Explanation: MTN Pro Primer Sprays

This week, we are highlighting the MTN Pro Primer sprays. The range includes four primers, each with a unique property to pre-treat specific materials. They ensure good paint adhesion and also act as a protective layer on the material.
Primers for spray paint are a valuable addition to any creative, DIY, or home project involving painting an object or specific surface. In most cases, spray paint adheres well to surfaces, so you might be wondering: "Why waste time on pre-treating?" A primer is used for the following reasons.
- A primer layer ensures ultimate paint adhesion.
- Primers increase the durability and lifespan of the paint.
- Primers can enhance the paint's color.
- With sandable primers, you can apply primer layers alternated with sanding to create ultra-smooth surfaces.
Using primers adds an extra step to your project. If you want the best results, this extra work can be very worthwhile.
Montana Colors Pro Line Spray on Primers
When you look at the Montana Colors PRO Primer series, there are four types of primers, each with its specific use and application. The four MTN Pro Line Primers are: the EPS Primer, the Plastic Primer, the White Base Primer, and the Gesso Primer. These primers allow you to work on many types of surfaces, including wood, plastic, canvas, ceramics, metal, and styrofoam.
Montana Colors Pro Line EPS Primer
The MTN EPS Primer is specifically designed for use with styrofoam and similar polystyrene materials. Normally, spraying paint on styrofoam or polystyrene causes the foam to shrink and deform, making it impossible to work directly with spray paint. When sprayed, the EPS Primer applies a gray, acrylic-based protective layer along the porous exterior of the object. Once dry (5-10 minutes), the EPS Primer makes it easy to apply any type of paint to the polystyrene object! To ensure full coverage before applying the spray paint, we recommend applying no fewer than five thin EPS Primer layers.
Key features of MTN Colors Pro Line EPS Primer:
- Extremely fast drying time
- Easy and quick to apply
- Contains no lead or other heavy metals
- Perfect adhesion
- Excellent coverage
Montana Colors Pro Line Plastic Primer
As the name suggests, the Montana Colors Pro Line Plastic Primer is ideal for priming plastic surfaces. Many people don't realize that painting on many types of plastic won't work without first applying a primer layer. Sometimes it just flakes off, and sometimes it never seems to dry and remains sticky. This is where the Plastic Primer comes in handy! This primer provides a transparent, colorless coating on the outside of the plastic surface. After the Montana Plastic Primer has dried, any type of paint can be easily applied to the object. What sets Montana Colors Pro Line Plastic Primer apart from plastic primers from other brands is that MTN Colors uses special additives that optimize the adhesion of subsequent paint layers. Simply put, the Montana Colors Primer grabs the paint particles and locks them in, ensuring vibrant color and a smooth finish on all paint applied to the surface once the primer has dried. We recommend applying at least three thin layers of plastic primer, allowing 5-10 minutes of drying time between each layer. Montana Colors plastic primer is perfect for use on models, plastic parts, toys, chairs, and other plastic items.

The White Base Primer from Montana Colors is ideal for use with wood, metal, and ceramics. The main purpose of the White Base Primer is to improve the adhesion of spray colors and enhance the vibrancy of your paint colors. Like other Montana Colors paints, the White Base Primer is designed for maximum coverage with extremely high opacity. MTN Colors Pro Line White Base Primer offers a solvent-based, matte white, protective coating that is extremely durable and known to be scratch-resistant. As with the other MTN Pro primers, we recommend applying at least three primer layers with 5-10 minutes of drying time for the best results.
