looked at all your recommendations thanks, seems my sand mix idea is dead then, not viable.
so ill buy a decent algae cleaner, then use the decking oil ive got and then see how it fares. that osmo stuff is bluddy expensive, so that can be my final option if i have no luck.
just one more question, you reckon id be alright to put the oil down at this time of the year or does it need to be spring/summer?
the boards are tanalised anyway, so they should be fine through the first winter shouldnt they?
spose the same question for my tanalised shiplap sides, no real rush to treat it all? or should i still try and get it all done before winter really sets in?
Have you got your decking the right way around?
that intrigued me, was it a joke, or is there actually a right way? i just chose the side i liked the look of best 🙂
thanks a lot chaps
