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.
