Removed the awful decaying bamboo screening, and replaced rotten sections of decking boards. I wasn't able to get an exact match, so the thickness and groove pattern are slightly different. I'll probably use some spacers to level them out.
The fence I went round the other side and reattached any loose boards with decking screws.
I used the pressure washer to remove a lot of the old flaking paint, then brushed and vacuumed the old flakes away, then sprayed with a decking sprayer. Just the screwfix no nonsense garden paint and decking stain for the fence and deck respectively, really impressed by the coverage and colour and how easily it went on, even on the bits I had to do with a brush to avoid getting overspray on neighbours' fences and sheds.
Overall quite pleased with the result. It's an old deck so it'll never look new but hopefully it'll give it a good few more years.
Having just restained our own deck, this is really impressive!
