How to prevent mould on composite decking?
Im not sure what type of composite deck we have as we didn't install it, but black mould seems to grow on it every 2-3 months. It can only be removed by pressure washing which is becoming very annoying and a health hazard...does anyone know if we can apply something to the deck to prevent or slow the mould growth? The deck is next to a pool so it does get wet a lot, but even with direct sunshine daily, it doesn't stop the mould. Thank you for your help!

Re: How to prevent mould on composite decking?
Hi all - saw the thread and thought to share my insights. Mould thrives when the is constant dampness / mosture and no / limited air movement. Board spacing plays a critical role in drainage and air circulation to prevent mould, particularly in an area like that. In addition to the others advice I'd definitely look into the spacing to ensure moisture drains and the deck can breathe, as it looks quite tight.
Cheers.
Yours Kindly. For more, please follow @diy_hausdesigns

Keep us in the loop @nickomoffs would be handy to know for any future enquiries if both my plan and @Dave-1 was helpful.
