Composite Decking: Is it Slippery When Wet?

One of the biggest concerns that people have about composite decking is that it might be slippery when wet. This can pose a serious safety hazard, especially if you have small children or pets that like to run around outside.

The pendulum test(PTV) value is the industry standard for testing the slip resistance of a surface. It is measured in a lab by sliding a sled with a rubber foot down a board until it reaches an angle of 45 degrees. The higher the number, the more slip resistant the surface is. Generally, PTV≥36 will be considered low risk potential product. Let’s have a look at one of Veejoy Outdoor composite decking PTV value

Test Standard: EN15534-1:2014 6.4.2

Test Surface:

3D wood grain surface

Test results:

Dry condition

Longitudinal Direction:

Mean:71

Min:70

Horizontal Direction:

Mean:89

Mean:88

Wet condition

Longitudinal Direction:

Mean:59

Min:58

Horizontal Direction:

Mean:71

Mean:70

From the above data, it can be seen that this kind of composite decking whether in dry or wet conditions, its PTV value exceeds the standard 36 a lot, so whether outside is in dry or wet conditions, its anti-slip properties are able to give customers peace of mind.

At present, the anti-slip performance of composite decking on the market are more than standard, so there is no need to worry about slippery problems at all whether it’s wet or dry.
