turn creates a humid atmosphere, which assists in reducing any dry and dusty condition and thus preventing static from building up in the first place.
