Features and Benefits
• Designed for Polystyrene and Styrofoam: Specially formulated to safely prepare foam-based surfaces for painting and coating.
• Excellent Surface Sealing: Helps close porous areas and air holes to protect against solvent-based paint reactions.
• Improves Adhesion: Creates a stable base that allows further coatings to bond more effectively.
• Enhances Colour Intensity: Maximises the vibrancy and coverage of paints applied over the primer.
• Protective Nitro-Combi Formula: Increases durability and surface resistance once fully cured.
• Neutral Matte Finish: Beige/brown matte coating provides an ideal base for colour application.
• Compatible with Montana Paint Ranges: Suitable for use with Montana GOLD, BLACK, WHITE, TECH and EFFECT sprays once cured.
• Smooth Application: Equipped with a Montana FLAT JET Medium cap for even, controlled coverage.
• Cap Compatible: Can also be used with FLAT JET WIDE, FAT CAP Gold/Black and LEVEL 1–3 caps for varied spray effects.
• Professional Surface Preparation: Ideal for art projects, model making, prop design and creative foam applications.
How to Use
Shake the can thoroughly for at least 2–3 minutes before use to ensure the primer is fully mixed. Apply several thin coats to the surface, spraying each layer before the previous coat is fully dry, with approximately 1–2 minutes between passes. Ensure all holes and porous areas are completely sealed for maximum protection against solvent-based paints. Allow the primer to cure for 24 hours or longer depending on temperature, humidity and substrate conditions before applying additional colour coats. Always test on a non-visible area first to check compatibility. After use, turn the can upside down and spray briefly to clear the valve and maintain consistent performance.

Real professionals who keep their word
My order arrived with the box opened and products missing. I contacted the store by email and they responded very quickly. They called me personally and assured me the missing items would arrive the next day, along with a small gift as compensation.

Cheapest paint store
Cheapest paint store I've found. Two free cans when you order over £40, crazy deals on pens at the moment. Every time I order they pack in a fredo too, which gets me excited not going to lie.

So fast! 20 hours to ship a 20kg package!
Ten out of Ten! All present and correct and a couple of free cans and stickers and the paint was delivered barely 20 hours after the order was made. What more could you ask for?

So much better than elsewhere
So much better than the main competitor (you know the ones). Always get my paint on time (unlike the competitor who take a week to ship it out sometimes). Alfreshco Dave is the man!
