Question:-
I want to paint ONE coat of paint onto the Plasterboard to effect a durable
finish. The type of finish is not really an issue ( I.e Matt, Silk,
Weathershield , slightly textured etc.)

Any emulsion will do the job but if you really want 'durable' then
consider something with a lot of vinyl in it, like Crown mid sheen or
similar.

You will not get a good finish in one coat whatever you use (if that
matters to you.)
