Hi,
Door linings should have a coat of primer on them prior the walls being plastered. The reason for this is that as plaster drys out it will want to shrink. If the door linning is not sealed with a coat of primer this could encourage the moister in the plaster to soak into the linning causing it to dry out too quickly and potentially crack.
