Preparation - If required there are MDF sealants available at any good hardware store
or online. But this does not provide any benefit over just using an undercoat.
Undercoating - Any Acrylic black works well. We have used watered down Citadel and
Vallejo blacks as well as a number of sprays with good effect. The cheapest spray
can is ‘Plastikote’, giving the MDF a plastic feel which provides an effective base
Painting - We use water based acrylics to achieve great results. Washes, Dry brushing
and Highlighting techniques all work effectively.
