How to stop composite decking stain running?

[TabithaM]

Hi all.

We've recently purchased our first home and it has a huge beautiful deck that runs the length of the house, however we have noticed lately that the colour from it seems to be 'running' (for lack of a better word). 

It sticks to the bottom of our feet and tracks maroon onto our carpets when we come inside, it stains your feet and socks if you step onto the deck without shoes on, and it is running through to the structure boards on the underside of the deck through the gaps (picture below). 

My father in law was the one who told us that the lengths were composite, but in all my research to find a solution for this, I'm finding that the common consensus is that composite wood shouldn't leak colour, so now I don't know what to think!
We really want to try and stop the colour from getting on (literally) everything, so any thoughts or suggestions for a solution would be greatly appreciated!

Hi @sheilawhittam 

Thank you for providing that extra bit of information regarding your decking. Please allow us to make some inquiries regarding the stock of composite decking back in 2015. As soon as we get more information, we'll get back to you.

Thank you for your patience.

Noticing more and more why our light floors inside are getting grey powdery stuff treading inI whiped one flip flop with damp rag.. it comes off shoe onto rag.

Hi @sheilawhittam 

There should be nothing coming off a composite deck material itself. There is either a deteriorating issue with the material which would be extremely rare or it's possible the previous owner put a coating on it, which is now weathering off. It will be interesting to hear @EricL findings

Indeed  we look forward to the findings.  I can tell you quite honestly that nothing has been applied to the surface except water and a mop. . We are the original  owner builder of our home as I said previously on this site.

Hi @sheilawhittam,

I am fairly confident considering the timeframe and look of the board that you have Ekodeck 137 x 23mm 5.4m Greystone Classic Grooved Composite Decking.

Can you measure the width and thickness of the board for me to confirm?

I have reached out to Ekodeck for their guidance and will assist further once I have heard back from them.
