Priming satisfies the 'thirst' of a porous product and provides a keyed surface.
Undercoat provides film build, obliterates minor surface defects and provides a good bonding surface for the top coat.
You need to knot pine, prime it all, u/c it all and top coat. I give mdf two coats of primer and thin it out a bit. BTW the site painter should be taken round the back and shot.
