Maston Polystyrene Primer - 400ml Spray
The "No-Melt" Insurance Policy. If you’ve ever tried to spray-paint a Styrofoam model or a piece of insulation only to watch it dissolve and "shrink" before your eyes, you’ve experienced the heartbreak of solvent-melt. Maston Polystyrene Primer is the essential barrier that makes the impossible possible.
This specialized primer is formulated to be completely neutral to delicate foams. It creates a tough, protective shield over the surface, sealing the porous cells and - most importantly - allowing you to use standard solvent-based spray paints on top without any risk of the foam melting.
Key Features:
- Melt-Proof Technology: Specifically engineered for expanded polystyrene (EPS), extruded polystyrene (XPS), and other delicate foams. It stays on the surface without eating into the material.
- Surface Smoother: It helps fill the "honeycomb" texture of Styrofoam, providing a much smoother, more uniform base for your final color.
- The Universal Bridge: Once applied and dried, this primer acts as a "bridge," allowing you to use almost any decorative spray paint - even high-solvent aerosols - on top.
- High Adhesion: Grips tightly to the "slippery" surface of foam, ensuring your final paint job won't flake or peel off later.
