It's usually specialised application. Quite useful where there is existing mould like small shower rooms. It's got a slightly odd finish and it's really sticky to paint with.
More details would help but a 'normal' approach to painting woodwork would be primer followed by 2 or 3 top coats of acrylic eggshell. It might suit you to use a couple of coats of Zinnser All Coat though, that's a great paint.
If you have bare wood you will need something that can resist any staining, Zinsser Cover Stain does that. I'm looking for a reliable primer that seals redwood and is moisture vapour permeable but have yet to find one I'd recommend.
