Acrylic paint over cellulose based sanding sealer

[bluekingfisher]

I am about to undertake a project where I will be using MDF to create a raised wainscot panelling system in my hallway.

After I "raise" the MDF panel I believe I need to seal the exposed now faces of the MDF to ensure an even paint coverage?

I have a gallon of cellolose based sanding sealer which I was intending to seal the MDF with. Then top coat with Leyland actylic Eggshell paint.

Is this a suitable combination? will I need to undercoat/primer after sealing. Is Leyland Acrylic Eggshell a suitable paint for MDF.

Any advice greatly recieved.

Many thanks

David
