Maston Polystyrene Primer provides perfect protection for all polystyrene base materials. It forms a protective coating on the surface and eliminates penetration of solvents. It also smoothens the rough surface by filling the uneven structure of polystyrene.
Let the surface dry around 2 hours and overpaint with any acrylic or water-based paint.
ATTENTION! Alkyd based paints might cause reaction of the surface.
