How to fix stained deck from mould killer?

Hi,

I used concobium mould killer from bunnings yesterday and there was some unnoticed overpsray. Today I have a stained deck. Tried warm soapy water with a soft brush (still wet from that in pic). Not much advice on product website. Any suggestions?

Re: How to fix stained deck from mould killer?

Hi @uses,

 

Thank you for your question about removing stains from your deck.

Unfortunately, it looks like the mould killer has reacted poorly with the coating on your deck.

You could start by trying Cabot's Deck Clean, but I am unsure how effective it would be at removing the stains.

The likely solution is to sand the deck back and recoat it to match the rest of your deck.

Check out How To Sand A Deck and How To Oil Your Deck for some guidance.

 

Let me know if you have any further questions.

 

Jacob
