The time has come to redecorate, previously I have removed all the old paint and started afresh on bare wood. However as I am older I find it too much work, so I just wish to over-paint the gloss with the same colour. Will it suffice to simply rub down the paintwork with a fine sandpaper to make a key, or will I need any other preparation? I wish to do a good job that will last well.
Just sand it down. Its what most professionals do, at least when they are being watched.
Need to clean it well also with sugar soap if such is still available
Yes. S'what I've always done.
Yes.
I tend to use wet-and-dry and a bucket of water so that there is very little dust flying around. A I have got older, I have become more careful and, other than dust, can pretty much decorate a room without emptying everything out, and yet not cover everything with paint! The wet-and-dry was a huge improvement over other approaches tried so I have been doing that for years.
That's my standard technique for painting the bottom of my dinghy. But make sure you clean any flaking plaint or blisters down to solid, and re-prime if that's wood.
