    Default Smoothing old painted masonite and replacing taped joins

    I haven't been able to find answers to these questions on forums.

    Is there any way to level the surface old sheets of masonite that have been painted several times and now have a dimpled appearance as well as the occasional small repair and quite a few old protruding nails to be knocked in and holes filled?

    How can I fill concave lines that show where the centre of the sheets were nailed?

    And.......it looks like tape was placed over the joins and painted over. This is peeling off. The strips are about 10cm wide. There is no paint under them so if I take off the tape there will be obvious lines where the old paint ends. Unless I use 10 cm wide coverstrips it is going to be obvious where the old tape was. Can this be fixed?

    If inside and the framing is sound then I would remove it and lay new plasterboard.

    I was hoping that wouldn't be the answer. More rooms to plaster. <sigh> The skirting boards look like they are never going to be removed as they are 23cm high and have multiple layers of paint adhering them to everything. At least they only have to be sanded as the paint is quite smooth.
    I haven't been all the way up to the ceiling but it looks like the (probably) pressed ceiling is in panels which include the cornice work as part of it. There are no joins apart from across the panels and they include the cornice. I haven't seen that before.
    Perhaps it is possible to cut away the masonite along the top of the skirting board, and bottom of the cornice after fastening it temporarily?
    The 10mm plasterboard would be almost as thick as the bottom of the cornice.
